Electric Drive SIL Simulation Engineer

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. Were turning todays impossible into tomorrows 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 thefuture of transportation on a global scale.

As an Electric Drive SIL Simulation Engineer you will accelerate the development of GMs 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 conditionswell 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 GMs electric vehicles.
