Preferred Qualifications * Practical experience in Reinforcement Learning (RL), Sim2Real transfer, or Robotics. * Experience with distributed ML frameworks and accelerators like GPU/TPU. * Domain familiarity with Autonomous Driving systems, multi-agent simulations, or realistic world modeling. ## Description Join our ML Infrastructure engineering team advancing state-of-the-art ultra-realistic multi-agent simulations using foundation models. In this role, you will work at the intersection of ML infrastructure, foundation models, and simulation engineering, with a specific focus on writing high-performance business and simulation logic in JAX/TensorFlow running directly on TPUs to power realistic environments for Reinforcement Learning (RL). What You'll Do * Design, build, and optimize realistic simulation environments and business logic running on TPUs using JAX and TensorFlow. Implement and optimize large-scale model and data parallelism strategies for training and running foundation models on TPU hardware. * Collaborate closely with modeling teams to integrate foundation models into simulation pipelines. * Drive technical architectures and system designs from data engineering through simulation execution to meet business and performance objectives. * Profile systems, identify performance bottlenecks across ML accelerators, and optimize end-to-end execution speed. * Translate product and business goals into concrete technical requirements and system deliverables.
