SDE Robotics and Physics Simulation, Frontier AI Robotics

In this role you will act as the primary specialist for physics engine internals and dynamics developing high-fidelity vectorized simulation environments for robotics locomotion navigation and interaction/manipulation. You will collaborate with hardware engineers to validate robot models and partner with research scientists to ensure numerical stability and physical accuracy for Sim2Real transfer. Your work focuses on tuning solvers optimizing collision dynamics and performing system identification to enable the training of robust robot control policies for complex physical interactions.

Key job responsibilities
* Develop and maintain the shared simulation software framework specifically owning the physics integration robot state management and control layers
* Develop and optimize parallelized (vectorized) physics environments for high-throughput reinforcement learning (e.g. Isaac Lab MuJoCo)
* Tune physics engine parameters (solvers friction restitution) to support complex contact-rich scenarios required for dexterous manipulation and agile locomotion.
* Implement and validate complex robot models (URDF/MJCF) involving precise actuator and sensor modeling
* Collaborate with robot engineers and scientists to perform System Identification (SysID) to minimize the Sim2Real gap

About the team
At Frontier AI & Robotics (FAR) were not just advancing robotics were reimagining it from the ground up. Our team is building the future of intelligent robotics through frontier foundation models and end-to-end learned systems. We tackle some of the most challenging problems in AI and robotics from developing sophisticated perception systems to creating adaptive manipulation strategies that work in complex real-world scenarios.

What sets us apart is our unique combination of ambitious research vision and practical impact. We leverage Amazons massive computational infrastructure and rich real-world datasets to train and deploy state-of-the-art foundation models. Our work spans the full spectrum of robotics intelligence from multimodal perception using images videos and sensor data to sophisticated manipulation strategies that can handle diverse real-world scenarios. Were building systems that dont just work in the lab but scale to meet the demands of Amazons global operations.

Join us if youre excited about pushing the boundaries of whats possible in robotics working with world-class researchers and seeing your innovations deployed at unprecedented scale.
