Thermal Systems Simulation Integration Engineer

Description
Work Arrangement
This role is categorized as hybrid. This means that a successful candidate will be expected to report to Warren, MI three times a week at a minimum or at a frequency dictated by the business.
The Role
The Thermal Systems Simulation Integration Engineer is responsible for leading the move to virtual engineering by leading the integration of full-vehicle cross-functional co-simulation packages that excel for Thermal Systems and related disciplines. This position is highly collaborative, involving partner teams throughout VDDV, Vehicle Performance, Validation, SMT's and VMEC. This is an emerging technology and constant innovation key to success.
What You'll Do (Responsibilities)

• Spearhead full-vehicle co-simulation integration for ICE, HEV, and BEV models using GT-Suite, MATLAB/Simulink, AMESIM, CarSim, and CarMaker.
• Develop cross-functional packages incorporating Battery, Driveline, Vehicle Dynamics, Thermal Systems, Electric Drive Unit, and Driver models with software and calibration.
• Conduct virtual simulations for cooling systems (powertrain, HVAC, battery, e-motor, power electronics) and validated thermal protection strategies.
• Lead energy consumption simulations and implemented controls to meet performance targets and EPA fuel economy cycles.
• Deliver 1D and thermal control simulations tailored to program-specific functional and behavioral objectives.
• Enable Virtual Buy-Off Ride assessments (65%, 80%, 99%) and led issue resolution by mobilizing simulation partners.
• Verify CFD and 1D model accuracy using geometry from Teamcenter and RTC; utilize STAR-CCM+, FLUENT, SIMERICS, Kuli, AVL-CRUISE, and more.
• Ensure alignment with software calibration milestones and maintained simulation package currency.
• Champion virtual methods for vehicle design, validation, and development across engineering disciplines.
• Identify strategic innovation opportunities and advanced simulation procedures for speed and fidelity.
• Enforce governance standards, documentation, and deployment via Git, SVN, and TFS version control systems.
• Advocate for thermal systems within cross-functional simulation teams.
• Guide vehicle design through scenario analysis and simulation-led recommendations; generated reports for executive leadership.
