Waymo is looking to solve the problem of improving access to mobility while saving thousands of lives lost to traffic crashes by building the Waymo Driver—The World's Most Experienced Driver™, and the Simulation ML Infrastructure team is focused on building scalable AI/ML infrastructure to accelerate the Simulator team in sustainably innovating and building state of the art simulations of realistic environments for the testing and training of the Waymo Driver.

Requirements

  • 5+ years of professional software engineering experience, with at least 3 years in machine learning infrastructure such as developing, designing, scaling, training, deploying, and optimizing large-scale machine learning systems from data to model.
  • Solid experience in the development and optimization of machine learning infrastructure tools like DeepSpeed, PyTorch, TensorFlow, Ray, or similar frameworks.
  • Strong understanding of state-of-the-art machine learning models and algorithms such as autoregressive transformers and familiarity scaling large models across ML accelerator profiling tools to uncover performance bottlenecks.
  • Practical familiarity in Autonomous Driving, Simulations, and ML accelerators is a plus.
  • Experience with massive model scaling, ML accelerators, and large-scale distributed systems.
  • Experience with designing and scaling AI/ML infrastructure for multi-billion parameter foundation models in ML accelerator-friendly simulations.
  • Familiarity with large foundation models trained on massive datasets to model the real world.

Responsibilities

  • Be part of a world-class, high-performing research engineering team to advance the state of the art of ultra realistic multi-agent simulations using foundation models.
  • Collaborate closely with the core Waymo Realism Modeling team in London and Waymo Oxford to use large foundation models to improve sim realism.
  • Work at the intersection of data engineering, model development, and simulations, and drive architectural decisions.
  • Own large, complex systems, driving architectures and designs that meet technical and business objectives.
  • Design and scale large distributed systems covering the ML lifecycle, supporting planet-scale dataset generation, model training, and evaluation.
  • Collaborate cross-functionally to derive performance and system-level requirements for large ML systems.
  • Translate product/business goals into measurable technical deliverables, ensuring system component alignment.

Other

  • Excellent communication skills, both verbal and written, with the ability to translate complex technical concepts for a broad audience.
  • Strong leadership skills with experience driving ambiguous problems end-to-end, with a willingness and independence to pick up whatever knowledge to get the job done.
  • Passionate about building infrastructure, libraries, tools, and pipelines for engineers and scientists.
  • Ability to work in a world-class, high-performing research engineering team.
  • Eligibility to participate in Waymo’s discretionary annual bonus program, equity incentive plan, and generous Company benefits program, subject to eligibility requirements.
