Senior Staff Machine Learning Performance Engineer

The Mission: We are building the next generation of end-to-end autonomous driving on physical AI foundation models — vision-language-action policies and world models — and the same training stack carries our robotics program. These training runs span thousands of accelerators and days of wall-clock — how fast we train them is how fast we learn. As a Senior Staff Machine Learning Performance Engineer, you will own that speed: working with the modeling teams on their hardest bottlenecks, setting the technical direction for performance, and turning one-off wins into defaults — including the agentic workflows that find the next round of them automatically.
