Motor Design Engineer , Amazon Robotics

Amazon is seeking a talented and motivated Motor Design Engineer to own the electromagnetic design analysis and production design-for-manufacturing of high-performance cost-efficient electric motors and integrated actuator systems for our next-generation robotic platforms at substantial scale.

The ideal candidate will have deep expertise in electric motor designincluding brushless DC (BLDC) permanent-magnet synchronous motors (PMSM) and vast experience with motor-manufacturing techniques and a proven ability to manage external motor equipment vendors and contract design partners. This candidate must combine strong analytical skills with hands-on experience bringing precision motor and actuator systems from concept through volume manufacturing and thrive in a fast-paced highly collaborative environment.


Key job responsibilities
Design model and optimize electric motors (BLDC PMSM frameless BLDCs in various configurations such as radial axial and transversal flux) for high-torque-density robotic joint actuators
Perform electromagnetic FEA (JMAG Ansys Maxwell MotorCAD or equivalent) to predict performance losses cogging torque and thermal behavior
Own development of novel manufacturing-focused motor concepts based on well-established motor principles
Develop design-for-manufacturing specifications (winding process steel stamping magnet sintering & magnetization etc.) to enable cost-efficient volume production while maintaining tight performance tolerances
Collaborate closely with gear mechanical controls and firmware engineers to deliver fully integrated actuator modules
Own vendor relationships for motor lamination stacks winding houses magnet suppliers and contract motor design partners
Define and validate motor test protocols (back-EMF torque-speed curves thermal characterization efficiency maps torque-ripple artefacts core losses etc.)
Drive continuous improvement in motor cost efficiency torque density and reliability across product generations
Generate and maintain detailed motor specifications drawings and design documentation


- Bachelors degree or above in Electrical or Mechanical Engineering or Masters degree in Electrical or Mechanical Engineering
- Experience with electrical theory robotics controls components and automated equipment or experience in the mechanical or controls field
- Experience interpreting and modifying mechanical and electrical drawings
- Experience managing external vendors and co-design partnerships for motor components (laminations windings magnets)
- Experience with motor design and electromagnetic FEA software (JMAG Ansys Maxwell MotorCAD SPEED or equivalent)

- Masters degree or PhD in Electrical Engineering or Mechatronics with a focus on electric machine design
- Experience designing compact high-torque-density frameless or integrated motors for robotics or aerospace applications
- Familiarity with IEC NEMA or other motor standards and rating methods
- Experience with highly integrated actuator designs combining motor gear sensor and drive electronics in a single module
- Knowledge of advanced magnet materials (NdFeB SmCo) demagnetization analysis and magnet supply chain considerations
- Experience with thermal management of compact motor assemblies (potting liquid cooling thermal path optimization)
