At Tandem Health we're building a clinician copilot to allow clinicians to focus on care rather than administration. We’re building, launching and iterating quickly, and already have >1000 organizations using our product.
Our core product listens in to the patient-clinician encounter to generate medical records, allowing clinicians to save 5-10 minutes per patient. No longer do clinicians have to catch up on administration after hours. Some even tell us that their partners notice they're much more relaxed after starting to use our product, and we couldn't be happier :)

● Driven to constantly learn and are always searching for the bigger picture
● Strong in clear thinking and written communication
● Have experience with many languages but can be effective in any language
● Appreciate that all mature software solutions accumulate technical debt and understand how to continually reduce debt and complexity

We're hiring across disciplines for engineers who work with Unix and have fluent written and spoken English:
● Backend Servers: Strong in C, Concurrency and Distributed Computing
● Backend Servers: Strong in Java
● Infrastructure: Strong in building infrastructure tooling to program infrastructure.
● Frontend: Strong in Javascript, Typescript, React, and advanced UI and browser applications
● Artificial Intelligence: Strong in Neural Networks, AI Workflows, AI Models.
● Product Design: Ability to spec and build out clean UIs and dashboards.
We value people who are generalists and are interested in learning, developing, and applying expertise across multiple areas.

We are private, which gives us the freedom to explore many areas without investors and profits being the sole objective.
Full-time only. Remote only. We start out on a full-time trial contract basis for up to 3 months and use this period as an extended work interview for both sides to assess fit for long-term employment.
Please email hn.remote.jobs@vdx.tv if this sounds like the right fit for you.
We are a new discretionary, tech industry focused L/S hedge fund, founded by a portfolio manager with 15+ years of experience at a well known Tiger Cub. I lead the data/technology team here and previously spent ~6 years in a similar role at that firm as well. We are not the only ones trying to figure out how to use AI in investing but in a world where there are lots of people trying to build picks & shovels, this is an opportunity to be one of the goldminers at a greenfield, new firm. This role makes sense for people who are interested in finance/investing (although you do not necessarily have to have experience in the industry).
We are hiring for a frontend IC engineer for our internal web application.
One of our core advantages is marrying domain experts (ie. experienced fundamental investors from top tier hedge funds) with tech talent. Our frontend (the design, the UX, the UI) _really_ matters to tie the two sides together. The quality of the data we can collect, the speed of testing new ideas, and there ultimately success is driven by the quality of our frontend -- as unintuitive as that might sound.
Our tech stack: * Frontend: Typescript, Vue3 * Backend: AWS, Cloudflare, Supabase/Postgresql, Typescript *
- We work very hard, hours are long, and people are very dedicated to the mission. It is not for everyone, but for those interested in competing in financial markets, love startup atmosphere without near-term existential risk, and want to work with super smart colleagues (both technical and investors!), this could be a great fit.
- We're in full-time in office in NYC, so that's a requirement for FTE. We are potentially open to exceptional contractors located remotely.
- Target salary 180-250K, depending on experience + Bonus/Carry (hedge fund equity equivalent)
If you are interested, I would love to hear from you:
- Contact: ai at nx1 dotcom , I'm Alex. - Please include resume or LinkedIn and some example of something you have built (could be Github, could be your current company, anything really)

We're looking for a Tech Lead and Senior Engineering Manager based in Los Angeles or Mexico City (hybrid). You’ll work closely with the founders, lead a small team of senior engineers, and take ownership of key technical decisions. It’s a hands-on role with room to influence both product direction and team structure as we grow.
We’re also hiring senior backend, frontend, and AI engineers across LATAM (remote). You’ll be part of a tight, experienced team focused on building tools that solve real operational problems inside legal teams.
Our stack includes Python, JavaScript/TypeScript, Postgres, Kubernetes, and GCP.

Looking for something more meaningful? How about the opportunity to have a direct impact on the property maintenance experience for hundreds of thousands of residents?
Welcome to the future of property maintenance. Property Meld’s vision is to radically improve how the property management industry handles property maintenance. If you’ve ever had a maintenance issue at your housing rental, you know how much of a pain it can be to get it fixed quickly and reliably. It doesn't have to be this way. We're rethinking the entire property maintenance experience from the ground up with two things in mind - first, driving the cost of doing maintenance to the absolute minimum, and second, providing an experience to residents and property owners that makes them want to stay with their property manager. If you are excited about turning something that has historically been a negative experience (maintenance) into a positive experience, we'd love to talk with you.

Saildrone is the world's leading collector of ocean related in situ data via uncrewed vehicle, above and below the sea surface. We work with governments, civic agencies, foundations, universities, and private companies around the globe to derive better information about our oceans and seas - be it sailing drones into the eye of hurricanes to obtain new scientific storm data, mapping out the ocean floor, collecting new CO2 data in hard-to-reach areas, counting biomass to establish fishing quotas, or detecting and stopping illegal fishing and drug trafficking.
Maybe you saw that we've repeatedly hucked drones into category 4 hurricanes[1]. Or maybe that we recently completed a transoceanic cable survey for Meta[2]. And maybe you saw that we just wrapped up a big demonstration for our partners in NATO[3]. Or maybe you didn't see any of that, but you're still intrigued by the idea of autonomous, long endurance sailboats that help us better understand our planet.
Whatever the case, we're hiring for a breadth of different positions across our organization. In software, we're hiring for folks in our Perception, Platform, Frontend, and Vehicle teams. Stacks vary from team to team, but we're looking primarily for folks with backgrounds in C++, Python, and/or JavaScript (Node, TypeScript, React). All software positions are hybrid roles based out of Alameda, just a quick ferry ride across the Bay from San Francisco.
In addition to software engineers, we're also hiring for a bunch of other positions across the company in production/manufacturing, technical operations, and more.

We're a software engineering consultancy that builds enterprise software the right way. We negotiate the right to open source all our client code, maintain a handful of popular libraries, and our engineers contribute to Django core. We sponsor PyCon, DjangoCon, and Django Girls because we're invested in the ecosystem we build on.
We're looking for software engineers who value software design, system architecture, and collaboration. You should be comfortable with about half of these areas and eager to learn the rest: web application security, relational database design (PostgreSQL, beyond "SELECT *..."), Django internals, React, and distributed systems. What you'll actually work on: complex state machines for financial workflows, multi-tenant architectures with row-level security, custom database functions when the ORM isn't enough, and React frontends that handle real-time data without being a mess of useEffect hooks.
We're a small team where you'll own features end-to-end (database design to React components) and have opportunities to shape technical decisions. You'll get paid to write source code with a team that practices empathy and values work-life balance. If you've ever wished your job involved more elegant state machines and fewer marketing landing pages, let's talk: info@fusionbox.com.
