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
