What you need
- Master’s degree or PhD in electrical engineering, mechanical engineering, applied physics, or a related field with a focus on electric machines, electromagnetics, optimization, or electric powertrains
- Strong understanding of electric-machine fundamentals including magnetic circuits, winding theory, d-q models, saturation, harmonics, losses, thermal effects, and permanent-magnet behavior
- Significant experience developing and interpreting finite-element and reduced-order models of electric machines
- Experience with Motor-CAD or similar software (JMAG, Maxwell, COMSOL, etc.) for electromagnetic, thermal, and performance modeling of electric machines
- Strong proficiency in MATLAB for model development, automation, optimization, data analysis, and visualization
- Experience generating motor maps or reduced-order models for system simulation, controls, or powertrain optimization
Nice to have
- Experience with aerospace, electric aviation, robotics, automotive traction, or other mass- and efficiency-constrained applications
- Experience optimizing multiple motor types across a common vehicle or product platform
- Experience with Motor-CAD (or similar software) python scripting, MATLAB-based optimization workflows, and automated generation of large motor design spaces
- Familiarity with additional electromagnetic tools such as Ansys Maxwell, JMAG, etc.
- Knowledge of motor-control techniques, inverter limitations, field weakening, sensorless control, and fault-tolerant operation
Worth weighing
- No salary listed
- Role involves significant cross-functional collaboration and technical ownership
- Focus on developing a reusable modeling and validation foundation, which may involve complex problem-solving and ambiguity
