I'm the cofounder of Krea (https://www.krea.ai), a startup in San Francisco building browser-based AI creative tools to improve the workflows of artists, designers, and creatives. Small team (~15); millions of active users; and we've raised over $83M from top silicon valley firms.
We're looking for talented engineers who want to tackle hard technical challenges with smart people while building a creative platform that big companies and startups will rely on.
The job:
- Build distributed systems to process massive (billions of files, petabytes), amounts of image, video, and 3D data, solving scaling bottlenecks as you go.
- Work with our research team to build ML pipelines and deploy models to make sense of raw data (example - find clean scenes within videos).
- Learn ML engineering from world-class researchers on a small tight-knit team. As you’re building data pipelines, you’ll contribute to foundation image, video, and world models from 0 → production, and see them used by millions of Krea users.
- Play with massive amounts of compute on huge Kubernetes GPU clusters; our main GPU cluster takes up an entire datacenter from our provider.
Our tech stack: python, pytorch, k8s, a rotating cast of data tools (e.g. DuckDB, massive relational dbs, PyArrow, etc.)
You should apply if you are an excellent generalist engineer with strong backend experience and an intuition for systems design. Bonus points for deep experience with distributed systems, kubernetes, and existing ML or data experience (though not required!). Cool side projects are a green flag.

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.
You can see a list of open positions on our career page: https://www.saildrone.com/careers

It’s a shame that we have unbelievably good hardware like collaborative robots (cobots) that could transform warehouses and yet they still struggle with basic tasks like unloading mixed pallets. Why? Because today's software can't handle real-world chaos.
That's where we come in. At ko-br, we're building the AI brains that make robots truly adaptable. Our physical AI models tackle messy, unstructured problems starting with depalletizing of mixed boxes in dynamic warehouses. Think real-time adaptation to shifting pallets, mixed SKUs, and unexpected failures.
We're a deep tech startup at the crossroads of AI, robotics, and human-machine interaction. While warehouses are our first battlefield, our core mission is physical AI. So you need to be comfortable with the idea of pivoting to other sectors like education (ex: building robots for schools and universities).

I'm Jonas, lead architect at Nexus Intelligence. We’re a software startup backed by a16z that’s building industrial automation systems for companies at the forefront of the US manufacturing renaissance. Our initial product is an agent-based platform for developing & operating legacy control systems, a set of platforms critical to automotive, food, energy, and other industrial sectors. Our vision is to bring AI-enabled workflows, development tools, languages, and runtimes into the manufacturing ecosystem - ultimately becoming the platform on which all modern industrial automation processes are built and deployed.
The team currently consists of Chris (CEO and founder, previously at Tesla, Stanford CS & MBA) and myself (automated biotech labs at Zymergen and Counsyl, dev tools at AWS, Cornell PhD). The first version of our product is in use by customers. You'd join us for the exciting and fast-paced 0 → 1 phase of company building. You’ll need to strongly believe in our mission, welcome the challenge of ambiguity, and iterate fast.
If this particular role doesn't quite fit your interests, we also have a General Application form on the same careers page. Email: jonas@getnexus.ai
