Job Description
At General Motors, our product teams are redefining mobility. Through a human-centered design process, we create vehicles and experiences that are designed not just to be seen, but to be felt. We’re turning today’s impossible into tomorrow’s standard - from breakthrough hardware and battery systems to intuitive design, intelligent software, and next-generation safety and entertainment features. Every day, our products move millions of people as we aim to make driving safer, smarter, and more connected, shaping the future of transportation on a global scale.
As an Electric Drive SIL Simulation Engineer, you will accelerate the development of GM’s next-generation electric propulsion systems by turning high-fidelity, physics-based models of electric machines, inverters, and full electric-drive systems into a virtual engineering playground. You will build and apply these models to develop, simulate, and verify motor-control algorithms and system behavior across a wide range of operating conditions - well before hardware or dyno assets are available.
In this role, you connect motor-controls theory, electric-drive plant modeling, and advanced SIL environments to enable virtual calibration, automated software verification, and vehicle-level analysis. You will collaborate closely with controls, software, calibration, power electronics, and vehicle teams, using digital twins and virtual test benches to diagnose complex issues, de-risk edge cases, and directly shape the performance, efficiency, and robustness of GM’s electric vehicles.
Major Duties and Responsibilities · Develop, enhance, and maintain physics-based dynamic models of electric drives, including AC machines, three-phase inverters, DC-link behavior, PWM/voltage synthesis, sensing, electromagnetic behavior, losses, nonidealities, temperature effects, parameter variation, and protection limits. · Build models at the appropriate fidelity for control design, algorithm development, SIL co-simulation, and vehicle-level simulation. Apply reduced-order, average-value, or switching representations as appropriate to the use case. · Use MATLAB/Simulink and related modeling tools to evaluate control performance, efficiency, losses, torque response, current quality, robustness, stability, and behavior over the electric-drive operating envelope. · Translate motor, inverter, dyno, and vehicle test data into model parameters and validation cases. Correlate simulation results to measured behavior, identify sources of mismatch, and recommend model or control improvements. · Design and execute simulation test plans, parameter sweeps, corner cases, sensitivity studies, and automated regression tests to evaluate model and controller performance across speed, torque, voltage, temperature, and parameter-variation conditions. · Integrate validated electric-drive models and virtual controllers into SIL/co-simulation environments. Verify interfaces, signal definitions, initialization, execution timing, and model behavior while preserving the intended physics and control fidelity. · Support reuse of common plant models and simulation assets across SIL, HIL, and vehicle-level CoSIM applications in collaboration with Plant Modeling, HIL, Controls, Software, Calibration, and Systems teams. · Document model assumptions, equations, parameter sources, limitations, interfaces, validation evidence, and recommended application boundaries so that models can be used effectively by controls and calibration engineers. · Contribute to continuous improvements in model fidelity, simulation speed, automation, usability, and virtual-development capability. Provide targeted technical support to simulation users as needed.
Basic Qualifications · Bachleors degree in Electrical Engineering, Mechanical Engineering, Computer Engineering, or a related engineering discipline, or equivalent experience. · At least 3 years of relevant experience in electric-machine modeling, motor controls, power electronics, electric-drive simulation, or a combination of these areas. · Strong understanding of AC electric-machine operating principles and three-phase switching power-converter topologies. · Experience developing or using dynamic, physics-based, reduced-order, or control-oriented models of electric drives. · Experience with MATLAB/Simulink for electric-drive modeling, control simulation, data analysis, or algorithm verification. · Understanding of motor-control concepts such as field-oriented control, space-vector or sinusoidal PWM, current regulation, coordinate transformations, torque control, maximum-torque-per-ampere, and flux weakening. · Ability to analyze simulation results, formulate and test hypotheses, and solve complex technical problems using sound engineering methods. · Ability to read and understand embedded C algorithms and software/model interfaces; hands-on embedded software development is helpful but not the primary focus of this role. · Ability to communicate technical information effectively and collaborate with controls, software, calibration, motor, inverter, test, systems, and tools teams. · Ability to work independently, manage priorities, and deliver technically sound results with appropriate documentation.
Preferred Qualifications
- Master of Science degree in Electrical Engineering, Mechanical Engineering, Computer Engineering, or a related engineering discipline, or equivalent experience. · Experience modeling permanent-magnet synchronous machines, induction machines, or other AC machine technologies, including nonidealities, saturation, losses, thermal effects, or parameter identification. · Experience simulating and verifying motor-control algorithms across a broad operating envelope, including high-speed operation, voltage limitation, current limitation, field weakening, and transient events. · Experience correlating electric-drive models to dynamometer, laboratory, HIL, vehicle, or production data. · Experience with automated simulation, parameter sweeps, regression testing, or data analysis using MATLAB scripts, Python, or similar tools. · Experience with SIL, HIL, vehicle-level co-simulation, Functional Mock-up Interface/FMU concepts, or related model exchange and co-simulation standards. · Familiarity with GM electric-drive simulation tools and workflows, such as GMSIM, SIL instrumentation, FMU Studio, or related environments. · Hands-on experience in a high-voltage laboratory, dynamometer, inverter, motor, or electric-drive development environment. · Familiarity with software configuration management and development workflows such as Git, continuous integration, and Agile product development.
