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.

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 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)

Chestnut builds software insurance carriers actually run their business on. We replace legacy, manual distribution systems with real-time data, automated workflows, and AI-driven tooling in a space that hasn’t changed much in decades.
This is product engineering. We ship to real customers, operate what we build, and spend time fixing the sharp edges that show up in production.
You’d work on backend-heavy product features around onboarding, compliance, payouts, and integrations. A representative problem: building a commission payout flow that ingests messy carrier data, applies complex rules and hierarchies, explains results to ops, and executes payouts that must reconcile cleanly with finance—while handling holds, chargebacks, retries, and partial failures.
Stack: Go, TypeScript/React, Postgres, Temporal, Kubernetes, AWS, LLM tooling.
Roles:
- Senior Software Engineer – Product / Backend (https://jobs.ashbyhq.com/Chestnut/fbbb7601-3d31-48b4-8639-75...)
- Staff Software Engineer – Architecture & Scale (https://jobs.ashbyhq.com/Chestnut/f28c5ee5-12aa-4e7b-b0ea-f5...)

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.

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're a VC-funded startup (recently raised $51M Series C) building an infrastructure orchestrator and collaborative management platform for Infrastructure-as-Code – from OpenTofu, Terraform, Terragrunt, CloudFormation, Pulumi, Kubernetes, to Ansible.
On the backend we're using 100% Go with AWS primitives. We're looking for backend developers who like doing DevOps'y stuff sometimes (because in a way it's the spirit of our company), or have experience with the cloud native ecosystem. Ideally you'd have experience working with an IaC tool, i.e. Terraform, Pulumi, Ansible, CloudFormation, Kubernetes, or SaltStack.
Overall we have a deeply technical product, trying to build something customers love to use, and have a lot of happy and satisfied customers. We promise interesting work, the ability to open source parts of the project which don't give us a business advantage, as well as healthy working hours.
If that sounds like fun to you, please apply at https://careers.spacelift.io/jobs/3006934-software-engineer-...
You can find out more about the product we're building at https://spacelift.io and also see our engineering blog for a few technical blog posts of ours: https://spacelift.io/blog/engineering

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.
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).
