AerospaceAir TransportationCommercial
Responsibilities
Lead electromagnetic design of propulsion motors and high-speed PM generators, from concept through prototype validation
Develop and refine EM models (FEA in JMAG, parametric studies in MATLAB) to predict torque, efficiency, losses, inductances, and operating limits
Translate propulsion system requirements into machine performance specifications, ensuring alignment with aircraft integration needs
Evaluate design trade-offs in topologies, winding schemes, materials, and manufacturability, capturing these effects in models
Provide validated machine models and parameter sets to inverter, controls, thermal, and mechanical teams for system-level integration
Support machine test planning and correlation of measured performance with simulations; update models to maintain accuracy
Deliver specifications, analyses, and verification evidence with clear documentation and traceability
Qualification
Required
BS/MS in Electrical Engineering with 5–7 years of experience in motor/generator EM design
Demonstrated expertise in permanent-magnet machine design, including torque production, flux distribution, inductance modeling, and loss analysis
Proven ability to build high-fidelity FEA models in JMAG and automate studies/optimizations in MATLAB
Strong understanding of electromagnetic phenomena: saturation, harmonics, torque ripple, eddy-current and core losses, and demagnetization effects
Experience reconciling analytical/FEA predictions with test data, and refining models based on hardware correlation
Awareness of how manufacturing factors (slot fill, end turns, lamination quality, tolerances, magnetization variation) impact machine performance and how to account for them in design
Ability to communicate EM design requirements and trade-offs clearly to mechanical, thermal, and power-electronics engineers
Strong technical writing, analysis reporting, and documentation skills
Preferred
Experience designing high-speed machines and understanding their EM and mechanical coupling challenges
Familiarity with additional EM tools (Motor-CAD, ANSYS Maxwell, Flux, COMSOL)
Understanding of insulation systems, partial-discharge considerations, and EMI/EMC impacts on machine design
Exposure to aerospace or automotive development practices, including requirements flowdown, verification, and environmental testing
Track record delivering production-ready EM designs and correlated models in fast-paced hardware programs
