Staff Electromagnetic Design Engineer
As an electromagnetic engineer you will be responsible for the electromagnetic design, modeling, and detailed analysis of high-performance electric motors and actuators. At this role you will additionally focus on developing advanced computational methods, analytical modeling algorithms, and multi-objective optimization tools to improve simulation fidelity and accelerate design iterations. You will work closely with cross-functional teams in Thermal, Mechanical, NVH, Vehicle Integration, and Physical Validation Labs to ensure automotive-grade reliability, efficiency, and cost-down targets. You will provide technical support for component-level testing. You will be responsible to establish simulation-to-test alignment pipelines to continuously improve finite element accuracy and reduce physical prototyping iterations. You will collaborate cross-functionally to resolve manufacturing and production issues. You will provide technical root-cause analysis and support troubleshooting for prototype builds and high-volume production line issues.
