Small boutique consulting | Remote (US) (some est meetings) | part-time/flexible/1099
Hi! I work with a small group of developers doing custom software development and consulting for small/medium businesses.
We are seeking a developery-data person with experience specifically with CloudSuite Distribution by Infor for one of our clients. It may be a bit of a shot in the dark, but if you have worked with this *specific* ERP system before, we'd be eager to talk to you. Reach out at "ekib.eikooc@rofni".reverse() Please include your experience in your email body/subject as we will have to quickly triage out most of the spam.
PS. Each time I post here I get ~500 emails, almost all are low effort that don't meet anything I am looking for, sometimes for months in the future. I expect it to be even worse as LLMs gain traction. I've hired 4 people from past posts (check my history if you want!), but it can take some time dig through everyone so I apologize to legitimate interests.
Just wanted to mention it was nice to see such a down to earth posting. Unfortunately, I've never even heard of the ERP you mentioned, but you sound like a good company to work for :-)
Infor is huge in the ERP space and dates back to bigger iron days(mainframe and midrange - IBM AS/400). They acquired a lot of smaller players over the years which might be way they are somewhat unknown these days unless you date yourself to that era.
Oh huh ... I actually did a lot of AS/400 & Stratus work back in the 80s. So Infor isn't written in RPG is it? the 400 actually had a decent COBOL compiler but everything seemed to end up in RPG :-/
We are actively looking for multiple software developers or software engineers to join our team (in the office, 5 days/week). These positions primarily focus on our 5off software product (puzzles/games).
There is zero expectation for you to be proficient in all aspects of the tech stack. We are looking for people who know some of these technologies and are excited to share their expertise while developing their skills and learning new things.
We welcome candidates at any experience level, with or without academic qualifications. For junior candidates, do not hesitate to share related personal projects.
FUTO is an organization dedicated to developing, both through in-house engineering and investment, technologies that frustrate centralization and industry consolidation. Our work consists of a combination of in-house engineering projects, targeted investments, generous grants, and multi-media public education efforts.
Senior Infastructure & Platform Engineer - Immich

Fusionbox | Python + TypeScript Engineers | United States| Full-time | REMOTE (Legal to work in the US)
We're a software engineering consultancy that builds enterprise software the right way. We negotiate the right to open source all our client code, maintain a handful of popular libraries, and our engineers contribute to Django core. We sponsor PyCon, DjangoCon, and Django Girls because we're invested in the ecosystem we build on.
We're looking for software engineers who value software design, system architecture, and collaboration. You should be comfortable with about half of these areas and eager to learn the rest: web application security, relational database design (PostgreSQL, beyond "SELECT *..."), Django internals, React, and distributed systems. What you'll actually work on: complex state machines for financial workflows, multi-tenant architectures with row-level security, custom database functions when the ORM isn't enough, and React frontends that handle real-time data without being a mess of useEffect hooks.
We're a small team where you'll own features end-to-end (database design to React components) and have opportunities to shape technical decisions. You'll get paid to write source code with a team that practices empathy and values work-life balance. If you've ever wished your job involved more elegant state machines and fewer marketing landing pages, let's talk: info@fusionbox.com.
Fusionbox: Leet-code style interview where you'll be expected to write correct, then optimized code in three different languages while a team of four watches. Owner calls it "pair programming."

Founding Engineer Wanted | Defense Startup | Munich/Remote
Can You Solve This?
The Challenge: An FPV drone flies at 100 km/h. You have to detect, track, and intercept it physically. No Cloud. Just on-board compute using:
• YOLOv8 Nano on Qualcomm QRB5165 Flight controller + NPU SoC. Don't know Qualcomm yet? No problem! If you have pushed Nvidia Jetson or Hailo-8 to their absolute limits, you have the mindset we need.
• Autonomous guidance using Proportional Navigation, MPC, or PID/LQR control loops
If that sounds impossible, you're right. It's one of the hardest problems in counter-drone defense. FPV kamikaze drones dominate modern warfare. Existing defense solutions are incapable of countering this emerging threat.
We're Herakles – Munich-based defense startup building autonomous interceptor drones.
What we offer: Equity | Founding Engineer role | Full tech autonomy
Your skills: Drones, Embedded Systems, Computer Vision, or Robotics
Mission: Stop FPV kamikaze drones from killing soldiers. Building the "Iron Dome" for infantry

Charted Sea | Senior Product & Platform Engineer | REMOTE | Full-time
Location: Hong Kong
https://chartedsea.com/about
Charted Sea is a small, bootstrapped SaaS company helping customers scrape very complex platforms such as Shopee (a major e-commerce platform in Southeast Asia). We focus on hard technical problems (anti-bot, browser automation, fingerprinting, captcha solving).
We are hiring a senior engineer to take ownership of our core platform: scraper orchestrator, billing & payments, customer dashboard, and parts of our AI-based captcha tooling. This is a hands-on role with real ownership: architectural decisions, setting standards, and gradually mentoring other engineers. The role is very full-stack (infra, backend, frontend).
Stack includes TypeScript (most backend & web), Rust (new backend services, migration in progress), Go (Android scraper), PyTorch (captcha solvers), PostgreSQL, Redis, GitHub Actions, Ansible, Ubuntu Linux, bare-metal Hetzner servers.
We are profitable, demand is growing fast, and engineering bandwidth is the main bottleneck. Team is small (3 engineers), fully remote, mostly async (we expect ~4h overlap with UTC+8).
Compensation: $80k–$120k USD base (depending on experience) + monthly bonus tied to company revenue (10% of net revenue shared with employees).
Apply by emailing marc.plouhinec@chartedsea.com with a short intro and CV/GitHub. I'm the founder and will personally read and reply.
TextQL | Senior Software Engineer (FT) | ONSITE | New York City | $200k Salary - $400k Total Compensation
Company: TextQL is working to drive the unit cost of a data-driven decision down to zero. We're building the agentic data lakehouse – finding trustworthy answers to hard questions from messy enterprise data without configuring schemas, moving data, or lengthy implementation roadmaps.
Roles:
* Platform: today, no one stakes their job on AI-generated queries. You'll build the system that changes that—giving agents the context to query enterprise data correctly, and the guardrails to prove it.
* Infrastructure: sandboxes are not enough for agents to work with enterprise data. You will develop reliable infrastructure for the first data platform designed to be operated agent-first – ETL pipelines, Trino clusters, and systems that let agents spin up infrastructure on their own.
Perks: 21 days PTO, free lunch, 5% 401(k) matching, top-tier health insurance, visa sponsorship
How to Apply: email gabriel@textql.com with the most significant technical challenge you have solved, GitHub if you have one, and LinkedIn and/or resume (PDF).

We are looking for a Software Engineer to lead development of a computer vision based advanced metrology system. We are seeking a long-term team member, as we have further products that will be developed and would like a key team member to grow with the role.
The Role: You will own core system development, moving between high-level scientific computing and low-level hardware control. You will also go on-site to support system deployment. This includes:
Pipeline: Python (NumPy/SciPy/OpenCV) for numerical computing and image processing.
Performance: Rust for real-time frame processing and optimized solvers. (We offer opportunities to learn Rust on the job).
Hardware: Camera SDKs (PySpin), display synchronization, and timing-critical acquisition loops.

Great to see an Elixir job. They have been so scarce on here for many months. If you ever wanna talk a little shop, hit me up, I'd love to get to know some more in the community and have been working in it full time for 10+ years. email is in profile.
Not a job. I’m exploring alignment with a potential partner.
I’m a systems builder (CS/infra founder; shut down my last startup) who spent the past two years going deep on foundational math that most engineers (and I guess many mathematicians) tend to ignore, largely at an nLab level, because standard abstractions stop composing.
I’m working toward a small, private apply-focus lab to bridge native CS intuition (computation, scale, systems) with structural, information-theoretic mathematics. The focus is composability, learning, universality, and complexity, with the intent to build, not publish.
The approach is unconventional, but intentional: staying close to real systems while reworking foundations when existing methods stop composing.
Looking for a self-funded generalist comfortable crossing CS, math, and theory that's interested in structure, information, ethics, and long-horizon work.

We're building the read layer for blockchains. The irony of "trustless" applications depending on centralized indexers like Alchemy or The Graph isn't lost on us—we're fixing it.
Shinzo embeds indexing directly into validators, turning blockchain data into a cryptographically verifiable public good. No trusted intermediaries, no API keys, no "please don't rate limit me" prayers at 2am.
We're pre-mainnet with real technical differentiation—not another "decentralized" project that's actually three EC2 instances in a trench coat. If you've ever been mass-migrated off a deprecated API endpoint or debugged why your subgraph stopped syncing, you understand the problem we're solving. We care more about what you can build than where you went to school.
We are looking for candidates that are excited to join us on a mission to raise the standard of trust online. All of our roles are fully-remote, except where specific locations are noted.
Most of the software engineering positions have been repeating here for years because we've been continually hiring for them, scaling our whole team to now over 300 people — many of those hires have come through Hacker News. We've been improving our hiring process over time, and we know some good candidates may have fallen through the cracks. Some people who tried in the past have had success going through it again, and we still pay for hiring projects.

Hey HN, I'm hiring engineers for the new Cloudflare Data Platform (https://blog.cloudflare.com/cloudflare-data-platform). We do streaming ingest and processing, managed Iceberg catalogs, and a distributed query engine—all built on R2 and the Cloudflare Edge. We're making it ridiculously easy for Cloudflare customers to build data lakes.
I'm looking for Rust engineers with experience working on databases, stream processing engines, and query engines. You'll get to work on incredibly cool tech on a huge scale.
Note: we are hiring for on-site roles in one of our engineering hubs, not hiring remote at this time.
If you're interested, shoot me an email (in profile) with subject HN and a brief description of your background and interest in the role.
I'm Stephen, founder of Integral. We're a fractional CTO firm for scaling
businesses ($10M-$100M) drowning in SaaS sprawl, broken automations, and data
scattered across 20+ tools.
What you'd work on:
- Building unified dashboards pulling from Shopify, Stripe, HubSpot, and ad
platforms (Meta, TikTok, Google)
- Multi-system automations: HubSpot → SamCart → Klaviyo → Circle cancellation
cascades
- Custom web apps (React/TypeScript, Supabase) when off-the-shelf fails
- Debugging/replacing complex Zapier/N8N workflows across client ecosystems
- API integrations with whatever the client uses—we've touched trigger.dev, hubspot, asana, samcart, AWS, and many more this month alone
The role:
You own your clients. Not "execute tickets"—actually understand their
business, propose solutions, join calls (only when needed.) Small team, high
autonomy, direct founder access. We're integration specialists, not a body
shop.
Stack:
TypeScript, React, Python, Node, Supabase/Postgres, REST APIs — end to end. Bonus points if your execution is deeply engineering-driven.
What we're not:
Big tech process, Jira hell, or "ticket monkey" work. We move
fast on real problems for real businesses. However, that does not mean we aren't highly organized and efficient.
Contractor, ~20-30 hrs/week to start. US timezone overlap required.
stephen@gointegral.co — tell me about a messy integration you've fixed.
I worked on a messy integration where data moved across multiple systems and failures were silently cascading—broken retries, duplicated records, and zero visibility into where things went wrong. I mapped the full flow end-to-end, added idempotency and clear boundaries between systems, and replaced brittle chained logic with a more explicit, observable integration. That cut down failures immediately and made the setup easy to extend when new tools were added. This kind of work—owning real systems and untangling messy automations—is exactly what I enjoy.

