Solve the hardest problems in compute.
We write the compiler, the kernels and the runtime that decide whether a training run costs 1x or 7x.
Small team. Hard systems problems.
Small team, San Francisco, everyone close to the metal.
Technical depth isn't optional. Everyone here reads kernel traces, including the people who don't write them. No matter your role, you'll be expected to engage deeply with the technology.
