GM Performance Power Units - Concord, NC

Electromagnetic Simulation Engineer - Onsite

Job Summary

GM Performance Power Units (GM PPU) is seeking a skilled and motivated Electromagnetic Simulation Engineer to join our innovative engineering team in Concord, NC. This role focuses on electromagnetic (EM) simulation, analysis, and optimization of MGU-K electric motors and power electronics for Formula 1 power units. The engineer will support design teams by providing high-fidelity EM modeling to optimize performance, efficiency, losses, thermal loads, and manufacturability.

Key Responsibilities

Develop and execute 2D/3D electromagnetic finite element analysis (FEA) models for high power, high speed electric motors using tools like JMAG, Motor-CAD, Ansys Maxwell, or Flux.
Perform performance mapping, torque-speed curves, field-weakening analysis, efficiency maps, and loss calculations (copper, iron, eddy current, PM losses).
Analyze and optimize designs for high-speed operation (60k+ RPM), high power density, thermal management, and manufacturability constraints.
Support transient and harmonic analyses for inverter switching effects, PWM harmonics, and electromagnetic forces.
Collaborate with mechanical, thermal, controls, and manufacturing teams to integrate EM results into holistic motor design.
Validate simulation results against test data and support motor prototype development and testing.
Document analysis methods, results, and recommendations in technical reports and design reviews.
Stay current with latest EM simulation methodologies and industry best practices.

Required Qualifications

Bachelor’s degree in Electrical Engineering, Mechanical Engineering, or related technical field; Master’s degree preferred.
3-7 years of experience in electromagnetic simulation for electric motors or machines.
Proficiency with commercial EM FEA tools (JMAG, Ansys Maxwell, Motor-CAD, Flux, or equivalent).
Strong understanding of electric machine theory, including PMSM/IPMSM design principles, field-weakening, reluctance torque, and loss mechanisms.
Experience with performance mapping, efficiency optimization, and thermal-electromagnetic coupling.
Proficiency in Python, MATLAB, or similar for post-processing, automation, and data analysis.
Ability to work collaboratively in cross-functional teams and communicate technical results effectively.

Desirable Skills

Experience in motorsport, F1, high-performance EV, or aerospace electric motor applications.
Knowledge of power electronics integration effects on motor performance (inverter harmonics, switching losses).
Familiarity with advanced motor topologies (axial flux, hairpin windings, variable flux) and high-speed rotor design.
Experience with parametric optimization, DOE, and machine learning-assisted design workflows.
Understanding of manufacturing impacts on EM performance (winding factors, material properties, tolerances).
Experience correlating simulation with dyno/test data and supporting root cause analysis.

Personal Attributes

Analytical mindset with strong problem-solving skills and attention to detail.
Proactive and self-motivated with ability to manage multiple priorities.
Team player comfortable working in fast-paced, high-performance engineering environment.
Passionate about electric machine design and motorsport technology.
Effective communicator who can translate complex EM concepts to non-specialists.
