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.

We are seeking highly motivated and talented experienced engineers to join our team to lead the post-training LLM for autonomous driving. You will be working alongside a world-class team of researchers and engineers to develop and advance the next generation of frontier AI models.

You will: 

  • Post-training for instruction following and CoT thinking: Develop and apply methods to enhance the instruction following and CoT abilities of LLM models targeting autonomous driving applications. This may include fine-tuning strategies, reinforcement learning techniques, or novel approaches to improve LLM’s ability to solve complex driving tasks, make decisions, and interact with dynamic environments.
  • Collaborate deeply with research teams asking the right technical questions, translating research advances into production-ready systems, and shaping joint technical direction.
  • Provide technical leadership to influence senior engineers and researchers across ML, infra, and data teams.
  • Raise the technical bar for how Waymo trains, evaluates, and deploys LLM models in the autonomous driving technical stack.

You have:

  • Demonstrated experience developing post-training methods for LLM models
  • Extensive experience with deep learning frameworks (e.g. PyTorch, JAX) and large-scale model training.
  • A track record of operating effectively under ambiguity, setting direction amid rapidly evolving research and technical constraints
  • The ability to translate research insights into production-ready post-training pipelines and systems
  • Experience applying large language models or foundation models in complex, safety-critical domains (e.g., autonomy, robotics, or other high-reliability systems)
  • Excellent communication and collaboration skills
