Senior Member of Technical Staff Robot Simulation

Position Summary:

Were looking for a senior hands-on engineer to build and scale the simulation platform for our general-purpose robots. Youll own core simulator and tooling components that let us evaluate and improve policies faster than the real world allows. Youll work closely with autonomy and infrastructure teams to make simulation fast reliable and easy to use.

Core Responsibilities:

• Simulation Development: Build and maintain a high-fidelity simulation platform for prototyping testing and validating robot behaviors.
• Performance & Scalability: Establish benchmarks and optimize rendering physics and pipeline execution to accelerate iteration and increase throughput.
• Evaluation Infrastructure: Build scalable evaluation infrastructure that produces reliable training signals and enables iteration beyond the speed of real-world testing.
• Coverage & Realism: Define measure and reduce the sim-to-real gap while expanding simulation coverage and realism.
• Collaboration & Mentorship: Partner with autonomy and infrastructure teams and mentor simulation engineers.

Required Qualifications:

• Simulation Expertise: Strong background in physics rendering or robotics simulation with hands-on experience developing on platforms such as Isaac Sim MuJoCo or Drake.
• Software & Systems Engineering: Strong Python and/or C skills with experience building and maintaining production-grade high-performance parallel systems.
• Performance & Evaluation Rigor: Ability to profile complex systems diagnose bottlenecks and take a measurement-driven approach to performance reliability evaluation and the sim-to-real gap.
• Technical Leadership: Sound engineering judgment clear communication and a track record of leading workstreams mentoring engineers and raising technical standards.

Preferred Qualifications:

• Experience running containerized simulation workloads in the cloud with scalable parallel job execution.
• Experience generating synthetic simulation assets environments and evaluation scenarios through procedural generation generative modeling or agentic authoring.
• Familiarity with GPU-accelerated simulation or rendering.
