Waymo’s simulator is one of the most complex virtual environments ever built. It blends deterministic logic, physical dynamics, and state-of-the-art Generative AI to create a training ground for the Waymo Driver. The Simulator Evaluation team faces the ultimate data challenge: How do you mathematically prove that a virtual world is 'real'? We are looking for a Senior Software Engineer to build the metrics and systems that grade this hybrid environment. You will work at the intersection of software engineering and AI, ensuring that our simulated worlds—whether driven by explicit rules or foundation models—provide a trustworthy representation of reality.

Architect the Eval Rubrik: You will develop novel methodologies to evaluate the simulator across the stack. You will distinguish between true driving challenges and realism artifacts—whether it’s a logic gap, a physics glitch, or a model hallucination.

Build at Scale: You will design and implement high-throughput pipelines (C++/Python) capable of processing massive datasets of simulation logs. You will turn raw, noisy data into clear, actionable signals.

The 'Critic' for the System: You will partner closely with AI research and other simulation teams, as the eval workflows you build will drive rapid innovation and research roadmaps.

Strategic Leadership: You will navigate ambiguity to determine what matters most for realism. You will lead the strategy for specific domains, ensuring our evaluation evolves as fast as our simulation technology.
