Thermal Systems Simulation Integration Engineer

General Motors•Warren, MI

1d•Hybrid

About The Position

This role involves participating in virtual engineering by developing and executing the integration of full-vehicle cross-functional co-simulation packages. The engineer will develop and integrate co-simulation packages for various vehicle systems including Battery, Driveline, Vehicle Dynamics, Powertrain Cooling, HVAC/Cabin, Energy and Drive Quality, and Electric Drive Unit (DU) models with virtual controllers, software, and calibration. The position requires conducting vehicle-level virtual simulations for powertrain cooling, HVAC cooling, battery pack cooling, electric motors, high voltage power electronics components, and thermal protection. Additionally, the role involves performing vehicle-level energy consumption simulations and implementing suitable energy and thermal control strategies to meet vehicle performance attributes and EPA fuel economy drive cycles, with a focus on BEV programs, process efficiency, and innovation. The engineer will develop and perform 1D and thermal control simulations for new programs, ensure the validity of CFD and 1D models, and align with software release and calibration milestones. Collaboration with other engineering teams, communication of simulation results, and advocacy for virtual methods are key aspects of this role. The position also involves preparing management summaries and reports for senior leadership.
