Description Role As a CFD Engineer - Propulsion and Battery Systems, you will lead DFMEA-driven 3D Computational Fluid Dynamics (CFD) analysis at the component, subsystem, and system level to optimize thermal performance and system reliability across GM propulsion systems. Operating within a DFMEA-centric environment, you will use virtual engineering to identify failure modes, evaluate severity/occurrence risks, and drive robust risk mitigation strategies for propulsion systems, specifically battery and power electronics thermal performance, durability and safety requirements. Work Arrangement Hybrid work position: This position does not require an employee to be on-site full-time to perform most effectively. The employee's role enables them to work at a GM facility or off- site as frequently as needed or desired. Primary Responsibilities • Perform DFMEA-aligned 3D CFD analysis focusing on high-voltage battery systems and power electronics to identify and mitigate critical thermal failure modes at the cell, module, pack, and system level. • Simulate and quantify battery Thermal Runaway Propagation (TRP), venting gas dynamics, and safety physics under severe abuse scenarios to validate DFMEA mitigation designs, barrier integrity, and failure containment controls. • Lead thermal risk assessments during early architecture definition and concept selection using rapid CFD trade studies to eliminate high-risk failure modes prior to design freeze. • Correlate virtual failure mode predictions with physical test and validation data to ensure simulation fidelity in predicting real-world failure thresholds and reliability margins. • Clearly and effectively communicate analysis plans, assumptions, and results to internal and external stakeholders using presentations, reports, and design reviews. • Meet or exceed timing, quality, and cost targets within structured product development processes. • Participate in and/or lead benchmarking and advanced methods activities to continuously improve GM's virtual engineering capabilities in CFD and multi- physics analysis. Required Skills and Experience • 5+ years of experience with simulation, design, testing, or release of propulsion- related systems (e.g., engines, transmissions, e-drive units, batteries, power electronics, thermal management systems). • Hands-on experience with at least one commercial 3D CFD software package (e.g., STAR-CCM+, Simerics-MP+, Fluent, or equivalent). • Demonstrated understanding of heat transfe
