Motor Electromagnetic Design Engineer

About the company

Our client is a robotics company.

The role

Raydar is recruiting for this role on behalf of our client. Own the electromagnetic side of motor development, from early sizing and concept work through prototype testing. Partner with colleagues across hardware disciplines so the machine meets its performance goals within real packaging and electrical limits.

What you'll do

- Compare motor layouts and size core materials to meet torque, speed, efficiency and weight targets.

- Specify slot and pole counts, winding arrangements, magnets, laminations and air gaps, and assess saturation, losses, cogging and torque ripple.

- Build electromagnetic finite element models and analytical checks, recording assumptions and sensitivity to production variation.

- Align motor geometry with thermal and mechanical colleagues on heat flow, retention, clearances and manufacturability.

- Coordinate with drive and firmware engineers on motor parameters, voltage, current limits and operating ranges before design release.

- Support suppliers and prototype builds, and test motors on the bench or dynamometer to match measured results with predictions.

Requirements

What we're looking for

- Able to work on-site in Fremont, California.

- Hands-on work with compact, high-torque motor designs of the kind used in robotics, actuators, aerial vehicles or electric cars.

- Electromagnetic design experience with permanent magnet synchronous or brushless DC motors.

- Proficiency with electromagnetic or finite element design software.

- Prior work on electrified drivetrains where efficiency was a central goal.

- Solid knowledge of coil layout, flux paths, magnet and steel behavior, sources of energy loss and torque generation.

- Comfortable scripting in Python or MATLAB to run parameter studies, analyze data and tie simulations to test results.

Bonus points

- Background in refining supplier-built motor components or assembly processes.