From talking to the hiring bot (cool tool!), It seems there's a list of countries that Posthog can't hire from for different reasons. If it's ok with you, I'd like to know if this list is up to date.
And for me specifically, I live in Argentina and some weeks ago I sent an application but I think that the resume might have been a bit hard to follow (I now updated it). Is it OK to re-send the application or are decisions for the same role final?
We have a lower bound on our location based pay which is a percentage of salary in SF, which applies to both those locations. We fixed the currencies a while ago (so people's pay don't fluctuate up and down in local currencies), which is why those two locations have different pay now.

Dialogica | Fullstack AI Agent Engineer | Santa Monica | ONSITE | $120k – $160k + Equity
We are building "Iron Man" for litigation. Our endgame is an AR application for smart glasses that gives lawyers real-time intelligence—flagging discrepancies and prompting objections during live trials. Before the glasses, we're shipping the brain: a desktop voice interface that gives lawyers "Jarvis-like" control over workflows (redlining, scheduling, billing).
The Role We are looking for a finisher to join our small engineering team in Downtown Santa Monica. We have a hard product launch on March 9th at a 6,000-person conference. The work is high-intensity (5.5 days/week) and high-impact. You will optimize voice-interface latency, build LLM workflows with LangChain, and own your code end-to-end.
At CloudX (https://cloudx.io) we’re building a new supply-side advertising platform for mobile publishers. Yes, it's ads, and yes, there's AI involved, so stop reading here if that's not interesting to you.
It's a gnarly infra problem with huge scale, combined with an interesting product space that we think legitimately benefits from tasteful AI automation. We're doing cool things with Nitro Enclaves to prove that our auctions are fair. And our founding team have done this before with great success, first at MoPub (sold to Twitter) and MAX (sold to AppLovin).
Our philosophy is to keep the team small, well-paid, and productive. We deploy every day and our monorepo CI suite takes about a minute to pass.
The best way to apply is directly through those jobs pages. I got so much direct email spam the last time I posted here, I'm afraid I have to ask you not to contact me directly about this role. If you're a real HN reader you're always welcome to contact me with any questions or concerns, but please do not just apply by sending me an email.
Any other hiring managers seeing an incredible amount of fake applicants?
Apparently I can’t attach a cover letter, but I think I might be a better fit than might be obvious from my résumé. I do tend to "think like a product owner" (to quote the job desc) and love learning new tech on the job; I have been a React fan since 2014; and I know a dozen languages, so picking up Golang sounds fun. I am a design-thinking engineer who can also write: https://alanhogan.com/blog

CareIgnition | Senior/Staff Software Engineer (Generalist) | REMOTE, Chicago (US Only)
Medical billing in America is a black box of fragmented data and inefficiency. At CareIgnition, we are building the transparency layer for healthcare. We transform massive, messy datasets into financial clarity for employers and providers.

Hi there! At Veho, we don't sell software. We ship packages. Lots of them. We have all of the interesting problems that crop up when running twinned distributed systems in AWS and the real world. It's pretty great.
We're hiring staff-level folks (L4+) in NYC and Boston: Data Scientists,
Data Engineers, Mobile Engineers, and Backend Engineers (typescript).
Personally, I'm hiring a Staff Data Engineer with the depth of experience to be a technical lead and mentor for the Data Platform team, while also shipping code. You will need to understand distributed data systems both intellectually and at an instinctive, emotional level. You should have Opinions about the wild boar book. You should probably also be comfortable writing and debugging English, SQL, and Python.
If that sounds like you, I really want you to apply for the Staff Data Engineer role on our career page. Our inbound applications are reviewed by humans.
With apologies that our first interaction requires this silliness: including one of the 7-digit numbers from the "ROS Calculator" on Veho's website in the appropriate box will heavily bias me towards believing you are a human being. That's more of an advantage than it may seem! It's worth the thirty seconds. It would also speed things along if you populate the "Location" field to confirm you are aware this is an in-office role.

Our first product helps human software engineering teams deliver more efficiently and more reliably by assisting in coordination and engineering management. But it’s built on a foundational layer that ingests data, knowledge, and process across communications and systems, exposing that to humans and AI alike.
Eventually, Kinelo will become a proper human+AI orchestration layer, managing entire companies, and our goal is to have Kinelo run Kinelo (we already dogfood it today).
We’re looking for high ownership individuals to join our small team and shape its direction. We also just opened a new SF office and new hires will have the ability to help shape company culture, engineering practices, architecture, and roadmap.

We’re looking for:
- Those who want to go 0 to 1 with high ownership: moving features and products from idea on a napkin, to prototype, to engineering UI, to shipped and polished product
- ~8 years professional experience, including the pre-LLM days with strong CS fundamentals
- A balance of wisdom from experience and optimism about the future
- Strong TypeScript and Postgres (or other RDBMS) experience at scale and with high reliability (SaaS apps, APIs, etc)
- Experience with a variety of technologies, including containerization, distributed systems, and at least one strongly typed programming language (Go, C++, Java, etc)
- Ideally experience with ML and AI systems (though expertise in ML, data science, etc is not needed for this role)
We can’t sponsor visas but relocation assistance to SF is possible.

Hey HN, this is Louis, co-founder at SightlineOS.
Yusha, Derrick, and I are building an AI-native supply chain operating system for restaurant chains. It’s a massive, overlooked space with deeply underutilized data, and we’re using modern data and ML systems to automate planning, inventory management, and spend optimization.
We’re venture-backed, NYC-based, and are hiring our first senior engineers as we start to scale. These are high-ownership roles with real production impact from day one.
You’d work closely with founders, own core systems end to end, and help shape the technical foundation of the company.

We're looking for a Senior Software Engineer to join our Core Storage team. You'll tackle genuinely hard problems: writing custom Linux drivers, optimizing lock-free data structures at nanosecond scale, building fault-tolerant distributed algorithms, and debugging issues that go all the way down to kernel internals. This isn't CRUD work - it's systems programming at its most challenging.
Competitive salary, fully remote, meaningful time off, and a yearly education budget to keep learning.
If you get excited about shaving microseconds off I/O paths and building infrastructure that simply doesn't break, we should talk.

Annex Risk | Backend + Data Engineer | Bay Area, Austin | Full-time
The cost of homeowners insurance, especially in natural catastrophe prone areas, has skyrocketed in recent years. Annex is solving this problem with better digital infrastructure for executing the transaction. Our platform enables insurance agents to quote and bind policies within 90 seconds vs. the current multi-day phone/email/fax-based transaction that is the status quo.
We grew 4x in 2025 and anticipate similar growth in 2026. We've done the above after deploying <$1.5m in funding. We have significant and growing momentum on both the insurance distribution and insurance capital sides of our business; our challenge now is scaling our engineering team to support that progress.
We're in that exciting early stage, where someone can contribute foundational new pieces to core parts of our platform.

This job is for you if you:
Love building from 0 to 1 and validating ideas quickly.
Have a fullstack skillset, enjoying collaborating across the stack.
Used to leveraging AI to code and most of your code is written with AI.
Are curious about AI integration (e.g., LangChain, Azure LLMs) and want to push boundaries.
Prefer startup speed over corporate processes.
Only apply if you've been heavily leveraging AI to code - our team moves at lightning speed.

Hack Club (https://hackclub.com / https://github.com/hackclub) is a nonprofit where 1,000s of teenagers ship real projects — games, hardware, websites, apps — and we send them free stuff in return. 100k+ teens, 140 countries. Our motto is "by teens, for teens" and we operate with radical trust and transparency.
Every month, thousands of projects come through our You Ship We Ship programs. Program authors do the primary reviews. We need someone to QA the reviewers — a second set of eyes who can tell us: are they making good calls? Catching the fake projects? Being too harsh on legitimate ones?
Responsibilities:
- Spot-check approved projects (random sampling)
- Audit reviewer consistency and catch patterns
- Define what "high quality" actually means and document it
- Train program authors to make better decisions
- Handle appeals and investigations
- Build systems that work at 100k projects/year
You'll still do plenty of hands-on review — you can't spot-check effectively without understanding the projects deeply. But your mission is ensuring the integrity of the entire process, not being the bottleneck for each submission.

• Direct line to product and customers, no layers of PMs or process
• Profitable, remote-first company with high autonomy
Stack: PHP (Symfony), PostgreSQL, React/TypeScript, Kubernetes on AWS.
We actively use AI coding tools like Claude Code and Cursor.

Most of the codebase is fairly decent Typescript. Backend knowledge a plus.
I need someone with sound judgement and taste that can plan and execute independently, but that also can communicate and coordinate complex changes well. Ingenuity and resourcefulness.
I use Claude/Cursor extensively.
I'm quite interested to hear from you if you have a project that overlaps in scope with Language Reactor.

VIVA Finance | Atlanta, GA (In Person)| Back-end Software Engineer
Target Experience Level: 2-4 years of professional software experience
VIVA is a Fintech Startup based in Atlanta, GA with the mission to build a more inclusive financial system. VIVA offers unsecured personal loans to customers who have traditionally been excluded and taken advantage of by legacy financial institutions. The VIVA difference is to underwrite heavily on employment history and set up repayments through voluntary direct deposit payments from the borrower's paycheck. Our interest rates are less than 1/3 of the rates our customers are able to get from other financing options.
We are a VC backed company and have been in business for 6 years. We have been profitable since mid 2024 and are dramatically ramping up origination volume in 2026. We are hiring an additional backend engineer to support the larger transaction volume, as well as to support new products we are launching to diversify our revenue stream (including automobile refinancing and a credit builder account). You will join our engineering team of 11 and work in a dynamic environment where you are frequently writing net new code to directly support business objectives.
Our tech stack for the back-end is fully on AWS, using Lambda and ECS for compute and Typescript as the language, but experience with this specific stack is not necessary for talented candidates. Our preference is candidates who can come in office 4 days a week to our office on the Atlanta Beltline (next to Krog Street Market). VIVA does not provide visa sponsorship, so please have authorization to work in the USA.
Send an introduction to our hiring manger (alexa@viva-finance.com) with a resume and we will be in touch!
Tiger Data (FKA Timescale) [ Global | 100% Remote | Multiple Roles: Eng, GTM, Support + more ]
We began in 2017 as TimescaleDB, focused on making PostgreSQL the best database for time-series data. As our customers evolved, so did we.
Today, more than 2,000 companies use our technology to power real-time analytics, agentic applications, and high-ingest operational systems. What started as a time-series database has become the fastest PostgreSQL for modern workloads. To reflect that evolution, we’re now TigerData—a name that speaks to our speed, precision, and ambition. The tiger has long been part of our culture: fast, focused, powerful. From “Tiger Time” all-hands to welcoming new hires as “tiger cubs,” it’s how we build—decisively, fearlessly, and with purpose.
This is not a reinvention: it’s a reflection of how we already serve our customers today.
Being able to ask questions to an LLM copilot about patterns across several billion rows, 140GB of time series data, like how the market reacts 15 minutes, 1 day, and 1 week after Federal Reserve press releases, using time_bucket() and other aggregation functions with compressed chunks, and having the copilot generate the queries and run them fast, is going to be game changing. I can ask to write a script to scrape the press releases, to run them through another agent to classify them (hawk, dove) and use that information in the time series analysis.
Even though that exploration has not produced any actionable, tradable results for me, which is why I am sharing it, eventually TimescaleDB will be one of the most important tools in fields like medical research. A researcher will be able to ask in natural language for statistically significant patterns in the data, and LLM agents will query it quickly while taking advantage of all the TimescaleDB optimizations.
G'day! There seems to be a major inconsistency in the listing for https://www.tigerdata.com/careers/ac8ae587-fd1d-4a3f-b844-74.... While the job description mentions "4-day 10-hour night shift from 7am - 5pm IST (1:30am to 11:30am UTC) Friday-Monday", the questionnaire for submission mentions "4-day 10-hour night shift from 11pm - 9am IST (4:30pm to 2:30am UTC) Friday-Monday". Might be worth rectifying.

