Build the infrastructure the next decade of AI runs on
We're a team of engineers who like hard physical problems: megawatts, liquid loops, InfiniBand fabrics and the software that turns them into training runs. If that sounds like fun, we'd like to meet you.
Real hardware, real customers, real numbers
Work on the frontier of hardware
Blackwell systems, 800 Gb/s fabrics, 130 kW racks and liquid cooling at scale. You'll touch it, not just read about it.
Small teams, big ownership
Fewer than 200 people run three regions and thousands of GPUs. Everyone owns something that matters.
Climate impact that's measurable
Every GPU-hour we sell displaces a dirtier one somewhere else. We publish the numbers and you'll help improve them.
Competitive pay and equity
Top-of-market salaries, meaningful equity for every employee, and transparent bands.
Remote-friendly
Hubs in San Francisco, Quincy, Montreal and Lulea, with most engineering roles open to remote in the US, Canada and EU.
Benefits that work
Full medical, dental and vision, 401(k) match, parental leave, a learning budget and an annual on-site at one of our facilities.
