Thermal Execution Virtual Design Development & Validation Engineer - Front End Airflow and Calibration Support

Description
At General Motors, our product teams are redefining mobility. Through a human-centered design process, we create vehicles and experiences that are designed not just to be seen, but to be felt. We're turning today's impossible into tomorrow's standard -from breakthrough hardware and battery systems to intuitive design, intelligent software, and next-generation safety and entertainment features.
Every day, our products move millions of people as we aim to make driving safer, smarter, and more connected, shaping the future of transportation on a global scale..
The Role
The Thermal Execution Virtual Design Development Validation (VDDV) team uses advanced Computational Fluid Dynamics (CFD) to drive vehicle development for both Electric Vehicles (EVs) and Internal Combustion Engine (ICE) products. The team leads integrated Front End Airflow (FEAF) solutions, underhood/underbody thermal protection strategies, and is expanding capabilities in transient simulation and virtual validation. This is an exciting opportunity to join a team operating on the front edge of GM's virtual development transformation.
As a Thermal Execution VDDV Engineer - FEAF & Calibration Support, you will build, run, and interpret results from front-end airflow models. You will also partner directly with the Airflow Calibration team to develop virtual calibration processes and deliver simulation-based data required for FEAF calibration milestones. This role is central to enabling fully virtual calibration workflows that reduce physical testing and improve development efficiency. You will operate within a multi-disciplinary team performing thermal and fluid flow simulations that influence vehicle architecture, propulsion design, and overall thermal performance.
What You'll Do

• Perform vehicle-level CFD simulations to evaluate front-end airflow and thermal performance
• Execute propulsion-focused CFD simulations under various load cases to guide propulsion system and component design
• Develop CFD simulations for new programs based on propulsion/vehicle content and performance objectives
• Drive simulation efficiency and innovation for future vehicle and propulsion programs Collaborate with Propulsion PMTs, Thermal/HVAC Engineering, Aero Performance, Studio, and Design Release Engineers to communicate results and make design recommendations
• Partner with FEAF Calibration teams to develop virtual calibration processes and procedures
• Provide data packages required to support FEAF calibration milestones
• Participate in Thermal Development Performance Integration Team (PIT) meetings
• Use CIT and PDT forums to resolve issues when necessary Engage with test engineers in the Climatic Wind Tunnel, Aerodynamics Tunnel, and Proving Grounds to correlate models with physical testing and refine analytical methods
• Travel as required

Your Skills & Abilities (Required Qualifications)

• Bachelor's degree in mechanical engineering (Thermal Sciences emphasis) or Aerospace Engineering required
• 5+ years of experience in thermal and fluid flow engineering or related Sciences
• Hands-on experience with CFD and heat transfer simulation tools such as STAR-CCM+
• Experience with CAD tools such as Teamcenter and UG-NX
• Strong engineering knowledge in heat transfer and fluid flow
• Understanding of calibrations and controls
• Excellent verbal and written communication skills
• Strong collaboration skills and ability to work effectively across functional teams

What Will Give You a Competitive Edge (Preferred Qualifications)

• Master's or PhD in Mechanical Engineering (Thermal Sciences emphasis) or Aerospace Engineering preferred
• Experience in thermal development or automotive system design and release, especially thermal-focused
• Advanced experience in propulsion cooling or airflow development
• Experience as a controls engineer
