Job summary
Responsibilities
We are seeking a Mechanical Design Engineer to lead the development of motor mechanical designs and prototype hardware for advanced robotic systems. You will own stator and rotor mechanical development from early concepts and detailed design through hands-on builds and prototype validation…
- Own stator and rotor mechanical designs and released CAD and drawings, including geometry, interfaces, fits, tolerances, retention, assembly access, and mechanical validation.
- Develop laminations, stack assembly methods, bobbins, and winding interfaces that control alignment, insulation, conductor placement, and end-turn packaging.
- Design, fabricate, and debug fixtures for winding, stacking, assembly, alignment, and inspection.
- Build and troubleshoot prototypes. Use 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 that let technicians reproduce…
What they're looking for
- 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, with 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.
