Mechanical Design Engineer, Motor Design & Prototyping
San Francisco, Remote. Posted 2 months ago
The role
You will lead the development of motor mechanical designs and prototype hardware for advanced robotic systems. This involves owning stator and rotor mechanical development from early concepts through hands-on builds and validation.
What you will do
- Own stator and rotor mechanical designs and released CAD and drawings
- 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
- Establish low-volume prototype production with equipment, build sequences, and work instructions
- Test new manufacturing methods and winding approaches
- Work with electromagnetic, electrical, manufacturing, and test engineers to resolve tradeoffs
Required qualifications
- Move comfortably between CAD, the shop, measurements, and hands-on builds
- Understand how tolerances, insulation, tool access, and assembly sequence affect motor build and use
- Diagnose failed builds through evidence and focused experiments
- Build useful processes while designs evolve and document them
Nice to have
- 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
- 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
Before you apply
- Background checks for applicants will be administered in accordance with applicable law