I'm founder of Vidably and just closed a $1.5M pre-seed last week.
AI agents are about to orchestrate trillions in commerce, but today they shop on thin data: product specs, studio photos, and text reviews. Agents need evidence, not marketing. Today, the most influential product evidence lives on TikTok and Reels, outside the surfaces brands control and agents can use. Vidably puts verified buyer video directly onto e-commerce product pages through a lightweight widget. We capture that video post-purchase and link it to real purchasing outcomes. Every video is SKU-linked and structured so shopping agents can reason over it.
We're already seeing organic pull from creators and expansion from brands.

There are a lot of companies in the auth space, but we feel like we have something special:
* a unique deployment model (self-host on-prem or in your cloud or run in our cloud)
* A well designed API first approach; one customer compared our APIs to petrichor
* a mature product (the code base is nine+ years old and we've found and fixed a lot of the sharp edges around core login use cases; but don't worry, there are plenty more features to add)
* our CTO is the founder and still writes code
* a full featured free-as-in-beer version which makes the sales cycle easier; prospects often come in having prototyped an integration already
Our core software is commercial. We open source much of our supporting infrastructure. Technologies and standards that you will work with: modern Java, PostgreSQL, Docker, Kubernetes, MySQL, OAuth, SAML, OIDC.

> Thanks for posting! Are there specific language requirements, since the role is in the Japan office?
Well, can you understand the job posting? [1] It’s written in Japanese, so if you can’t read it, you’re probably not qualified to work in Japan. Some companies do hire non-Japanese speakers if your main goal is visa sponsorship to move here, but that’s not a great idea. You really need enough Japanese to get by, handle taxes, see a doctor, manage your bank account, and read emergency instructions in case of an earthquake or tsunami. It’s better to learn the language before you make the move.
Mesa | San Francisco - On-site | Software Engineers (Senior+) | https://mesa.dev/

Return (https://return.energy) is hiring a software engineer to work on platforms that accelerate the transition to carbon-free energy. Return’s main activity is building and operating industrial-scale Battery Energy Storage Systems. Our operations are located in the Netherlands, Germany, Belgium, and Spain. You will make a measurable, country-level impact on the transition to renewable energy. Return recently raised €300M to support its growth.
While we employ more than 120 people, Return’s technical team remains small with 13 members. Our platform automates processes in energy storage, monitoring, market optimization, sales, project management, procurement, construction, and customer service.
During the first three years of operation, we laid the foundation for our platforms, and we are ready to scale up. This is why we are looking for an experienced software engineer.
Your primary focus will be to further develop our battery virtualization platform, enabling customers to use slices of battery capacity distributed across our fleet of industrial-scale batteries.
Our tech stack and toolset are straightforward: Go, Python, Ruby, PostgreSQL, TigerData, dbt, Dagster, Grafana, Terraform, and self-hosted plus cloud compute. We keep meetings to a minimum to provide at least five hours of uninterrupted coding time per day. We conduct code reviews and apply both automated and manual testing. Our web apps and platforms are often deployed multiple times per day.
Return has offices in Amsterdam, Berlin, Brussels, Hamburg, Munich, Madrid, and Stuttgart. We are very open to remote work as long as you live in the EU. Our hiring process is swift but thorough: a brief call to get acquainted and discuss finances, followed by one or more technical interviews, and a paid visit to Amsterdam to meet the team.
The tech team members have co-founded several companies and have worked with remote development teams since 2008, and they will personally guide you through most of the recruiting process (there is no recruiter involved).
We aim to hire you in February or March ultimately.
xdof | Robotics Engineers, Infra Engineers, Product Engineers, GTM | SF Bay preferred, NYC & Remote possible for non-robotics roles
At xdof, we're at an inflection point. Frontier labs are racing to build general-purpose robots, and high-quality training data is the bottleneck. We're building the foundation behind the foundation models – the data collection systems, operational capability, exabyte-scale data warehouse, and software toolchain – to help our partners drive the field forward.
Founded by UC Berkeley Robotics PhDs and MechEs, this is a team that executes across software, hardware, and operations faster than I can believe sometimes. This speed and ability to deliver has led to partnerships with many of the top players in the space.
We are not quite yet out of stealth, so not able to share more details here, but are so understaffed relative to demand that I'd like to start semi-public hiring ASAP.
We’re building an AI system for analysts and scientists, based on a fundamentally new approach to reasoning and knowledge representation. Our approach differs from LLMs in that we compose algorithms symbolically to represent complex knowledge, and perform probabilistic computations. This enables the AI-driven application of statistical models to different problems, while providing the user with a verifiable reasoning path, and an assessment of the uncertainty in each answer. We are developing applications for analysis and research in domains such as Finance, Strategy Consulting, Engineering, and more.
This is a chance to shape a new approach to knowledge representation from the ground up, working alongside a collaborative team driven to solve hard problems.

MiLaboratories | Bilbao, Spain | ONSITE | VISA SPONSORSHIP | RELOCATION SUPPORT
We are MiLaboratories, the team behind Platforma.bio & MiXCR. We are building the "OS for Biology"—a platform that processes terabytes of genomic data to accelerate biological discovery and drug development.
We are a deep-tech research lab, not a typical SaaS. We work fully on-site in Bilbao because the complexity of our problems (high-performance computing + biological nuances) requires high-bandwidth, in-person collaboration.
We are hiring for three core roles:
1. Senior TypeScript Engineer (Desktop Platform / SDK): This is not a dashboard or a simple web GUI. You will build the architecture of our Desktop Platform—a high-performance local application that acts as the "OS" interface. You will deal with complex state management, massive data throughput, and bridge directly with our high-performance Rust data layer. We need someone who treats the browser engine as a runtime for heavy applications, not just for websites.
2. Senior Go Engineer: You will build distributed systems for high-load genomic data processing. This is not CRUD. We need someone who understands memory management, concurrency, and algorithmic efficiency at scale.
3. Bioinformatics Developer (Antibody Discovery): You will work on the scientific core, developing production blocks for NGS data analysis and antibody structure prediction. You should be fluent in both code and biology (Builder profile, not just analyst).
The Offer:
Comp: Top-tier EU salaries (~€90k - €120k).
Tax Advantage: Bizkaia has independent tax autonomy. You qualify for the "Special Impatriate Regime" (30% salary tax exemption + expense deductions).
The Reality: Your effective tax rate drops to ~15-20%, yielding a significantly higher net income than London or Berlin.
Stock: We grant ESOP and treat equity as a life-changing wealth vehicle, not a "nice to have."
Relocation: Comprehensive "Soft Landing" package (Visa, temporary housing, school search).
Location: Bilbao is a hidden gem—ocean, mountains, and high quality of life with a low cost of living.
Process: No HR screening. You will talk directly to the engineering team.
Email me (I am the CEO): stanp@milaboratories.com. Please mention "HN" in the subject and include your GitHub.

The demand for trusted digital ID is accelerating as AI deepfakes begin to destroy most of the ways we use to verify identity today. How private or secure is it to hold your driver's license or passport up to a webcam to get a bank account? Was it ever private or secure? Stable diffusion can break so much of this already. Society will need trusted digital IDs and credentials. Our mission is to allow them to be controlled by individuals, with safeguards to prevent descents into surveillance states and checkpoint societies.
We are the main implementers of category-defining initiatives such as the digital ID program for the California DMV, and the verifiable digital credentials program in Utah. We are private sector participants in NIST's National Cyber Security of Excellence initiative for privacy-preserving digital ID.
We are hiring skilled engineers who care about making a real impact in improving public services, digital autonomy, and user privacy for the world. We work closely with public sector agencies, and have high regard for public servants. We have a strong engineering and customer-oriented culture, and are not simply a SaaS product or AI wrapper. Our roles are not for the faint of heart: you will be expected to work hard and learn a lot in this role.
Our engineers are ambitious to get outcomes for our customers and their constituents. On any given day, they may write great Rust/C#/TypeScript, deal with mainframe dumps, read policy documents, respond to technical RFIs/RFPs, manage on-prem environments, implement new NFC + Bluetooth protocols in Swift/Kotlin, create CI/CD processes that enforce W3C accessibility guidelines and i18n requirements, rewrite lost specs from disassembled binaries, figure out stablecoin payments, and design new protections for public key infrastructure. It is a team effort, and people with T-shirt shaped skills are able to collaborate and learn a ton from each other every day.
We are interested in candidates who want to be proud of the meaningful impact they make for society, even if it takes time to get right. This is not the right job for someone who wants to "join a cool new AI startup" that implodes or exits in under a year.

We’re hiring an Enterprise AE to scale Parabola, a product used by finance and ops teams to automate messy, high-stakes workflows without needing engineers.
Parabola sits at the intersection of AI, automation, and real operational pain: unstructured data (PDFs, emails), brittle processes, constantly changing rules, and teams that can’t wait months for IT. Customers get to see live workflows in action immediately.

