Hybrid Position: This role is categorized as hybrid. The successful candidate is expected to report to either the Markham Elevation Centre (MEC) or Oshawa Elevation Centre (OEC) at least three times per week.

The Role

• The Thermal Systems Simulation Integration Engineer leads the transition to virtual engineering by integrating full-vehicle cross-functional co-simulation packages focused on Thermal Systems and related disciplines. This highly collaborative role involves working with partner teams across VDDV, Vehicle Performance, Validation, SMTs, and VMEC. It is an emerging technology that requires constant innovation.

Responsibilities

• Lead full-vehicle co-simulation integration for ICE, HEV, and BEV models using tools like GT-Suite, MATLAB/Simulink, AMESIM, CarSim, and CarMaker.
• Develop cross-functional simulation packages including Battery, Driveline, Vehicle Dynamics, Thermal Systems, Electric Drive Unit, and Driver models with software and calibration.
• Perform virtual simulations for cooling systems (powertrain, HVAC, battery, e-motor, power electronics) and validate thermal protection strategies.
• Lead energy consumption simulations and implement controls to meet performance targets and EPA fuel economy standards.
• Deliver 1D and thermal control simulations aligned with program-specific objectives.
• Support Virtual Buy-Off Ride assessments (65%, 80%, 99%) and coordinate issue resolution with simulation partners.
• Verify CFD and 1D model accuracy using geometry from Teamcenter and RTC; utilize STAR-CCM+, FLUENT, SIMERICS, Kuli, AVL-CRUISE, among others.
• Ensure alignment with software calibration milestones and maintain updated simulation packages.
• Promote virtual methods in vehicle design, validation, and development across engineering teams.
• Identify innovation opportunities and improve simulation fidelity and speed.
• Maintain governance, documentation, and deployment standards using Git, SVN, and TFS.
• Advocate for thermal systems within cross-functional simulation teams.
• Guide vehicle design through scenario analysis, provide simulation-led recommendations, and prepare reports for leadership.

Required Qualifications

• BS in Mechanical, Electrical, Software Engineering, Computer Science, or related field.
• Minimum 5 years of relevant experience.
• Experience in Thermal Systems modeling and integrating VECU, software, and calibration.
• Ability to characterize thermal systems using CFD tools like STAR-CCM+, FLUENT, SIMERICS, and develop 1D models.
• Familiarity with CAE tools such as GT-Power, AMESIM, CarSim, CarMaker, MATLAB/SIMULINK.
• Experience with system data management tools like Teamcenter and RTC.
• Proficiency with version control systems like Git, SVN, TFS.
• Strong teamwork, communication, and practical problem-solving skills.

Preferred Qualifications

• MS in Mechanical, Electrical, Software Engineering, or Computer Science.
• Over 10 years of relevant experience.
• Automotive experience, including building, restoring, modifying, or performance driving.
• Participation in automotive teams such as Mini-Baja, Formula SAE, PACE, Eco-Car.
