We combine hardware and software into a plug-and-play platform for developers, researchers and enterprises, with an open ecosystem that supports the development of physical AI.\nThe Role\nWe are looking for a Motor Electromagnetic Design Engineer to develop PMSM and BLDC motors for integrated robot actuators. You will own the electromagnetic design from topology and sizing through prototype characterization, working with mechanical, thermal and drive engineers to deliver performance within the actuator’s real packaging, voltage, current and duty-cycle limits.\nResponsibilities\nEvaluate motor topologies and size active materials for required torque-speed performance, efficiency and mass, including frameless or outrunner configurations where appropriate.\n\nDesign slot and pole combinations, winding layouts, magnets, laminations and air gaps; evaluate saturation, losses, cogging torque and torque ripple.\n\nBuild electromagnetic FEA models and analytical checks; document assumptions, material properties and sensitivity to manufacturing tolerances.\n\nCo-design the motor with thermal and mechanical engineers, accounting for heat paths, retention, clearances, assembly and manufacturability.\n\nWork with drive and firmware engineers on motor parameters, bus voltage, current limits, back-EMF and operating envelopes before design release.\n\nSupport suppliers and prototype builds; characterize motors on the bench or dynamometer and correlate measured constants, torque, efficiency and temperature to predictions.\n\nMinimum Qualifications\nHands-on electromagnetic design experience with PMSM or BLDC motors, including a design that was built and experimentally characterized.\n\nStrong understanding of winding design, magnetic circuits, materials, loss mechanisms and torque production.\n\nProficiency in an electromagnetic design or FEA tool such as Motor-CAD, JMAG, Ansys Maxwell, Flux or an equivalent workflow.\n\nAbility to connect simulation to test data and work directly with mechanical, thermal, inverter and manufacturing engineers.\n\nPreferred Qualifications\nExperience with frameless, outrunner, high torque-density or low-cogging motors for robotics, servos, drones or EV traction.\n\nExperience optimizing winding manufacture, magnet retention, lamination production or motor assembly with suppliers.\n\nPython or MATLAB for design sweeps, data analysis and model correlation.","description_format":"text","description_chars":2506,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Robotics