Engineers can't keep up with their production environments: dozens of services, dashboards everywhere, alerts firing constantly. The information to diagnose most issues already exists, but finding it takes longer than fixing the problem. And the more AI-generated code ships, the more services get deployed by people who won't be around to debug them.
Cleric connects to your existing observability stack, autonomously investigates production incidents, and tells engineers what's wrong. We're well funded with years of runway, a small team of AI and infrastructure veterans in SF, growing quickly. Stack: Python, Go, LLMs, Kubernetes.
Some of the problems we work on:
There's no test suite in production. When the AI says "the root cause is X," how do you verify that? You can't A/B test diagnoses. Ground truth labels don't exist. We build evaluation systems that track resolution outcomes over weeks and correlate fixes with diagnoses to build statistical confidence.
When something breaks, everything looks broken. Database latency spikes, five services throw errors, CPU goes up, logs explode. When an agent sees 47 anomalies at once, it needs to figure out which one is the root cause and which are symptoms, across systems with feedback loops, hidden dependencies, and non-obvious temporal relationships.
A single investigation might need six hours of metrics across 50 services, 10GB of logs, 10,000 distributed traces, the last 30 deployments, and the relevant runbooks. LLMs have finite context windows. What's relevant isn't known until you investigate. Getting retrieval wrong means wrong conclusions or exploding costs.
We're hiring:
- Staff Software Engineer, AI: You build the core agent. Reasoning, evals, self-improving feedback loops. You debug agent behavior by tracing reasoning and tool choices to understand why the agent made a specific decision. You build the systems that make a non-deterministic agent reliable, and push it to handle increasingly complex incidents.
- Staff Software Engineer, Product: You define what an AI SRE should actually be. When AI handles the reasoning, how do engineers stay sharp for cases it can't handle? How do you build trust when someone needs to verify agent conclusions at 2AM? You answer these by embedding with customers during real incidents, running experiments, and making the technical calls to ship what works.
- Software Engineer, Backend: You build and scale the investigation platform alongside our senior engineers. Integrations with Datadog, PagerDuty, and dozens of observability tools. Agent reasoning pipelines. Runtime systems that handle real-time data streaming at scale. You'll ship customer-facing functionality across the stack.
- Founding Marketer: Software engineers are allergic to AI hype. Our users already love the product. The challenge is reaching the next thousand teams without setting off their BS detectors. You build the marketing function from scratch: programs, pipeline, infrastructure. You need a technical foundation and the ability to hold a 30-minute conversation with a platform engineering lead without getting lost.
- Staff Designer (Remote): The interfaces for AI agents don't exist yet. How do you make autonomous reasoning legible without overwhelming? You own design across brand, product, and marketing, defining the visual language for a new category.

This is the case for the vast majority of companies posting jobs here and elsewhere (e.g., LinkedIn) right now. I've been looking for the past 7 months after a lay-off and that exact reply is the most common response I've seen (because it's an automated response). Well, most common after not hearing back at all, of course.

MixRank (YC S11) | Software Engineers | 100% REMOTE (Global) | Full-Time MixRank processes petabytes of data every month from web crawling. We have hundreds of customers using our data products including Google, Amazon, Facebook, Intel, and Adobe, across industries including Finance, Recruiting, Sales, Marketing, and Security. We’re a fully-remote company with a global footprint in over 20 countries. We're growing, profitable, employee-owned, no dependence on outside funding. Applicants from all geographies and backgrounds are welcome.
We are looking for passionate individuals for whom programming is not just a job but it’s something they love to do. We're obsessed with computers, programming, big data, databases, compilers, hardware, math, data science, and the internet. Does this sound like you? Please apply to join our team.
Our code base is very friendly to new contributors. You'll have a fully-functional development environment within hours (fully automated) and be pushing commits on your first day. Deployments to production happen multiple times per day and finish in less than 2 minutes. Effectively all of our codebase is written in Python, Rust, SQL, Javascript/TypeScript, and Nix. The core technologies you'll need familiarity with to be productive are Python, PostgreSQL, Linux, and Git.
We operate at a larger scale than typical startups. We operate two datacenters with high performance servers we've built that are capable of dealing with the volumes of data we process. We've implemented our own distributed file system. We do full-scale web crawls. We download and perform static analysis on the entire universe of Android APKs and iOS IPAs that are published. Unlike a typical startup where you'll spend half of your time in meetings, and the other half fixing bugs from Jira tickets— at MixRank you'll get to challenge yourself with difficult technical problems that will help you to grow as an individual.
We're hiring continuously for the positions below— they aren't singular positions that will close once filled. Our philosophy on hiring is that the candidate is more important than the position. For each new member of the team, we design a custom role and responsibilities that are specialized to their interests. Other companies will come up with a long list of specific requirements for a position with the expectation that you'll exactly replace someone from the team, or that you'll be the perfect tetris piece that satisfies the job requirements decided by a committee. MixRank is more pragmatic: we'll first get excited about having a unique individual on the team, then we'll figure out the best way to accommodate their specific talents.
We're looking for remote junior engineers that have 0-3 years of professional experience in software, and 5+ years of curiosity exploring computers, programming, and technical hobby projects. This is an open-ended entry role with mentorship and diverse opportunities to work on all areas of our product: databases, distributed systems, infrastructure and tooling, data analysis, machine learning, frontend/backend web development, APIs, data mining, data modeling, and more. To stand out, please highlight what makes you unique: passion for computing, curiosity and side projects, work ethic, niche research, etc.
Ideally you've already graduated, but if you still have one or more years left of school, please feel free to apply anyway, and if you're the right fit for the team we'll figure out a way to accommodate your schedule. https://www.ycombinator.com/companies/mixrank/jobs/Fnwsojk-j... --

Evercred (Pre-A stage) | Remote (US) | Technical Co-Founder - AI Agent Infrastructure | $20K/mo + up to 20% equity
We're building AI agents that reduce physician credentialing from 90 days to 14 days. $50B market, healthcare orgs desperate for this solution.
THE ROLE: You'd own agent orchestration, monitoring, and ML operations as founding technical leader. We have agents built by external agency launching in 2-4 weeks. You'd evaluate their implementation, build operational infrastructure, and own the technical strategy as we scale from 0 → thousands of verifications monthly.
THE OPPORTUNITY: - 20% equity (founding team level, 4-year vest) - $20K/month cash (adjustable based on equity preference) - Clear path to Series A: $1M ARR by summer 2025 - Own agent infrastructure for industry-disrupting product - Work directly with CEO/CPO, high autonomy
THE REALITY: - 3-4 month runway (aggressive growth targets) - Remote/async-first, US-based for timezone overlap - Paid trial week ($1,400) - mutual evaluation for partnership - Need production ML/agent experience - Must move fast intelligently (AI-assisted development expected)
THE TRIAL: Week 1: Evaluate third-party agent code, build monitoring infrastructure, or pivot to corrective strategy if code needs work. Testing judgment + execution + communication.
LOOKING FOR: - Production experience with LLM agents or ML systems - Can leverage AI tools (Claude/Cursor) to accelerate safely - Comfortable with ambiguity, short runway, high ownership - Wants equity upside, sees potential in healthcare transformation - CTO-level strategic thinking
NOT A FIT IF: - Need structured W2 role with benefits - Want low-risk established company - Optimizing for maximum cash vs. equity potential - Need multiple approval layers for decisions
TO APPLY: Email mark@evercred.com with: 1. Your approach to the trial problem (3-5 sentences) 2. Why 20% equity interests you vs. full cash 3. How you'd use AI tools to accelerate the week
We respond within 24 hours. Strong candidates start immediately.
Healthcare credentialing is broken. Help us fix it.
Translation: Vibe coded solution works great on demo, fails in prod. Freakishly hard problem. Fix it for us real quick, we may or may not pay you. Or just tell us how to do it, yeah that's much easier actually.
Not at all...please don't misinterpret and make poor assumptions. We are building AI agents to work with credential verification using a company that specializes in building AI agents...your interpretations is VERY far off the mark. Our founder is an emergency medicine MD who has raised directly from physicians and we've got real early traction. I do hope we can get some actual thoughtful applicants, thanks for the earlier reply self-selecting out :)

Sent an email out just a bit ago! Please let me know if it doesn't arrive for whatever reason.
EDIT: Looks like my comment was detached from its thread (https://news.ycombinator.com/item?id=46857847) without a comment explaining why. It's not breaking any of the stated rules at the top, and it seems like it would be common sense to let someone know they should expect a message (especially considering how temperamental email filtering can be these days). If this _is_ against the rules, I'd appreciate it if future hiring threads stated as such so that people like myself that have been trying to find a job for 7+ months can stop wasting our time here. I understand how it can be challenging to moderate a forum like HN, but the moderation priorities seem pretty disappointing, unfortunately.

Small boutique consulting | Remote (US) (some est meetings) | part-time/flexible/1099
Hi! I work with a small group of developers doing custom software development and consulting for small/medium businesses.
We are seeking a developery-data person with experience specifically with CloudSuite Distribution by Infor for one of our clients. It may be a bit of a shot in the dark, but if you have worked with this *specific* ERP system before, we'd be eager to talk to you. Reach out at "ekib.eikooc@rofni".reverse() Please include your experience in your email body/subject as we will have to quickly triage out most of the spam.
PS. Each time I post here I get ~500 emails, almost all are low effort that don't meet anything I am looking for, sometimes for months in the future. I expect it to be even worse as LLMs gain traction. I've hired 4 people from past posts (check my history if you want!), but it can take some time dig through everyone so I apologize to legitimate interests.
Just wanted to mention it was nice to see such a down to earth posting. Unfortunately, I've never even heard of the ERP you mentioned, but you sound like a good company to work for :-)
Infor is huge in the ERP space and dates back to bigger iron days(mainframe and midrange - IBM AS/400). They acquired a lot of smaller players over the years which might be way they are somewhat unknown these days unless you date yourself to that era.
Oh huh ... I actually did a lot of AS/400 & Stratus work back in the 80s. So Infor isn't written in RPG is it? the 400 actually had a decent COBOL compiler but everything seemed to end up in RPG :-/
I have used Infor. i have not administered it.
This is a wholesome job post. Reminded me there’s a human somewhere in the loop. I hope you find the right person.

Fusionbox | Python + TypeScript Engineers | United States| Full-time | REMOTE (Legal to work in the US)
We're a software engineering consultancy that builds enterprise software the right way. We negotiate the right to open source all our client code, maintain a handful of popular libraries, and our engineers contribute to Django core. We sponsor PyCon, DjangoCon, and Django Girls because we're invested in the ecosystem we build on.
We're looking for software engineers who value software design, system architecture, and collaboration. You should be comfortable with about half of these areas and eager to learn the rest: web application security, relational database design (PostgreSQL, beyond "SELECT *..."), Django internals, React, and distributed systems. What you'll actually work on: complex state machines for financial workflows, multi-tenant architectures with row-level security, custom database functions when the ORM isn't enough, and React frontends that handle real-time data without being a mess of useEffect hooks.
We're a small team where you'll own features end-to-end (database design to React components) and have opportunities to shape technical decisions. You'll get paid to write source code with a team that practices empathy and values work-life balance. If you've ever wished your job involved more elegant state machines and fewer marketing landing pages, let's talk: info@fusionbox.com.
Fusionbox: Leet-code style interview where you'll be expected to write correct, then optimized code in three different languages while a team of four watches. Owner calls it "pair programming."
ya. As a told a young friend of mine, I don't think I could even take a test anymore.

