Ask HN: Who is hiring? (January 2026)

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.

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.

Ezra | Senior+ Engineer (Full-Stack) | REMOTE (LATAM / US Eastern) | Full-time

****************************************************************

Ezra is a venture-backed startup building at the intersection of sustainable finance and artificial intelligence. We're building a platform to accelerate capital deployment into climate solutions and other world-positive investments.

I’m Rob, the CTO, and we’re looking for multiple seasoned, full-stack Senior+ Engineers (6-10+ years exp) to significantly contribute to the development and scaling of our core platform.

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.

Apply: https://jobs.ashbyhq.com/cleric Or email me: willem-hn@cleric.ai

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.

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.

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.

Sleep is vital to recharging mentally, restoring our bodies physically, and fighting off disease. Sleep is so core to our health that it's the activity we all spend most of our life doing.

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.

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.

CareIgnition | Senior 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.

If interested, reach to me at vikram.chauhan [at] careignition.com

WireScreen is a fast-growing Sequoia-backed Series A startup building the go-to open source intelligence platform for navigating global supply chains and China-related risk. While China maintains some of the world’s most detailed corporate ownership records, the real challenge is connecting the dots. That’s where we come in—surfacing the networks, relationships, and financial ties behind companies to support national security, compliance, and regulatory oversight.

We’re looking for senior software engineers to build our data platform and help us ingest and model messy, unstructured data into insights and actionable intelligence. At the heart of this is a 50m+ entity knowledge-graph with 200m+ relationships represented - and we need your help to build a system that can scale this up by an order of a magnitude. Today, we mostly use Python, Postgres, Airflow and Pyspark.

If you have prior startup experience, can bring strong Python (PySpark is a big plus) experience and have previously worked with TB-scale data sets - we’d love to talk to you.

Apply here: https://jobs.ashbyhq.com/wirescreen/e9d8e7e3-c737-43ee-8c7e-...

Or you can reach out to me directly at leo.green@wirescreen.ai - I lead recruiting here at WireScreen, but if I don't know the answer I'll ping our engineering folks and come back to you fast.

Pango | Founding Full-stack Software Engineer | On-site (hybrid) in Stockholm, Sweden (Visa Sponsorship possible) | Full time

* You are happy to take on work that in a large company is divided into a dozen roles, and execute it all at a good enough level.

* You have strong proficiency in any backend language or platform, with a strong willingness to dive deep into PHP/Laravel OR strong proficiency in JS/React.

* E-commerce (Shopify, Magento, other platforms, shipping carrier integrations) experience is a plus.

You will take a key role in shaping the product and company, with ability to make an impact and advance career limited only by your aptitude and interest.

ProPublica | Director of Product Engineering | Remote (US only) or NYC | Full-time

ProPublica is a non-profit newsroom that investigates abuses of trust in the public interest. Journalism we published last year shed light on the impact of DOGE and ICE, investigated right-wing militias, told stories about the US medical system, and more. Here were our most-read stories in 2025: https://www.propublica.org/article/propublica-most-read-stor...

I'm the Senior Director of Technology. I'm hiring a pragmatic, mission-driven Director of Product Engineering, who will report to me, in order to provide more support for our product engineers who work on our publishing and data products. (This is not a reporting position.) You'll directly lead and manage a small team of engineers and help us to create and maintain great engineering processes.

More about the role here, including a direct route to apply:

The expected salary range for this position is $170,000 to $180,000. We cannot sponsor visas and must hire in the US. The role is almost fully remote: we have two in-person week-long summits a year.

Stealth | Software/AI Engineer | Remote Anywhere | Full Time

Hello, I am bootstrapping an AI companion startup. I believe that within 10 years, more people will date AI than humans. I think this is neither good nor bad, just interesting, and I want to build something in this space.

I am looking to hire someone with strong technical and problem solving skills. You will be seeing a lot of problems for the first time and need to just figure out how to hack a solution. Sometimes that involves writing code but not always. It is ok if you don't have prior AI experience.

Interesting problems we will work on:

- extreme latency issues while providing a fully multimodal experience (audio, video, text)

- building models that predict when to interrupt in a conversation

- building models and control systems for emotion

- generating avatar response in real time

- custom 3d models from input image

- real time or very fast video generation with custom characters

- llm memory

As I am bootstrapping this, I can only offer up to $4,000/mo ($50,000/yr) at the moment. If you are interested, please email James at gcyiuqy1 [at] gmail.com

Positron | Bootstrapping Startup | South Korea | Co-founder

Equity-only co-founders. If you must take a salary position, send us a resume with "Salary only" and we'll check back later.

We're developing an efficient social-decision model so that communities can organize social-finance campaigns and effectively administrate funds without being beholden to one creator. Keeping funds in the hands of backers creates accountability and is one key to taking social finance to the next level.

We say that our social tech "makes the money smarter." It will do this by making communities smarter. How we do social will change how every future social platform gets built and will upset every social product on the market. Society will benefit tremendously from the more coherent discourse.

To bootstrap our platform, we are developing an music visualizer called MuTate. It will soon be powered by our in-house machine learning tricks, which do not rely on back-propagation in order to enable radical forward architectures that are smaller and easier to develop and train. This work directly impacts our mission and aligns us both with consumer enthusiasm for small & local AI to run outside the cloud and with people working on hard problems that need AI tool-kits they can embed their own world models within.

We are using PrizeForge as a better kind of Patreon while we finish our crowd cognition implementation and start to integrate social decisions with our existing social finance.

Our entire tech stack is Rust where possible. We use Leptos, Axum, Postgres with SQLx. It's like a full-stack typescript setup, but with Rust and WASM. MuTate uses Rust, the Vulkan API, and Slang.

Anyone who materially accelerates the trajectory of the company will participate proportionately in the rewards. Our work on MuTate will put us default-viable. Our work on crowd cognition and community-organized campaigns will likewise make use default-viable.

Prototype two-dimensional fund raising: https://prizeforge.com Career listings with more details: https://positron.solutions/careers MuTate Github repo: github.com/positron-solutions/mutate

Korean language skill is optional but anticipate learning business Korean and translating a lot. Same timezone is as far as will be considered remote unless you're physically stuck in Ukraine etc and begin by contributing on MuTate.

RunReveal (https://runreveal.com) | Systems Software Engineer | Austin, SF (US Work Auth required) | Full-time

RunReveal is the Security Data Platform that's building tools to help companies detect and respond to threats in their network. We're a team that values speed, quality and curiosity. Our stack is Go, NextJS (TS), Postgres and ClickHouse. We believe that companies should be able to own their security data and get value out of it too and so we've built a platform that can be deployed anywhere. SIEM sucks, so we're here to fix it.

If you're into self hosting or running a homelab, or you're using LLMs to enhance your development workflow and extend your knowledge and not just regurgitate slop, or you're always looking for opportunities for self improvement, you're in good company at RunReveal.

We've got phenomenal customers like Cursor, Harvey, Temporal, Linear, DigitalOcean, ClickHouse and AngelList among many others that we work with on a daily basis to improve the product.

We're especially interested in folks that have experience working with petabyte scale databases. We use ClickHouse, but experience with other similar large scale data technologies like Iceberg, Flink, Spark, ScyllaDB, Cassandra, InfluxDB, TimescaleDB, BadgerDB etc would also be valuable.

Reach out to me via alan at the company domain and mention hn who's hiring January '26 in the subject line.

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.
