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.

I love how you provided the tax breakdown and pretty impressive for Spain (which is notoriously a tax hell)!

Thanks! It’s a common surprise. The Basque Country (Bizkaia) has fiscal autonomy, so the rules here are pretty different from Madrid or Barcelona. It allows us to flip the 'high tax' narrative and offer a massive net upside for expats.

Does the Beckham Law apply as well?

Technically, no—and that’s actually a huge plus.

The 'Beckham Law' (24% flat rate) applies to the rest of Spain. Bizkaia has fiscal autonomy and a different system to attract talent: you get a 30% exemption on gross income plus you can deduct specific expenses (like your apartment rent, school fees, etc.) from the taxable base.

The total tax exemption can reach up to 50% of your gross income.

This stacking effect (exemption + expense deductions) is why the effective rate here often drops well below the national 24%. For example, on a €100k salary, your effective tax rate typically lands between 15-20% (depending on your rent and family status).

Hatchet | Founding Engineer | NYC or REMOTE (US and EU) | https://hatchet.run

Hey HN! I'm Alexander, one of the founders of Hatchet. Hatchet is an open-source platform for running background jobs at scale.

We're hiring engineers who are excited to build the next class of engineering primitives, starting with queues, background tasks and durable execution. We started in early 2024 after launching our distributed task queue (https://news.ycombinator.com/item?id=39643136).

Hatchet is currently used by thousands of engineers for all kinds of workloads: log ingestion pipelines, code review agents, video encoding, GPU scheduling, etc. Our target customer is fast-growing startups who have a strong need for background jobs system. These days, that tends to be AI companies, though we're general-purpose and not exclusively targeted for AI workloads.

Stack: Postgres, Go, Typescript, React, Kubernetes

Apply here: https://www.ycombinator.com/companies/hatchet-run/jobs/SNpCm...

Or email me at alexander [at] hatchet [dot] run

Your website is INCREDIBLY slow, and I have a very good laptop with dedicated GPU. Somehow some JS is killing the whole thing.

Anyways, the concept looks cool, but I'm failing to see a real value add to something like Temporal. What is it?

Oh no, haven't gotten reports about the website being slow, thanks for flagging! Which browser are you using?

Regarding Temporal, our goal is to create the best developer experience possible, and we started Hatchet because we felt that Temporal misses the mark (I used Temporal for years before starting Hatchet).

The primary difference is that we're not solely focused on durable workflows, we're a general-purpose background jobs platform which offers durable workflows as a feature. In our view there are a set of equally important primitives: tasks, events, streaming/pubsub, concurrency, priority, rate limiting, scheduling, and yes, durable workflows.

Tasks being the entrypoint to the platform, rather than immediately dealing with the overhead of durable workflows, generally makes Hatchet easier to adopt for engineering teams. I wrote a little more about how task queues relate to durable execution here: https://hatchet.run/blog/durable-execution

We've also invested quite heavily in platform features like logging, observability, alerting, and our UI which either aren't offered or are underdeveloped in Temporal.

But ultimately I'd encourage people to give both a try - we're both MIT licensed and can easily be run locally.

I’m on chrome. Maybe it was a hiccup on my end.

Looks interesting.

We are in the process of looking for some alternatives to temporal/prefect. Would you mind sharing your email so I can send a few questions along with my cofounder?

Yep! Feel free to email me at alexander [at] hatchet [dot] run

The website seems fine to me. I'm using Chrome on Linux with an X1 Carbon (so integrated graphics, no fancy GPU).

I didn't notice the website being slow (Firefox on android, midrange device)

Blueberry Pediatrics | Full-stack Senior or Staff Engineer | REMOTE (US only)

American healthcare is seldom affordable, accessible, or high-quality. We are fixing this for pediatrics. Blueberry is the most affordable option amongst our competitors. We practice the highest quality pediatric telemedicine, as evidenced by our exclusive hiring of board-certified pediatricians and the usage of at-home medical kits. And, we’re accessible 24 hours a day.