Charted Sea | Senior Product & Platform Engineer | REMOTE | Full-time Location: Hong Kong https://chartedsea.com/about
Charted Sea is a small, bootstrapped SaaS company helping customers scrape very complex platforms such as Shopee (a major e-commerce platform in Southeast Asia). We focus on hard technical problems (anti-bot, browser automation, fingerprinting, captcha solving).
We are hiring a senior engineer to take ownership of our core platform: scraper orchestrator, billing & payments, customer dashboard, and parts of our AI-based captcha tooling. This is a hands-on role with real ownership: architectural decisions, setting standards, and gradually mentoring other engineers. The role is very full-stack (infra, backend, frontend).
Stack includes TypeScript (most backend & web), Rust (new backend services, migration in progress), Go (Android scraper), PyTorch (captcha solvers), PostgreSQL, Redis, GitHub Actions, Ansible, Ubuntu Linux, bare-metal Hetzner servers.
We are profitable, demand is growing fast, and engineering bandwidth is the main bottleneck. Team is small (3 engineers), fully remote, mostly async (we expect ~4h overlap with UTC+8).
Compensation: $80k–$120k USD base (depending on experience) + monthly bonus tied to company revenue (10% of net revenue shared with employees).
Apply by emailing marc.plouhinec@chartedsea.com with a short intro and CV/GitHub. I'm the founder and will personally read and reply.
TextQL | Senior Software Engineer (FT) | ONSITE | New York City | $200k Salary - $400k Total Compensation
Company: TextQL is working to drive the unit cost of a data-driven decision down to zero. We're building the agentic data lakehouse – finding trustworthy answers to hard questions from messy enterprise data without configuring schemas, moving data, or lengthy implementation roadmaps.
Roles:
* Platform: today, no one stakes their job on AI-generated queries. You'll build the system that changes that—giving agents the context to query enterprise data correctly, and the guardrails to prove it.
* Infrastructure: sandboxes are not enough for agents to work with enterprise data. You will develop reliable infrastructure for the first data platform designed to be operated agent-first – ETL pipelines, Trino clusters, and systems that let agents spin up infrastructure on their own.
Stack: Go, Haskell, TypeScript, DuckDB, Trino, PostgreSQL, Redis, Kubernetes, AWS
Perks: 21 days PTO, free lunch, 5% 401(k) matching, top-tier health insurance, visa sponsorship
How to Apply: email gabriel@textql.com with the most significant technical challenge you have solved, GitHub if you have one, and LinkedIn and/or resume (PDF).

SEEKING PARTNER | Bay Area | Applied Research Lab
Not a job. I’m exploring alignment with a potential partner.
I’m a systems builder (CS/infra founder; shut down my last startup) who spent the past two years going deep on foundational math that most engineers (and I guess many mathematicians) tend to ignore, largely at an nLab level, because standard abstractions stop composing.
I’m working toward a small, private apply-focus lab to bridge native CS intuition (computation, scale, systems) with structural, information-theoretic mathematics. The focus is composability, learning, universality, and complexity, with the intent to build, not publish.
The approach is unconventional, but intentional: staying close to real systems while reworking foundations when existing methods stop composing.
Looking for a self-funded generalist comfortable crossing CS, math, and theory that's interested in structure, information, ethics, and long-horizon work.
I'm interested in chatting. Have a way to contact you?

MONUMENTAL | https://www.monumental.co/ | Amsterdam, The Netherlands | Full Time | Onsite
We make robots that autonomously construct buildings. We are currently developing and manufacturing our autonomous bricklaying system in the beautiful centre of Amsterdam. And our robots are already earning real revenue operating on construction sites all over the Netherlands.
We're looking for experienced software engineers for many roles. You can help us solve problems like:
- Data sync and analytics queries across a fleet of robots (that can be offline for hours at a time)
- Modelling buildings in code and finding the right UI for operators to edit them
- Designing systems for robots to drive safely and fully autonomously around a building site
Check out the progress we've already made on Atrium, our operating system for robotics: https://www.monumental.co/atrium
We're rapidly scaling up operations and we need experienced engineers who can build the systems that manage all of that complexity. If you think that 'full-stack' could reasonably mean debugging firmware, mixing buckets of mortar _and_ writing React components, we are looking for you. Robotics experience not required!
https://www.monumental.co/jobs
Would you hire US citizens willing to move?
Not OP, but Monumental is a registered sponsor for highly skilled migrants, which is applicable for the roles listed. So in short, if you got an offer you could be sponsored.
Thank you for sharing. I now also have a better idea of what wording to look for in the future.
Yes
Thanks!

Shinzo (https://shinzo.network)| USA/Canada + REMOTE | Multiple Full-Time Roles
We're building the read layer for blockchains. The irony of "trustless" applications depending on centralized indexers like Alchemy or The Graph isn't lost on us—we're fixing it.
Shinzo embeds indexing directly into validators, turning blockchain data into a cryptographically verifiable public good. No trusted intermediaries, no API keys, no "please don't rate limit me" prayers at 2am.

We care more about what you can build than where you went to school.

Integral | Full-Stack Developer | REMOTE (US)
I'm Stephen, founder of Integral. We're a fractional CTO firm for scaling businesses ($10M-$100M) drowning in SaaS sprawl, broken automations, and data scattered across 20+ tools.
What you'd work on: - Building unified dashboards pulling from Shopify, Stripe, HubSpot, and ad platforms (Meta, TikTok, Google) - Multi-system automations: HubSpot → SamCart → Klaviyo → Circle cancellation cascades - Custom web apps (React/TypeScript, Supabase) when off-the-shelf fails - Debugging/replacing complex Zapier/N8N workflows across client ecosystems - API integrations with whatever the client uses—we've touched trigger.dev, hubspot, asana, samcart, AWS, and many more this month alone
The role: You own your clients. Not "execute tickets"—actually understand their business, propose solutions, join calls (only when needed.) Small team, high autonomy, direct founder access. We're integration specialists, not a body shop.
Stack: TypeScript, React, Python, Node, Supabase/Postgres, REST APIs — end to end. Bonus points if your execution is deeply engineering-driven.
What we're not: Big tech process, Jira hell, or "ticket monkey" work. We move fast on real problems for real businesses. However, that does not mean we aren't highly organized and efficient.
Contractor, ~20-30 hrs/week to start. US timezone overlap required.
stephen@gointegral.co — tell me about a messy integration you've fixed.
I worked on a messy integration where data moved across multiple systems and failures were silently cascading—broken retries, duplicated records, and zero visibility into where things went wrong. I mapped the full flow end-to-end, added idempotency and clear boundaries between systems, and replaced brittle chained logic with a more explicit, observable integration. That cut down failures immediately and made the setup easy to extend when new tools were added. This kind of work—owning real systems and untangling messy automations—is exactly what I enjoy.

Hi tim.
From talking to the hiring bot (cool tool!), It seems there's a list of countries that Posthog can't hire from for different reasons. If it's ok with you, I'd like to know if this list is up to date.
And for me specifically, I live in Argentina and some weeks ago I sent an application but I think that the resume might have been a bit hard to follow (I now updated it). Is it OK to re-send the application or are decisions for the same role final?
Thank you. Have a great day.
would love to scale posthog as a PM: https://www.linkedin.com/in/satyamvdave/
Very cool on the transparency! I was surprised to see Spain (all one bucket) has higher salaries on your calculator than places like Edinburgh.
We have a lower bound on our location based pay which is a percentage of salary in SF, which applies to both those locations. We fixed the currencies a while ago (so people's pay don't fluctuate up and down in local currencies), which is why those two locations have different pay now.

Hey HN - I'm George, founder of xFigura. We're building the AI-native creative canvas for architects - Figma for the built world.
The problem: Architects design where you live, work, get surgery, send your kids to school. Their tools? AutoCAD (1982). Revit (2000). The physical world runs on software older than the iPhone.
Six months in, we have 5 of the top 20 architecture firms using the product. No marketing, $0 to $1M ARR in less than a year, and we just closed a $3M seed round.
What we're building: AI orchestration across 50+ generative models, infinite canvas collaboration, native CAD integrations (Rhino, Speckle, Revit), enterprise RAG for firm-specific knowledge.
Stack: DynamoDB, Next.js, Tailwind, AWS, FastAPI. Looking for someone who's shipped production AI systems and is in the 99th percentile of using AI in their own workflow (Cursor, Claude, etc.).
Small team, huge ownership. You'd own entire systems, not tickets.
Email me directly: info@xfigura.ai (mention HN in Subject)
Count | Senior Software Engineer | REMOTE (UK/Europe/US East Coast) | Full-time | £100–140k (or local equivalent) + Equity | https://count.co
Count is an infinite, real-time canvas where SQL, Python, and low-code query cells live side-by-side with visualizations and freeform whiteboarding. It replaces the traditional linear notebook with a collaborative space for modeling, analysis, and presentation.
Under the hood, we've built a custom WebGL rendering engine, data visualization library, graph-based modeling layer, and horizontally scalable compute engine (DuckDB-based) that dynamically shifts execution between browser and server to minimize latency and reduce database load.
You'll help evolve the core platform: integrating agentic workflows into data exploration, pushing the performance limits of our distributed execution layer, and building powerful new analytics experiences used daily by customers. You'll have high autonomy and ownership over major parts of the product and technical roadmap, from architecture through production.
Tech stack: TypeScript, Python, Node.js, WebAssembly, WebGL, Apache Arrow/Parquet, DuckDB, Kubernetes, React.

Zed Industries | North America, South America, Europe REMOTE | https://zed.dev/ Zed is a company for developers, by developers. All 3 of our founders have spent years in the trenches writing software and still do it almost every single day. We know the only way to build the world's best code editor is by equipping every single member of the team to do the best work of their career.
We've raised $42M to support our ultimate vision, a new way to collaborate on software, where conversations about code remain connected to the code itself, instead of being tied to aging snapshots or scattered across different tools. The first step was creating a high-quality editor to serve as the user interface. Now this new investment lets us expand to tackle the next phase of our plan. We're developing a new kind of operation-based version control that incrementally tracks the evolution of your code with edit-level granularity, and we're integrating it into Zed to make collaboration, both with agents and teammates, a first-class part of the coding experience.

DoStuff | Retention Product Engineer (Full-Stack) | Austin or Remote (US time zones) | Contract to hire preferred
I’m Scott - founder of DoStuff. We have a pretty big, and growing, membership product called DoMORE - $7/month for a pair of tickets to an event we think you’ll like. We’re hiring a hands-on Retention Product Engineer to own engagement → churn reduction end-to-end.
You will analyze cohorts, define the retention north-star metric, ship product and lifecycle experiments yourself, and measure impact.
This is not a PM-only role and not a pure engineering role. You own the full loop: insight → build → measure → iterate.
Our stack: React (FE), Ruby on Rails + Elixir (BE), Postgres, Elasticsearch. Proprietary lifecycle tooling for email, SMS, and in-app (web). No feature-flagging or experimentation framework yet - you’ll help install the remaining plumbing.
Retention is the highest-impact opportunity in the business and this role has real authority to ship.
If you have experience with the above and this sounds like fun, reach out to scott+domore@dostuffmedia.com with something in the subject line that let’s me know you’re real and interested. THX

59K for a senior fullstack engineer in Hamburg is crazy low.
I agree that more would be better. The position is grant-funded and the grant has strict rules on funding limits.
Someone might join if they are desperate enough and hop at the next better opportunity, that's what I would do. Aren't you worried this will be a waste of time?
Anybody surprised that the tech sector in Germany is in the state it's in?
Jobmarket in Germany is currently crashed; most people would be happy to get an offer for "only" 60k
Definitely not true for full stack developers with more than 1-2 YOE
If you lose your job right now, expect a minimum cut of 20-30%

Despite being something everyone does, gifting is one of the areas of commerce yet to be disrupted, and we're working on building the best and most delightful product in this space.
Our product is used by Google, Stripe, Anthropic, Meta, NBCUniversal, Notion, and others, and we also offer a developer API for commerce. Tech stack is Ruby + React + TypeScript, though we're flexible on backend language if you know Python or Node.js better. All roles are full-stack.
We're coming off of a big year and planning for scale in 2026. We have a few new roles to accelerate our growth.
• Staff Software Engineer ($200–250K) — for those who ship at a startup pace and have a great eye for detail
• Senior Software Engineer, Customer Engineering ($150–200K) — if you like to hear a customer request in the morning and tell them it’s shipped in the afternoon. US and Canada only for this one
• Senior Software Engineer, Growth ($150–200K) — be the engineer who has the most direct impact on our growth
• Data Analyst ($80–140K) — build models to help power decision-making across our business (not a dev role but thought I'd include it)
We're looking for people who have great startup energy, want to win, and bring great vibes to our tight-knit team. Great time to join since our offsite in London is happening soon (we're US-based, this is our third international offsite).

