CFD Engineer – Propulsion and Battery Systems
General Motors. Lead DFMEA-driven 3D Computational Fluid Dynamics analysis at component, subsystem, and system levels .
About the role
Key responsibilities & impact- Lead DFMEA-driven 3D Computational Fluid Dynamics analysis at component, subsystem, and system levels
- Optimize thermal performance and system reliability across GM propulsion systems
- Identify failure modes, evaluate severity and occurrence risks, and drive risk mitigation strategies
- Perform CFD analysis of high-voltage battery systems and power electronics at cell, module, pack, and system levels
- Simulate battery Thermal Runaway Propagation, venting gas dynamics, and safety physics under severe abuse scenarios
- Lead thermal risk assessments during architecture definition and concept selection using rapid CFD trade studies
- Correlate virtual failure-mode predictions with physical test and validation data
- Communicate analysis plans, assumptions, and results through presentations, reports, and design reviews
- Meet or exceed timing, quality, and cost targets within structured product development processes
- Participate in or lead benchmarking and advanced-methods activities to improve CFD and multi-physics virtual engineering capabilities
Requirements
What you’ll need- 5+ years of experience with simulation, design, testing, or release of propulsion-related systems
- Hands-on experience with at least one commercial 3D CFD software package, such as STAR-CCM+, Simerics-MP+, Fluent, or equivalent
