Principal Software Engineer - Waymo Driver Post Training

Waymo 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, Waymo has focused on building the Waymo Driver—The World's Most Experienced Driver™—to improve access to mobility while saving thousands of lives now lost to traffic crashes. The Waymo Driver powers Waymo’s fully autonomous ride-hail service and can also be applied to a range of vehicle platforms and product use cases. The Waymo 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 Perception team at Waymo builds technology that powers the Waymo Driver. Our models allow the Waymo Driver to perceive the world around it, make the right decision for every situation, and deliver people safely to their destinations. We conduct research to address real-world problems and collaborate with research teams at Alphabet. We have access to millions of miles of driving data from a diverse set of sensors, allowing ML practitioners like you to develop multi-modal models and techniques at scale. In this hybrid role, you will report to our Senior Director of Engineering, Perception. You Will Work closely with Onboard model engineers on rapid prototyping and experiments, to verify model design and training recipes, before decision to productionize Whenever needed, prototype the necessary infrastructure (data, eval) to enable model experimentation Drive post-training technology roadmap (e.g., RL techniques) and training recipe roadmap Drive and contribute to the production rollout of major model architecture and recipe evolutions, to solve a variety of behavior contexts Build and facilitate strong collaborations between Onboard and research teams across Waymo and Alphabet Work closely with Onboard and collaborators to build and continuously evolve the post-training recipe roadmap, with milestones towards strong capability goals and continuous production impact You Have Remaining technical and hands-on, either currently as an individual contributor, or leading a small team Actively writes code, reviews code, and runs experiments Hands-on experience in post-training techniques, e.g., RL and SFT Experience in at least one of Robotics, VLA, VLM.
