Actuator Design Engineer

OpenAI OpenAI · AI Frontier · San Francisco, CA · Research

Seeking a Senior Actuator Design and Integration Engineer to lead the development of custom electromechanical actuators for advanced robotic systems. This role involves owning actuator development from concept to prototype validation and system integration, partnering with cross-functional teams. The focus is on precision electromechanical systems, including motors, transmissions, sensing, and thermal architectures, driving development across the full engineering lifecycle and establishing scalable design, test, and integration practices.

What you'd actually do

  1. Lead the architecture, design, and integration of custom robotic actuators, including motors, transmissions, sensing, thermal systems, structural components, and packaging.
  2. Define actuator requirements and system-level trade studies around torque density, bandwidth, efficiency, thermal performance, backdrivability, inertia, reliability, manufacturability, and cost.
  3. Design precision electromechanical assemblies with strong attention to tolerances, alignment, load paths, thermal expansion, sealing, wear, and serviceability.
  4. Drive actuator integration into robotic systems, partnering closely with controls, firmware, electrical, and robotics software teams to optimize closed-loop performance.
  5. Develop and validate prototypes through hands-on bring-up, debugging, characterization, and iterative refinement.