Apparently I can’t attach a cover letter, but I think I might be a better fit than might be obvious from my résumé. I do tend to "think like a product owner" (to quote the job desc) and love learning new tech on the job; I have been a React fan since 2014; and I know a dozen languages, so picking up Golang sounds fun.

CareIgnition | Senior/Staff Software Engineer (Generalist) | REMOTE, Chicago (US Only) Medical billing in America is a black box of fragmented data and inefficiency. At CareIgnition, we are building the transparency layer for healthcare. We transform massive, messy datasets into financial clarity for employers and providers.
We are looking for a pragmatic generalist. You’ll be working across the entire stack: from building customer-facing features in React and Django to architecting data pipelines that process petabytes of medical claims and rates. Crucially, this role involves deep algorithmic and analytical work. You won't just move data; you will implement the logic that makes sense of it.
We value "generalist" DNA—engineers who are as comfortable optimizing a SQL query as they are building a clean UI component. If you enjoy solving high-scale data problems that have a direct impact on healthcare affordability, we’d love to talk.
Tech: Python, Django, React, AWS (ECS, Step Functions, Athena), SQL (DuckDB/Polars), Iceberg/Redshift.

Veho | ONSITE / HYBRID 3 days per week | NYC or Boston | No Visa | https://shipveho.com/careers
Hi there! At Veho, we don't sell software. We ship packages. Lots of them. We have all of the interesting problems that crop up when running twinned distributed systems in AWS and the real world. It's pretty great.
We're hiring staff-level folks (L4+) in NYC and Boston: Data Scientists, Data Engineers, Mobile Engineers, and Backend Engineers (typescript).
Personally, I'm hiring a Staff Data Engineer with the depth of experience to be a technical lead and mentor for the Data Platform team, while also shipping code. You will need to understand distributed data systems both intellectually and at an instinctive, emotional level. You should have Opinions about the wild boar book. You should probably also be comfortable writing and debugging English, SQL, and Python.
If that sounds like you, I really want you to apply for the Staff Data Engineer role on our career page. Our inbound applications are reviewed by humans.
With apologies that our first interaction requires this silliness: including one of the 7-digit numbers from the "ROS Calculator" on Veho's website in the appropriate box will heavily bias me towards believing you are a human being. That's more of an advantage than it may seem! It's worth the thirty seconds. It would also speed things along if you populate the "Location" field to confirm you are aware this is an in-office role.

Kinelo | kinelo.com | Full-Stack Engineer (AI + Backend) | San Francisco | Onsite
Kinelo manages the new type of hybrid team that will emerge in the future: humans+AI working shoulder-to-“shoulder”.
Our first product helps human software engineering teams deliver more efficiently and more reliably by assisting in coordination and engineering management. But it’s built on a foundational layer that ingests data, knowledge, and process across communications and systems, exposing that to humans and AI alike.
Eventually, Kinelo will become a proper human+AI orchestration layer, managing entire companies, and our goal is to have Kinelo run Kinelo (we already dogfood it today).
We’re looking for high ownership individuals to join our small team and shape its direction. We also just opened a new SF office and new hires will have the ability to help shape company culture, engineering practices, architecture, and roadmap.
We’re well-funded (just raised another round), founded by a serial founder, anti-bureaucratic, and highly technical.
We’re looking for:
- Those who want to go 0 to 1 with high ownership: moving features and products from idea on a napkin, to prototype, to engineering UI, to shipped and polished product
- ~8 years professional experience, including the pre-LLM days with strong CS fundamentals
- A balance of wisdom from experience and optimism about the future
- Strong TypeScript and Postgres (or other RDBMS) experience at scale and with high reliability (SaaS apps, APIs, etc)
- Experience with a variety of technologies, including containerization, distributed systems, and at least one strongly typed programming language (Go, C++, Java, etc)
- Ideally experience with ML and AI systems (though expertise in ML, data science, etc is not needed for this role)
We can’t sponsor visas but relocation assistance to SF is possible.

Hack Club | Quality & Integrity Lead, YSWS | Shelburne, Vermont (USA) | ONSITE
Hack Club (https://hackclub.com / https://github.com/hackclub) is a nonprofit where 1,000s of teenagers ship real projects — games, hardware, websites, apps — and we send them free stuff in return. 100k+ teens, 140 countries. Our motto is "by teens, for teens" and we operate with radical trust and transparency.
Every month, thousands of projects come through our You Ship We Ship programs. Program authors do the primary reviews. We need someone to QA the reviewers — a second set of eyes who can tell us: are they making good calls? Catching the fake projects? Being too harsh on legitimate ones?
Responsibilities:
- Spot-check approved projects (random sampling)
- Audit reviewer consistency and catch patterns
- Define what "high quality" actually means and document it
- Train program authors to make better decisions
- Handle appeals and investigations
- Build systems that work at 100k projects/year
You'll still do plenty of hands-on review — you can't spot-check effectively without understanding the projects deeply. But your mission is ensuring the integrity of the entire process, not being the bottleneck for each submission.
$55-70k. 4 weeks PTO. Health/dental/vision. Based in an 1800s building in Shelburne, Vermont. Full details: https://hiring.hackclub.com/38523

Puma.tech | Remote-first with PST overlap | iOS/MacOS, Android, Ai/ML, Growth | https://puma.tech
Hi all, I’m Yuriy, founder of Puma.tech. Previously worked as software engineer & developer advocate at Cloudant (YC S08, Acq. by IBM), Meteor (YC S11), Parse (YC S11, Facebook/Meta), and explored AI/ML (computer vision for self-driving cars).
We have two products:
1. Puma Browser (iOS & Android) – browser with built in LLMs & Wallets. Private by design.
2. PumaAI app for Mac – ChatGPT/Atlas, but with ability to pick different model providers and fall-back to local-first ones for data privacy.
Open Roles: Eng (iOS/MacOS, Android, Ai/ML, Browser Extensions), Based Social Media Intern; Internships: Eng, Design, Growth
We’ve raised a few rounds from some of the best builders in crypto and ai:
Protocol Labs (YC S14), Chris Larsen (Ripple), Anatoly Yakovenko (Solana), Illia Polosukhin (NEAR Protocol), Sridhar Ramaswamy (Snowflake CEO, Neeva, Greylock), Jason Warner (poolside.ai, ex-GitHub CTO), Don Ho (Orange DAO, Quantstamp W18), Evil Rabbit (Vercel), John Phamous (SF Compute) and other amazing builders.
How to Apply: email careers+hn [at] puma.tech with your GitHub, a note on what you're most proud of building and what you'd like to build next.
Thank you!
Language REACTOR
REMOTE mostly, but I travel often (Europe, Asia) and it's good to work in person time to time.
We make software for learning languages. The focus is on making tools, rather than content. But actually, the line between code and content is blurring with LLMs.
I am the main coder on the project and I'm looking for a coding partner to help spread the load and allow more ambitious scope. Project is solid financially.
Most of the codebase is fairly decent Typescript. Backend knowledge a plus.
I need someone with sound judgement and taste that can plan and execute independently, but that also can communicate and coordinate complex changes well. Ingenuity and resourcefulness.
I use Claude/Cursor extensively.
I'm quite interested to hear from you if you have a project that overlaps in scope with Language Reactor.

Trunk | https://trunk.io
Developer Marketing Lead - Remote friendly | Senior DevRel Engineer - San Francisco| Technical Lead (CI & Test Data Platform) - San Francisco | Sr Platform Engineer - San Francisco
Trunk is an a16z funded (25M) Series A dev tools startup, redefining software development at scale. We've helped engineerings teams at: Google X, Zillow, and Brex to understand why their builds fail, which tests are flaky, and how to ship code faster without sacrificing reliability. AI has made writing code 10x faster, but shipping is still painfully slow. The bottleneck has shifted downstream - to merge conflicts, flaky tests, inconsistent code quality, and dozens of other frictions that drain productivity and morale. Engineering teams that can stay focused on designing, implementing, and delivering software will build magical, high-quality projects - and they'll be happier doing it. We're building a CI Reliability Platform that empowers teams to land code faster and develop happier!
Our products:
Our tech stack:Frontend: Typescript, React, Next.js, AWS Backend: Typescript, Node, AWS Data pipelines: Dagster, Python, polars CI/CD: GitHub Actions
Unlimited PTO (and we all actually take PTO), competitive salary and equity packages! Please apply here: https://trunk.io/jobs.

VIVA Finance | Atlanta, GA (In Person)| Back-end Software Engineer
Target Experience Level: 2-4 years of professional software experience
VIVA is a Fintech Startup based in Atlanta, GA with the mission to build a more inclusive financial system. VIVA offers unsecured personal loans to customers who have traditionally been excluded and taken advantage of by legacy financial institutions. The VIVA difference is to underwrite heavily on employment history and set up repayments through voluntary direct deposit payments from the borrower's paycheck. Our interest rates are less than 1/3 of the rates our customers are able to get from other financing options.
We are a VC backed company and have been in business for 6 years. We have been profitable since mid 2024 and are dramatically ramping up origination volume in 2026. We are hiring an additional backend engineer to support the larger transaction volume, as well as to support new products we are launching to diversify our revenue stream (including automobile refinancing and a credit builder account). You will join our engineering team of 11 and work in a dynamic environment where you are frequently writing net new code to directly support business objectives.
Our tech stack for the back-end is fully on AWS, using Lambda and ECS for compute and Typescript as the language, but experience with this specific stack is not necessary for talented candidates. Our preference is candidates who can come in office 4 days a week to our office on the Atlanta Beltline (next to Krog Street Market). VIVA does not provide visa sponsorship, so please have authorization to work in the USA.
Send an introduction to our hiring manger (alexa@viva-finance.com) with a resume and we will be in touch!
Tiger Data (FKA Timescale) [ Global | 100% Remote | Multiple Roles: Eng, GTM, Support + more ] We began in 2017 as TimescaleDB, focused on making PostgreSQL the best database for time-series data. As our customers evolved, so did we.
Today, more than 2,000 companies use our technology to power real-time analytics, agentic applications, and high-ingest operational systems. What started as a time-series database has become the fastest PostgreSQL for modern workloads. To reflect that evolution, we’re now TigerData—a name that speaks to our speed, precision, and ambition. The tiger has long been part of our culture: fast, focused, powerful. From “Tiger Time” all-hands to welcoming new hires as “tiger cubs,” it’s how we build—decisively, fearlessly, and with purpose.
This is not a reinvention: it’s a reflection of how we already serve our customers today.
TigerData is growing! Check us out: https://www.tigerdata.com/careers

Partner Sales Manager, AWS - https://www.tigerdata.com/careers/c4980e2e-3b9e-4f97-9a2a-cf...
I use TimescaleDB every day.
Being able to ask questions to an LLM copilot about patterns across several billion rows, 140GB of time series data, like how the market reacts 15 minutes, 1 day, and 1 week after Federal Reserve press releases, using time_bucket() and other aggregation functions with compressed chunks, and having the copilot generate the queries and run them fast, is going to be game changing. I can ask to write a script to scrape the press releases, to run them through another agent to classify them (hawk, dove) and use that information in the time series analysis.
Even though that exploration has not produced any actionable, tradable results for me, which is why I am sharing it, eventually TimescaleDB will be one of the most important tools in fields like medical research. A researcher will be able to ask in natural language for statistically significant patterns in the data, and LLM agents will query it quickly while taking advantage of all the TimescaleDB optimizations.
G'day! There seems to be a major inconsistency in the listing for https://www.tigerdata.com/careers/ac8ae587-fd1d-4a3f-b844-74.... While the job description mentions "4-day 10-hour night shift from 7am - 5pm IST (1:30am to 11:30am UTC) Friday-Monday", the questionnaire for submission mentions "4-day 10-hour night shift from 11pm - 9am IST (4:30pm to 2:30am UTC) Friday-Monday". Might be worth rectifying.

