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.

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
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.

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. Yet sleep disorders are some of the most underdiagnosed health conditions on the planet, with an estimated 80% of obstructive sleep apnea patients undiagnosed and untreated
EnsoData uses machine learning, integration with pulse oximeter hardware, mobile apps, and clinician review UIs to automate sleep study scoring and give sleep clinicians tools to find and help patients with sleep disorders.
We're hiring a product manager to uncover what features our customers crave most, conduct discovery research in the sleep industry, define and prioritize product requirements, partner with engineers to ship features, and work with marketers to tell compelling product stories. You'll manage the product development process from whiteboard mockups tested with real users through to detailed specs and launch, breaking down ambiguous problems into releasable slices that bring AI-powered sleep diagnosis to more patients.

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. We are specifically looking for teammates in Central and South America (LATAM) who can work US Eastern hours. This is a high-autonomy role for a proven generalist who is deeply product-focused and takes complete ownership of features from concept to production.
The Role:
Drive technical delivery of full-stack features end-to-end, collaborating with Product and Design to define requirements and ensure engineering quality.
Design and develop scalable components and APIs across our backend and frontend.
Work to integrate, serve, and iterate on model-powered features and RAG systems.

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.

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")

We're looking to expand our team with creative minds who want to solve real-world problems and impact a massive industry. We are an open-minded, collaborative, and international team.
Currently, we're hiring for two key senior roles:
---
Senior Full Stack Developer (TypeScript)
Location: Remote (EU) / Berlin
Stack: TypeScript, React, Node.js, Cypress, Kubernetes, AWS
Mission: Take full ownership of features, shaping both the frontend and backend of our product. You'll have the responsibility to extend and build upon our platform to make it more valuable, reliable, and maintainable. We value a trunk-based development workflow with daily releases, comprehensive end-to-end testing, and a solid CI/CD pipeline.
You have: 5+ years of hands-on engineering experience, substantial expertise in JavaScript/TypeScript, and experience with Node.js (React is a plus).

KoBold Metals is a scientific mineral exploration and development company focused on critical minerals
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.

Ideally you've already graduated, but if you still have one or more years left of school, please feel free to apply anyway, and if you're the right fit for the team we'll figure out a way to accommodate your schedule. https://www.ycombinator.com/companies/mixrank/jobs/Fnwsojk-j... --

Kyber is an open-source SDK and platform to control remote machines, from Remote Desktop to Robots Teleoperation/Teleobservation.
Kyber is a multi-stream and multi-actuator transport in extremely-low latency, over Quic; it encloses the server, the client and the protocol.
One could use Kyber to control robots, drones, desktop, servers in the cloud or just remote rendering of interactive 3D programs. Kyber is done for Remote RealTime, where every millisecond matters.
Kyber is developed by engineers from the VLC and FFmpeg community, and we code in Rust, in C and in assembly. We have some development in Go too.
We're a quite technical team, but cool to work with.

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-...

Trunk is an a16z funded (25M) Series A dev tools startup, redefining software development at scale. At Trunk, our mission is to help teams create high-quality software quickly. We've helped engineerings teams at: Google X, Zillow, and Brex to understand why their builds fail, which tests are flaky, and how to ship code faster without sacrificing reliability. AI has made writing code 10x faster, but shipping is still painfully slow. The bottleneck has shifted downstream - to merge conflicts, flaky tests, inconsistent code quality, and dozens of other frictions that drain productivity and morale. 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. *Flaky Tests: Detect and eliminate Flaky Tests. Our tech stack: Frontend: Typescript, React, Next.js, AWS Backend: Typescript, Node, AWS Data pipelines: Dagster, Python, polars CI/CD: GitHub ActionsUnlimited PTO (and we all actually take PTO), competitive salary and equity packages! Please apply here: https://trunk.io/jobs
We’re on a mission to give humans and LLMs reliable and fast access to web data.
Web scraping used to be the same for decades (brittle scripts that break constantly). We're automating that end-to-end with LLMs that build and maintain data pipelines. We're also heavily focused on making ethical scraping the default (robots.txt checks, rate limiting, etc.).
All 3 founders have spent years in the trenches writing web scraping and ETL software and still do it almost every single day. We’re making sure every team member can do the best work of their career at Kadoa.
We are looking for people who share our passion for software craftsmanship, data, and AI.
We are growing fast, have a no-bullshit culture, and try to minimize the distance between the code you write and the customers who use it.
We have openings for:
- Senior Frontend Engineer: https://www.kadoa.com/careers/frontend-engineer
- Senior Software Engineer: https://www.kadoa.com/careers/senior-software-engineer
If that sounds like you, please email me at (adrian at kadoa dot com) and mention HN in the subject line. AI slop applications will be filtered out immediately ;)