Our success is shown in the lives we save, the costs we save our insurers, and our exploding B2B and D2C business.

As you can imagine, pulling off affordable high-quality healthcare is a challenge. It requires a lot of engineering ingenuity, a C-suite aligned with positive patient outcomes above short-term profits, and a great product team.

We use Django, Hotwire Turbo (an HTMX-like framework), Pytorch, Sklearn, and Flutter. Experience in these technologies helps, but what’s more important is general full-stack knowledge, curiosity, and a strong work ethic.

Full-stack engineer: https://jobs.ashbyhq.com/blueberrypediatrics/dc8108f3-34ed-4...

Our homepage: https://blueberrypediatrics.com/

Our engineering blog: https://engineering.blueberrypediatrics.blog/

Interesting.

Question, while imaging is a bit less common in pediatrics. How are you handling medical images and bloodwork?

It seems like being a pediatric service, there's an opportunity to take ownership of these medical documents, both for life-long storage and centralization. Also if tech is a brand differential it seems like it would be a simple place to get a competitive advantage.

At Sage Bionetworks, we believe in the power of open science and interdisciplinary collaboration to create a new vision of human health. We strive for actionable biomedical insights through the responsible sharing and reuse of data, all guided by our deep scientific expertise and diligent governance controls.

We are hiring a Backend Software Engineer to join our technology team at Sage Bionetworks.

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:

  * Merge Queue: Ensure your PRs keep the builds you care about green at any scale.

Cleric | Staff SWE, AI | Staff SWE, Product | Head of Marketing | SF Onsite | $160K-$240K + Equity

Engineers can't keep up with their production environments: dozens of services, dashboards everywhere, alerts firing. The information to diagnose most issues exists, but finding it takes longer than fixing the problem. AI generated code is making this worse.

Cleric is an AI SRE that autonomously investigates production issues and surfaces findings to engineers. It connects to your existing tools, reasons through the evidence, and tells you what's wrong. We believe engineers should ultimately be accountable in production, and our goal is to help them go much faster.

The hard part is making agents reliable when there's no single right answer. We've built evals, memory systems, and feedback loops that improve with every incident. Gartner just named us a Cool Vendor, we are well funded with years of runway, and most importantly the engineers that use our product find it very sticky.

We're hiring the following roles:

- Staff SWE, AI: Build the reasoning engine. Design evals, debug agent behavior (not just code), expand what it can handle. You've built agents and operated distributed systems at scale.

- Staff SWE, Product: Define what AI SRE should be. Spend time with engineers during incidents, find gaps, decide what to build. You've owned products and know production pain.

- Head of Marketing: Engineers love the product but we need to reach more of them. Software engineers are allergic to AI hype, and you'll need to cut through it. Technical background required.

Shorebird | Mid-Senior C++/Runtime OR Dart/Cloud Engineers | REMOTE (North America) | Full-time | $150-230k + equity + benefits | https://shorebird.dev

Flutter/Shorebird founder here. Flutter is used by millions of devs (and nearly ⅓ of free apps submitted to AppStore), but is missing services for businesses. We offer Flutter-related SAAS used by 1000s businesses globally, on track to profitability early 2026.

As part of our over-the-air updates “code push” product, we’ve built a custom compiler and runtime for the Dart language, primarily written by me (founder/CEO). We need a fulltime engineer to take over primary responsibility for all of our C++ code (Dart & Flutter forks, custom runtime, compiler, etc.) and evolve it further than I could alone. You don’t need to be a compiler/runtime expert. You do need to be capable of working on large open source projects, be comfortable with C++, want to work at a startup, work well independently (we’re remote) and want to learn and work on lots of different areas of code. If you’ve contributed at least a little to WebKit, Godot, Firefox, or any other open source project and are at least compiler/runtime curious, you will likely find this role extremely rewarding.

For our second role: we serve 10s of millions of devices daily from our cloud, (2k+ RPS sustained), built mostly in Dart on Google Cloud + CloudFlare.

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.
