Motorsports CFD Surface Design Engineer

About the role

As a CFD Surface Design Engineer at GM Motorsports, you will develop, maintain, and automate complex CAD assemblies that form the foundation of our high-fidelity aerodynamic simulations. Leveraging advanced CAD and scripting tools, you will ensure robust, parametric, and simulation-ready geometry to support rapid design iteration within GM's Aerodynamics Group. In this role, you will work closely with CFD engineers to enable efficient mesh generation, reduce model preparation time, and improve consistency across full-vehicle and subsystem CFD studies. By integrating automated processes and scalable design practices, you will enhance the reliability and throughput of simulation-driven development. Collaboration is central to success in this position. You will partner with cross-functional teams across GM Motorsports and key external partners to align CAD strategies to advance CFD simulations, wind tunnel testing, and on-track implementation. Your contributions will directly impact the speed and accuracy of design decisions, helping translate design ideas into high fidelity CAD to increase vehicle performance in a fast-paced racing environment.

Responsibilities

• Develop and maintain clean, simulation-ready CAD geometry for use in CFD workflows across multiple platforms
• Build and refine high-quality surface models with appropriate continuity to support accurate aerodynamic analysis
• Organize and manage CAD assemblies with clear structure, naming conventions, and version control for efficient CFD use
• Incorporate parametric design and automation features to enable rapid updates, configuration changes, and repeatable CFD workflows
• Reconstruct and refine legacy, imported or scanned/point cloud geometry to meet internal CFD and aerodynamic standards
• Optimize models for usability, ensuring they are easy to modify, update, and reuse across simulation studies
• Identify and resolve geometry issues that negatively impact mesh quality, solver stability, or convergence
• Collaborate with cross-functional teams to translate design intent into efficient, simulation-ready models and support iterative development cycles
• What You'll Need (Required Qualifications):
• Bachelor's Degree in Engineering, Physics, or related subjects
