Mechanical Design Engineer, Motor Design & Prototyping

• Lead development of motor mechanical designs and prototype hardware for advanced robotic systems
• Own stator and rotor mechanical development from early concepts and detailed design through hands-on builds and prototype validation
• Own released CAD and drawings, including geometry, interfaces, fits, tolerances, retention, assembly access, and mechanical validation
• Develop laminations, stack assembly methods, bobbins, and winding interfaces
• Design, fabricate, and debug fixtures for winding, stacking, assembly, alignment, and inspection
• Build and troubleshoot prototypes using measurements, defects, rework, and assembly effort to improve designs and processes
• Establish low-volume prototype production with equipment, build sequences, work instructions, revision control, traceability, and acceptance checks
• Test new manufacturing methods and winding approaches
• Collaborate with electromagnetic, electrical, manufacturing, and test engineers to resolve motor performance, packaging, buildability, and validation tradeoffs

• Experience designing and building motors, actuators, or other precision electromechanical assemblies
• Experience with lamination stacks, bobbins, winding, insulation interfaces, or small-component assembly
• Proficiency in 3D CAD, manufacturing drawings, tolerance analysis, and fixture design
• Hands-on metrology and inspection of critical mechanical interfaces
• Experience with machining, additive manufacturing, bonding, or other prototype manufacturing processes
• Experience turning an initial build into a repeatable low-volume process
• Interest in using AI to reduce repetitive design and prototype work, with careful engineering review
• Ability to work in person in San Francisco, CA, 4 days a week
