Job summary

Humanoid in Massachusetts is seeking a Robotics Simulation & RL Engineer to design and validate generations of our humanoid platforms using physics simulation and reinforcement learning. You will own URDF models and sustain the simulation-to-hardware pipeline.

Join a team of engineers shaping actuator sizing, sensor layout, and control strategies, with collaboration across mechanical, control, and perception teams. Competitive base salary and equity, with comprehensive benefits.

Qualifications

• M.Sc. or Ph.D. in Robotics, Mechanical Engineering, Control, or related field.
• Strong foundation in robot kinematics and dynamics.
• Experience with robot simulation environments (MuJoCo, Isaac Sim, Gazebo, or similar).
• Experience with reinforcement learning in robotics or physics-based simulation.
• Experience working with URDF or similar robot description formats.
• Strong programming skills in Python and/or C++.
• Experience training RL locomotion or manipulation policies.

Responsibilities

• Design and evaluate new robot platforms using physics simulation.
• Analyze robot capabilities including workspace, manipulability, dynamic balance, and torque limits.
• Use reinforcement learning to stress-test robot designs and explore capability limits.
• Own and maintain URDF models of current and future robot platforms.
• Maintain the CAD → URDF → simulation pipeline.
• Develop tools and benchmarks to evaluate locomotion, manipulation, and platform robustness.
• Provide quantitative feedback to hardware teams on actuator sizing, joint placement, mass distribution, and sensor layout.
• Collaborate with mechanical, control, and perception teams to guide platform design decisions.
