Pareto.AI is in the premium data annotation space, focused on ethical, high-quality data annotation. We work with almost all of the frontier labs. We are a fully distributed, remote-first company with engineering teams spread around the world. Some of us work hybrid from our office in SF.

At Pelairo we're building the most intuitive and flexible Laboratory Information Management System (LIMS) on the market. "Manage the lab, not the LIMS!"
We're looking for a hands-on Principal Engineer to lead the design and delivery of our backend—built on TypeScript + NestJS—and help our small team iterate quickly with confidence. You'll turn ambiguity into shippable slices, help set technical direction, and raise the bar on reliability, security, and speed.
What you'll do:
- Own the backend: spend meaningful time writing and reviewing production code. - Architecture stewardship: keep the system coherent as we scale questionnaire-driven workflows and FHIR pipelines. - Reliability & quality: Establish testing strategy (unit/integration/contract/E2E), migrations, rollouts (feature flags). - Observability: Instrument tracing/metrics/logging, build dashboards/alerts; drive incident reviews. - Raise the engineering bar: define and enforce code review policy, branching model, testing strategy, and CI/CD gates. - Partner with Product & domain experts: translate healthcare workflows into configurable front-end modules; ensure back-end transforms to valid FHIR in Medplum. What makes you a great fit: - 8+ years building production systems, including principal/staff scope in a startup or similar pace. - Deep TypeScript + Node.js and expert-level NestJS in production. - Track record leading cross-team projects and influencing architecture without heavy process. - Product sense and crisp communication; comfortable owning ambiguous problems and shipping quickly with guardrails. - Bonuses: FHIR/Medplum, healthcare data workflows, HIPAA/SOC 2 experience, comfortable jumping into modern frontend (React/Next.js) when needed.Stack: TypeScript (Next.js and NestJS), Medplum, AWS (Cognito, Fargate)
Visa/relocation: No
How to apply: Email hiring [@] pelairo.com and mention "HN Who's Hiring November 2025". (We know the website needs some work, but the product is our priority right now.)
We're looking for someone with deep healthcare integration experience to hit the ground running. Ideally they're a pragmatic backend expert to help us scale as we continue to grow.

Ascento develops autonomous security robots that patrol outdoor areas to detect and report. All in support of security guards. We stay away from conflict, just robots driving circles around buildings in remote boring places. The technical challenges however, are far from boring.
We are looking for a full stack engineer to join as a core member of the off-robot software team. This is the software that plans, configures, operates and creates insights from data collected from the robots. You would work across the whole cloud-stack, consisting of Frontend (React), Backend (Typescript / Go), Infra (Terraform / AWS / GCP).
The cloud software team is still small, meaning you get a chance to help set priorities, guide long-term architectural direction and figure out how to best help our users. We celebrate pragmatism, we work hard to make simple systems and we help each other to hyperfocus.
Sounds like the place for you? Drop an email to sijmen@ascento.ai. I'm curious to read what about this ad caught your interest.

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.
Today, we are hiring highly capable 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 everyone on our team has a high regard for those in the public service. We have a strong engineering culture. We are not a SaaS product or AI wrapper, and 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 incredibly ambitious. 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.
The potential impact of this work cannot be understated, and this is not the right job for you if you want to "join a cool new AI startup" and make a fast exit. However, if you care about our mission, then you will have the opportunity to make meaningful outcomes for society that will make you feel proud.

We are building a new programming language (BAML) to build AI agents -- the "typescript" for LLMs. We are open source: https://github.com/BoundaryML/baml
A big part of this language is all the tooling around visualizing non-deterministic code, visualizing code, and getting great observability (e.g. our language has type information at runtime unlike TS).
We are looking for engineers with experience with Rust, programming languages, and/or compilers. Any amount of experience is fine.

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 a small UK-based free-to-play gaming company with a distributed EU team, growing fast after recent success and scaling our backend platform. We’re looking for two roles, from mid-senior to senior engineer with at least 5+ years of experience.
Backend: Strong in backend development, ideally Java, but open to those willing to learn. DevOps experience is a plus, or a strong desire to build it.You’ll be expected to do devops as part of this role.
Fullstack: FE and APIs, you’ll also be asked to write SQL and some Java Controllers that access data. It’s ok if you don’t know Java, but our controllers are written in Java and you’ll need willingness to learn.
Our stack includes Java, Python, TypeScript, Angular, SQL, AWS, Kubernetes, Postgres, Trino, Flux, Flagger, and Terraform.
Our engineers must be able to think product-first, and take a task from idea to production, work across the full cycle. You must write your own code, AI assistance is fine, but you must be able to produce all your work independently.
We are looking for candidates that can write SQL, our approach when it comes to the DB is SQL first. We also value clear thinking and communication, you should be comfortable sketching simple architecture or flow diagrams (boxes and lines, nothing formal) to explain your ideas.
To apply, please send an email to jack[at]splash.tech with the subject “Backend Hackernews 2025” or “Fullstack Hackernews 2025”.
Please send any git/bitbucket/source-forge project that represents your coding otherwise I’ll ask you to complete a small test project.