We’re hiring for two founding engineering roles to work directly with us in our NYC office (in-person only):

Vidably | Founding Engineers and Designer | San Francisco (SF) | Full-time | Onsite
(I only have one JD posted publicly, but I'm hiring broadly for eng + design): https://www.linkedin.com/jobs/view/4330646312
I'm founder of Vidably and just closed a $1.5M pre-seed last week.
AI agents are about to orchestrate trillions in commerce, but today they shop on thin data: product specs, studio photos, and text reviews. Agents need evidence, not marketing. Today, the most influential product evidence lives on TikTok and Reels, outside the surfaces brands control and agents can use. Vidably puts verified buyer video directly onto e-commerce product pages through a lightweight widget. We capture that video post-purchase and link it to real purchasing outcomes. Every video is SKU-linked and structured so shopping agents can reason over it.
We're already seeing organic pull from creators and expansion from brands.

Upway | Software Engineers (All levels), Senior Product Designer, Senior Product Managers | Full-time | Paris (ONSITE)
We’re building the biggest second-hand bike shop in the world.
Upway is the leading marketplace for refurbished e-bikes across Europe and the United States.
In 3 years, we grew from 0 to $200M GMV. The tech team grew from a small senior core to ~12 engineers in 2025, and we plan to grow to ~30 engineers in 2026. We also raised a $60M Series C at the end of last year to support the next phase of the company.

We’re looking for engineers and product people who like tech as much as business, people who want ownership, enjoy making product and business trade-offs, and care about outcomes, not just systems.
We work with a Shape Up–inspired methodology that gives teams real ownership: shaping problems, building solutions, shipping, and learning from real-world impact.
Stack: TypeScript | NestJS | React | Shopify | PostgreSQL | GCP
Why it’s a great time to join:
- The organization is switching gears: bigger ambitions, broader scope, more responsibility.
- The challenges are growing with the team: product, marketplace, and operational complexity.
- High ownership environment where engineers influence technical and business decisions.
- Paris on purpose: at our current pace, working in person is a real advantage.

Level 12 | Full Stack Web Developer - Python, JavaScript, SQL | Mid-Level & Senior | REMOTE | SALARY:$95K-145K+ | https://www.level12.io/careers/
Level 12 is a software consulting and custom development agency. We have mid and senior level positions. Our job descriptions are written by developers for developers. No HR fluff here, we want you to know what you are really getting into:
https://www.level12.io/careers/
- We have a commitment to transparency and offer a "no surprises experience" throughout the interview and hiring process. We value candor...as evidenced by the length of our job description. :)
- Our CEO prefers the title CED, Chief Executive Developer. Engineering and operational concerns don't take a back seat when potential sales come to the front door.
- You will be working remote with a team that is all working remote and has been for years. Let's make the best use of our time by not commuting.
- We practice and preach sound development practices. You are likely to learn and grow as a developer while working here.
- You are committed to automated testing of all the software you write (our apps typically have 92%+ test coverage).
- We have a no-drama office policy. We value and cultivate enjoyable working relationships among team members. No jerks allowed!
- We emphasize work/life balance and adopt policies that make sure our people don't get burnt out. For instance, our PTO/Vacation policies are designed so that you actually use them.
- If you apply, we guarantee that we will give you a response, whether "yay" or "nay". No black holes here!
NOTE: our intent to hire is currently tentative but should be resolved one way or the other in the next couple weeks. So, if you are interested, read the job description but, for now, don't go through the entire application process unless you really want to. Just email me (the CEO) with a clean dad joke, or your take on Kirk vs Picard, and reference your interest: randy.syring@level12.io. I'll follow-up in a couple weeks when I know for sure if we are going to be taking applications.

> Thanks for posting! Are there specific language requirements, since the role is in the Japan office?
Well, can you understand the job posting? [1] It’s written in Japanese, so if you can’t read it, you’re probably not qualified to work in Japan. Some companies do hire non-Japanese speakers if your main goal is visa sponsorship to move here, but that’s not a great idea. You really need enough Japanese to get by, handle taxes, see a doctor, manage your bank account, and read emergency instructions in case of an earthquake or tsunami. It’s better to learn the language before you make the move.

Return | REMOTE | Software engineer backend (Go/Golang) | Full-time
Return (https://return.energy) is hiring a software engineer to work on platforms that accelerate the transition to carbon-free energy. Return’s main activity is building and operating industrial-scale Battery Energy Storage Systems. Our operations are located in the Netherlands, Germany, Belgium, and Spain. You will make a measurable, country-level impact on the transition to renewable energy. Return recently raised €300M to support its growth.
While we employ more than 120 people, Return’s technical team remains small with 13 members. Our platform automates processes in energy storage, monitoring, market optimization, sales, project management, procurement, construction, and customer service.
During the first three years of operation, we laid the foundation for our platforms, and we are ready to scale up. This is why we are looking for an experienced software engineer.
Your primary focus will be to further develop our battery virtualization platform, enabling customers to use slices of battery capacity distributed across our fleet of industrial-scale batteries.
Our tech stack and toolset are straightforward: Go, Python, Ruby, PostgreSQL, TigerData, dbt, Dagster, Grafana, Terraform, and self-hosted plus cloud compute. We keep meetings to a minimum to provide at least five hours of uninterrupted coding time per day. We conduct code reviews and apply both automated and manual testing. Our web apps and platforms are often deployed multiple times per day.
Return has offices in Amsterdam, Berlin, Brussels, Hamburg, Munich, Madrid, and Stuttgart. We are very open to remote work as long as you live in the EU. Our hiring process is swift but thorough: a brief call to get acquainted and discuss finances, followed by one or more technical interviews, and a paid visit to Amsterdam to meet the team.
The tech team members have co-founded several companies and have worked with remote development teams since 2008, and they will personally guide you through most of the recruiting process (there is no recruiter involved).
We aim to hire you in February or March ultimately.

We are developing applications for analysis and research in domains such as Finance, Strategy Consulting, Engineering, and more.
This is a chance to shape a new approach to knowledge representation from the ground up, working alongside a collaborative team driven to solve hard problems.

* Product Software Engineering (Quantitative Modeling)
* Bayesian Software Engineering
* Program Synthesis Engineering
* Technical Project Manager

MiLaboratories | Bilbao, Spain | ONSITE | VISA SPONSORSHIP | RELOCATION SUPPORT
We are MiLaboratories, the team behind Platforma.bio & MiXCR. We are building the "OS for Biology"—a platform that processes terabytes of genomic data to accelerate biological discovery and drug development.
We are a deep-tech research lab, not a typical SaaS. We work fully on-site in Bilbao because the complexity of our problems (high-performance computing + biological nuances) requires high-bandwidth, in-person collaboration.
We are hiring for three core roles:
1. Senior TypeScript Engineer (Desktop Platform / SDK): This is not a dashboard or a simple web GUI. You will build the architecture of our Desktop Platform—a high-performance local application that acts as the "OS" interface. You will deal with complex state management, massive data throughput, and bridge directly with our high-performance Rust data layer. We need someone who treats the browser engine as a runtime for heavy applications, not just for websites.
2. Senior Go Engineer: You will build distributed systems for high-load genomic data processing. This is not CRUD. We need someone who understands memory management, concurrency, and algorithmic efficiency at scale.
3. Bioinformatics Developer (Antibody Discovery): You will work on the scientific core, developing production blocks for NGS data analysis and antibody structure prediction. You should be fluent in both code and biology (Builder profile, not just analyst).
The Offer:
Comp: Top-tier EU salaries (~€90k - €120k).
Tax Advantage: Bizkaia has independent tax autonomy. You qualify for the "Special Impatriate Regime" (30% salary tax exemption + expense deductions).
The Reality: Your effective tax rate drops to ~15-20%, yielding a significantly higher net income than London or Berlin.
Stock: We grant ESOP and treat equity as a life-changing wealth vehicle, not a "nice to have."
Relocation: Comprehensive "Soft Landing" package (Visa, temporary housing, school search).
Location: Bilbao is a hidden gem—ocean, mountains, and high quality of life with a low cost of living.
Process: No HR screening. You will talk directly to the engineering team.
Email me (I am the CEO): stanp@milaboratories.com. Please mention "HN" in the subject and include your GitHub.
Plutus | Kirkland, WA (In Person) Founding Engineer | We're building a fintech platform that democratizes sophisticated investment strategies. We're looking for engineers who love the craft of software and take pride in what they build.
This is a hands-on technical leadership role where you'll architect and build scalable systems, establish engineering best practices, and help shape our technical culture. You'll own end-to-end delivery from conception to production.

4. Use AI effectively, but own the fundamentals - You leverage AI tools to move faster and be more productive, but you have deep knowledge of the entire stack. You can explain what the code does, debug when things break, and make architectural decisions without relying on AI to tell you what's right.

