Machine Learning Engineer, Runtime & Optimization

Cobalt Streamworks is an autonomous driving technology company with the mission to be the world's most trusted driver. Since its start as the Google Self-Driving Car Project in 2009, Cobalt Streamworks has focused on building the Cobalt Streamworks Driver—The World's Most Experienced Driver™—to improve access to mobility while saving thousands of lives now lost to traffic crashes. The Cobalt Streamworks Driver powers Cobalt Streamworks’s fully autonomous ride-hail service and can also be applied to a range of vehicle platforms and product use cases. The Cobalt Streamworks Driver has provided over ten million rider-only trips, enabled by its experience autonomously driving over 100 million miles on public roads and tens of billions in simulation across 15+ U.S. states. The ML Platform team at Cobalt Streamworks provides a set of tools to support and automate the lifecycle of the machine learning workflow, including feature and experiment management, model development, optimization and monitoring. These efforts have resulted in making machine learning more accessible to teams at Cobalt Streamworks, including Perception, Planner, Research and Simulation. We are looking for engineers with ML software or ML systems expertise to help us improve compute performance on both cloud and car. You'll work across the entire ML stack from the system perspective, from efficient deep learning models, model compression, ML software (e.g. JAX, XLA, Triton, and CUDA), to .
