The VTM‑1D Thermal VDDV Engineer is responsible for the execution of 1D thermal system modeling and virtual validation in support of General Motors’ current and future vehicle programs. This role applies independent technical judgment to non‑routine engineering challenges and supports the continued advancement of GM’s vehicle thermal virtual development and validation (VDDV) capabilities. The position operates under general supervision, independently completing most standard work and escalating complex issues as appropriate. Impact is primarily within the vehicle thermal VDDV domain, with periodic cross‑functional collaboration across adjacent engineering teams.
Job Responsibility:
Execute 1D thermal system simulations to support vehicle thermal sizing, development, and virtual validation
Support design decisions through technical influence and data‑based recommendations
Apply knowledge of thermal physics, system behavior, and component interactions to identify issues and recommend solutions
Independently select appropriate analysis methods within established procedures, standards, and guidelines
Support development, enhancement, and application of VDDV tools, methods, and standard work aligned with an “all‑virtual” development approach
Contribute to capability growth in areas such as model robustness, modularization, optimization, and data‑driven methods
Apply established and emerging techniques to improve model accuracy, efficiency, and repeatability
Collaborate with System and Module Teams, thermal component and subsystem suppliers, propulsion systems teams, validation, calibration, and software development teams
Identify and propose opportunities for process improvement, efficiency gains, and risk reduction within the VDDV workflow
Proactively anticipate needs within own work area and escalate potential issues or roadblocks when necessary
Communicate analysis results, risks, and recommendations clearly to peers and leadership
Provide technical guidance and training to less experienced engineers on analysis tools, methods, and standard practices
Serve as a technical resource within the VTM‑1D thermal VDDV team while continuing to learn from senior subject‑matter experts
Requirements:
Bachelor’s or master’s degree in Engineering
2+ years of experience in powertrain cooling or A/C system analysis
1D thermal system modeling experience
Strong understanding of thermal systems and components, including performance integration and model assumptions/limitations
Demonstrated ability to independently resolve routine technical problems within established engineering frameworks
Proficiency with GT‑Power, MATLAB, and related system modeling tools
DFSS Black Belt certification
Strong interpersonal and communication skills with the ability to collaborate effectively across functions
