ML Engineer, Simulation Infrastructure

AI · San Francisco / Remote (US) · Full-time · $150k - $260k + equity

Build the simulation environments and infrastructure that support rapid iteration on hand-mocap models. The role covers physics environments, sim-to-real calibration, and data generation at scale.

What you'll do

  • Construct hand-object interaction environments with physically accurate dynamics.
  • Reduce the sim-to-real gap between policies trained in simulation and signal collected in the field.
  • Scale simulation data production for research and training workloads.
  • Collaborate with the AI and collection teams on new training and evaluation tasks.
  • Prototype new sensor configurations in simulation prior to hardware implementation.

What we're looking for

  • 4+ years of professional Python and/or C++.
  • Experience building environments in MuJoCo, PyBullet, Isaac Sim, or similar.
  • Experience improving the performance of physics simulators or rendering pipelines.
  • Discipline around testing infrastructure that maintains correctness as the simulation stack scales.
  • MS or PhD in CS or related field, or equivalent applied experience.

Nice to have

  • Calibration algorithms (extrinsic, intrinsic) for robotics or vision.
  • Differentiable simulation experience.
