Waymo is an autonomous driving technology company with the mission to be the 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 One, a fully autonomous ride-hailing service, and can also be applied to a range of vehicle platforms and product use cases. The Waymo Driver has provided over one million rider-only trips, enabled by its experience autonomously driving tens of millions of miles on public roads and tens of billions in simulation across 13+ U.S. states. Within Perception, the Data Primary team builds and operates the data infrastructure that powers Waymo's perception foundation models. We design scalable pipelines that process petabytes of sensor data and allow everything from rare event mining to large-scale offline model deployment. Our work directly supports model training, evaluation, and production, ensuring that perception models have the high-quality, diverse data they need to perform safely. We collaborate across ML, Simulation, and Infrastructure teams to integrate data into the model lifecycle and help bring new capabilities to the Waymo Driver. In this hybrid role, you will report to an engineering manager. You Will - Design and improve large-scale data pipelines that serve ML and research teams - Deploy and maintain data flows for reliable, high-quality dataset delivery - Apply ML techniques (e.g., embeddings, active learning) for data search and curation - Build tools for scalable data mining and offboard inference - Work to accelerate new model deployment across cities and platforms You Have - C++ programming skills (required), with Python experience - 3+ years of experience with large-scale data systems (e.g., Spark, Beam, or Dataflow) - Background in ML data engineering, data curation, or active learning - Experience building and maintaining end-to-end ML data pipelines - Collaboration skills with model, infra, and product teams We Prefer - Experience with vector search (Faiss, ScaNN) or RAG systems - Knowledge of ML infra for foundation model training and evaluation - Familiarity with data-centric AI (few-shot, fine-tuning, pre-training) - Background in autonomous systems or robotics - MS/PhD or published work in ML or large-scale data systems The expected base salary range for this full-time position across US locations is listed below. Actual starting pay will be based on job-related factors, including exact work location, experience, relevant training and education, and skill level.
