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.

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 antibody 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 two core roles:

1. 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.

2. Bioinformatics Developer (Antibody Discovery): You will work on the scientific core, developing blocks for NGS data analysis and antibody structure prediction. You should be fluent in both code and biology.

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.

Gobii AI | Senior Software Engineer | REMOTE (US) | gobii.ai

Gobii is the easiest way to deploy browser-use agents in the cloud or on-premises. We're building an open-core AI workforce platform—browser-native agents and automation tools. We have paying customers.

The entire team contributes to browser-use. We also have contributors to Apache NiFi, LiteLLM, and RA.Aid (open-source coding agent I created). Open source is core to how we build and how we think. We're backed by Open Core Ventures.

HQ is San Francisco, but much of the team is in the DC area. East Coast timezone preferred, DC area even better—but we're fully remote.

What we're building: The orchestration layer for browser-use and AI agents. Systems that navigate, reason, and execute on the real web.

Who we're looking for: You've built agentic systems that shipped to production. You have opinions about tool use, context management, and why most "agents" are just glorified prompt chains. You strongly prefer working in the open—a significant part of this role is contributing to OSS repos. We strongly prefer candidates with existing open source contributions.

Why now: We have strong traction and are expanding the team. You'd be early—with real influence over product, architecture, and how we work. High autonomy, high trust, small team of people who know what they're doing.

Comp: Cash + healthcare + modest 401k match + options. In line with SF-based VC-backed startups at pre-seed stage.

Stack: TypeScript, Python, browser automation, LLM orchestration.

Email: careers@gobii.ai (subject: "HN")

You'll work with billion-dollar enterprises solving their hardest, most mission-critical automation problems.

If you're excited about working at the nexus of data, automation and AI, and want to make a significant impact in an early, well-capitalized startup with large enterprise design partners, we'd love to hear from you.

Roles: Product/Design Engineer.

SpruceID (YC W21) | REMOTE (US-Based Preferred) | Full-Time | spruceid.com

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.
