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 design-including 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

Basic qualifications

- Bachelor's degree or above in Electrical or Mechanical Engineering, or Master's 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)

Preferred qualifications

-

• Master's 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) Amazon is an equal opportunities employer.