SpruceID (YC W21) | REMOTE (US-Based Preferred) | Full-Time | spruceid.com
[NEW ROLE FOR EXCEPTIONAL NEW GRADS OPEN]
Spruce lets users control their data across the web. Instead of users logging into platforms, we believe platforms should request to access data vaults controlled by users.
The demand for trusted digital ID is accelerating as AI deepfakes begin to destroy most of the ways we use to verify identity today. How private or secure is it to hold your driver's license or passport up to a webcam to get a bank account? Was it ever private or secure? Stable diffusion can break so much of this already. Society will need trusted digital IDs and credentials. Our mission is to allow them to be controlled by individuals, with safeguards to prevent descents into surveillance states and checkpoint societies.
We are the main implementers of category-defining initiatives such as the digital ID program for the California DMV, and the verifiable digital credentials program in Utah. We are private sector participants in NIST's National Cyber Security of Excellence initiative for privacy-preserving digital ID.
We are hiring skilled engineers who care about making a real impact in improving public services, digital autonomy, and user privacy for the world. We work closely with public sector agencies, and have high regard for public servants. We have a strong engineering and customer-oriented culture, and are not simply a SaaS product or AI wrapper. Our roles are not for the faint of heart: you will be expected to work hard and learn a lot in this role.
Our engineers are ambitious to get outcomes for our customers and their constituents. On any given day, they may write great Rust/C#/TypeScript, deal with mainframe dumps, read policy documents, respond to technical RFIs/RFPs, manage on-prem environments, implement new NFC + Bluetooth protocols in Swift/Kotlin, create CI/CD processes that enforce W3C accessibility guidelines and i18n requirements, rewrite lost specs from disassembled binaries, figure out stablecoin payments, and design new protections for public key infrastructure. It is a team effort, and people with T-shirt shaped skills are able to collaborate and learn a ton from each other every day.
We are interested in candidates who want to be proud of the meaningful impact they make for society, even if it takes time to get right. This is not the right job for someone who wants to "join a cool new AI startup" that implodes or exits in under a year.

Parabola Labs (NYC / SF) | Enterprise Account Exec | Full-time | On-site Hybrid
We’re hiring an Enterprise AE to scale Parabola, a product used by finance and ops teams to automate messy, high-stakes workflows without needing engineers.
Parabola sits at the intersection of AI, automation, and real operational pain: unstructured data (PDFs, emails), brittle processes, constantly changing rules, and teams that can’t wait months for IT. Customers get to see live workflows in action immediately.
This is not a traditional enterprise sale... Deals are driven by automations, as they are built live in-app. Customers engage multiple times per week and see value instantly. Expansion is natural because the product is horizontal, the first team is never the last
We’re looking for someone who loves going deep on product and customer problems. You can work comfortably with operators and execs (CFO/COO) as well as with companies in the retail/ ecom/ CPG + freight/ logistics spaces. You care deeply about solving real problems. We're building the Enterprise motion, not just running a playbook.
Parabola had its biggest year ever in 2025. We’re consistently exceeding targets, and there is serious demand that is pulling us upmarket. You’d be working closely with our CRO, COO, CEO and GTM team to shape how Enterprise sales is done here. If you’re an experienced AE (5+ years in SaaS sales) who wants to sell something genuinely powerful with real customer impact, we’d love to talk.

We're using generative AI in a creatively interesting way to build the first AI game that doesn't suck. We're backed by top Silicon Valley investors, and graduated from the first cohort of a16z's SPEEDRUN program, which is kind of like YC for games.
Ideally, you:
* Have worked as a software engineer before, ideally on a small team. * Have built and shipped games before, either professionally or on your own time. * Have experience with full-stack web development, using TypeScript, React, etc. * Love games yourself, and have always wanted to work in the games industry.

Artificial Analysis | https://artificialanalysis.ai | Multiple Roles | San Francisco preferred, remote available (Australia, NZ, LATAM) | Competitive Salary + Equity
Artificial Analysis is an independent AI benchmarking and insights provider. We benchmark AI to help engineers and companies understand AI and make informed decisions regarding which AI technologies to use. We are fast growing with a team of 25+ and have backing from investors including Nat Friedman, Daniel Gross & Andrew Ng. Our benchmarks are cited by NVIDIA, Meta, Amazon, and publications including the Wall Street Journal and TechCrunch.
We are hiring across several roles:

Cleric | https://cleric.ai | Staff SWE, AI | Staff SWE, Product | Founding Marketer | Staff Designer | SWE, Backend | SF Onsite (Designer Remote)
Engineers can't keep up with their production environments: dozens of services, dashboards everywhere, alerts firing constantly. The information to diagnose most issues already exists, but finding it takes longer than fixing the problem. And the more AI-generated code ships, the more services get deployed by people who won't be around to debug them.
Cleric connects to your existing observability stack, autonomously investigates production incidents, and tells engineers what's wrong. We're well funded with years of runway, a small team of AI and infrastructure veterans in SF, growing quickly. Stack: Python, Go, LLMs, Kubernetes.
Some of the problems we work on:
There's no test suite in production. When the AI says "the root cause is X," how do you verify that? You can't A/B test diagnoses. Ground truth labels don't exist. We build evaluation systems that track resolution outcomes over weeks and correlate fixes with diagnoses to build statistical confidence.
When something breaks, everything looks broken. Database latency spikes, five services throw errors, CPU goes up, logs explode. When an agent sees 47 anomalies at once, it needs to figure out which one is the root cause and which are symptoms, across systems with feedback loops, hidden dependencies, and non-obvious temporal relationships.
A single investigation might need six hours of metrics across 50 services, 10GB of logs, 10,000 distributed traces, the last 30 deployments, and the relevant runbooks. LLMs have finite context windows. What's relevant isn't known until you investigate. Getting retrieval wrong means wrong conclusions or exploding costs.
We're hiring:
- Staff Software Engineer, AI: You build the core agent. Reasoning, evals, self-improving feedback loops. You debug agent behavior by tracing reasoning and tool choices to understand why the agent made a specific decision. You build the systems that make a non-deterministic agent reliable, and push it to handle increasingly complex incidents.
- Staff Software Engineer, Product: You define what an AI SRE should actually be. When AI handles the reasoning, how do engineers stay sharp for cases it can't handle? How do you build trust when someone needs to verify agent conclusions at 2AM? You answer these by embedding with customers during real incidents, running experiments, and making the technical calls to ship what works.
- Software Engineer, Backend: You build and scale the investigation platform alongside our senior engineers. Integrations with Datadog, PagerDuty, and dozens of observability tools. Agent reasoning pipelines. Runtime systems that handle real-time data streaming at scale. You'll ship customer-facing functionality across the stack.
- Founding Marketer: Software engineers are allergic to AI hype. Our users already love the product. The challenge is reaching the next thousand teams without setting off their BS detectors. You build the marketing function from scratch: programs, pipeline, infrastructure. You need a technical foundation and the ability to hold a 30-minute conversation with a platform engineering lead without getting lost.
- Staff Designer (Remote): The interfaces for AI agents don't exist yet. How do you make autonomous reasoning legible without overwhelming? You own design across brand, product, and marketing, defining the visual language for a new category.

MixRank (YC S11) | Software Engineers | 100% REMOTE (Global) | Full-Time MixRank processes petabytes of data every month from web crawling. We have hundreds of customers using our data products including Google, Amazon, Facebook, Intel, and Adobe, across industries including Finance, Recruiting, Sales, Marketing, and Security. We’re a fully-remote company with a global footprint in over 20 countries. We're growing, profitable, employee-owned, no dependence on outside funding. Applicants from all geographies and backgrounds are welcome. We are looking for passionate individuals for whom programming is not just a job but it’s something they love to do. We're obsessed with computers, programming, big data, databases, compilers, hardware, math, data science, and the internet. Does this sound like you? Please apply to join our team.
Our code base is very friendly to new contributors. You'll have a fully-functional development environment within hours (fully automated) and be pushing commits on your first day. Deployments to production happen multiple times per day and finish in less than 2 minutes. Effectively all of our codebase is written in Python, Rust, SQL, Javascript/TypeScript, and Nix. The core technologies you'll need familiarity with to be productive are Python, PostgreSQL, Linux, and Git.
We operate at a larger scale than typical startups. We operate two datacenters with high performance servers we've built that are capable of dealing with the volumes of data we process. We've implemented our own distributed file system. We do full-scale web crawls. We download and perform static analysis on the entire universe of Android APKs and iOS IPAs that are published. Unlike a typical startup where you'll spend half of your time in meetings, and the other half fixing bugs from Jira tickets— at MixRank you'll get to challenge yourself with difficult technical problems that will help you to grow as an individual.
We're hiring continuously for the positions below— they aren't singular positions that will close once filled. Our philosophy on hiring is that the candidate is more important than the position. For each new member of the team, we design a custom role and responsibilities that are specialized to their interests. Other companies will come up with a long list of specific requirements for a position with the expectation that you'll exactly replace someone from the team, or that you'll be the perfect tetris piece that satisfies the job requirements decided by a committee. MixRank is more pragmatic: we'll first get excited about having a unique individual on the team, then we'll figure out the best way to accommodate their specific talents.

Evercred (Pre-A stage) | Remote (US) | Technical Co-Founder - AI Agent Infrastructure | $20K/mo + up to 20% equity We're building AI agents that reduce physician credentialing from 90 days to 14 days. $50B market, healthcare orgs desperate for this solution.
THE ROLE: You'd own agent orchestration, monitoring, and ML operations as founding technical leader. We have agents built by external agency launching in 2-4 weeks. You'd evaluate their implementation, build operational infrastructure, and own the technical strategy as we scale from 0 → thousands of verifications monthly.
THE OPPORTUNITY: - 20% equity (founding team level, 4-year vest) - $20K/month cash (adjustable based on equity preference) - Clear path to Series A: $1M ARR by summer 2025 - Own agent infrastructure for industry-disrupting product - Work directly with CEO/CPO, high autonomy
THE REALITY: - 3-4 month runway (aggressive growth targets) - Remote/async-first, US-based for timezone overlap - Paid trial week ($1,400) - mutual evaluation for partnership - Need production ML/agent experience - Must move fast intelligently (AI-assisted development expected)
THE TRIAL: Week 1: Evaluate third-party agent code, build monitoring infrastructure, or pivot to corrective strategy if code needs work. Testing judgment + execution + communication.
LOOKING FOR: - Production experience with LLM agents or ML systems - Can leverage AI tools (Claude/Cursor) to accelerate safely - Comfortable with ambiguity, short runway, high ownership - Wants equity upside, sees potential in healthcare transformation - CTO-level strategic thinking
NOT A FIT IF: - Need structured W2 role with benefits - Want low-risk established company - Optimizing for maximum cash vs. equity potential - Need multiple approval layers for decisions
TO APPLY: Email mark@evercred.com with: 1. Your approach to the trial problem (3-5 sentences) 2. Why 20% equity interests you vs. full cash 3. How you'd use AI tools to accelerate the week
We respond within 24 hours. Strong candidates start immediately.
Healthcare credentialing is broken. Help us fix it.
Translation: Vibe coded solution works great on demo, fails in prod. Freakishly hard problem. Fix it for us real quick, we may or may not pay you. Or just tell us how to do it, yeah that's much easier actually.
Not at all...please don't misinterpret and make poor assumptions. We are building AI agents to work with credential verification using a company that specializes in building AI agents...your interpretations is VERY far off the mark. Our founder is an emergency medicine MD who has raised directly from physicians and we've got real early traction. I do hope we can get some actual thoughtful applicants, thanks for the earlier reply self-selecting out :)

EDIT: Looks like my comment was detached from its thread (https://news.ycombinator.com/item?id=46857847) without a comment explaining why. It's not breaking any of the stated rules at the top, and it seems like it would be common sense to let someone know they should expect a message (especially considering how temperamental email filtering can be these days). If this _is_ against the rules, I'd appreciate it if future hiring threads stated as such so that people like myself that have been trying to find a job for 7+ months can stop wasting our time here. I understand how it can be challenging to moderate a forum like HN, but the moderation priorities seem pretty disappointing, unfortunately.
