Simulation Engineer

Sunnyvale, CA · Full-time · Onsite

• Build simulation-ready robot parts, tools, and scenes from CAD, descriptions, and scanned or reconstructed scenes. Create reusable assets with consistent scale, coordinate frames, and structure.
• Develop collision representations that preserve task-critical geometry and contact behavior. Choose and tune mesh simplification, convex decomposition, and primitive approximations to balance accuracy, stability, and computation.
• Own measurement of the physical sim-to-real gap. Design matched hardware and simulation tests, quantify differences in motion and contact behavior, and use the results to calibrate mass, inertia, friction, and collision models. Work with hardware and robotics engineers to collect reference measurements and track improvements.
