CFD Simulation Engineer automotive in Raymond, OH

A global automotive company in Raymond, Ohio is seeking a highly skilled CFD Simulation Engineer with strong expertise in Conjugate Heat Transfer (CHT) analysis. This role focuses on developing and executing high-fidelity CFD simulations to support thermal management, design validation, and performance optimization of complex automotive engineering systems.

The ideal candidate will have hands-on experience with STAR-CCM+, along with working knowledge of ANSYS Fluent and OpenFOAM, strong pre-processing skills using ANSA, and experience developing automation and scripting tools to accelerate simulation workflows. This position requires a minimum of four days onsite per week.

• Develop and execute CHT and thermal-fluid CFD simulations for full-system and component-level models
• Perform geometry cleanup, surface preparation, and mesh generation using ANSA and STAR-CCM+
• Build, calibrate, and validate CFD models using experimental data or benchmark references
• Execute simulations using STAR-CCM+, ANSYS Fluent, and OpenFOAM, ensuring accuracy and computational efficiency
• Conduct parametric studies, sensitivity analyses, and design optimization to support engineering decisions
• Develop and maintain automation and scripting tools (Python, Java, macros) to streamline model setup, execution, and post-processing
• Collaborate closely with design, test, and systems engineering teams to interpret results and provide actionable recommendations
• Document simulation methodologies, assumptions, and validation results clearly and concisely

• Bachelor’s or Master’s degree in Mechanical Engineering, Aerospace Engineering, or a related field
• 3+ years of hands-on experience in CFD simulations, with a focus on CHT and thermal-fluid coupling
• Proficiency in STAR-CCM+; working knowledge of ANSYS Fluent and OpenFOAM preferred
• Strong experience using ANSA for geometry preparation and mesh generation; working knowledge of CATIA preferred
• Solid understanding of heat transfer mechanisms, including conduction, convection, and radiation
• Experience modeling thermal systems, preferably in automotive or transportation applications
• Experience with Python, Bash, or Java for CFD process automation
• Familiarity with HPC environments, parallel computing, and GPU acceleration (e.g., NVIDIA A100/H100) is a plus

• Experience with parametric studies, DOE, and optimization frameworks
• Familiarity with CAD tools such as CATIA or Solid Works for model import/export
• Experience with data visualization tools such as Para View, Ensight, or Tecplot
• Strong analytical skills with the ability to communicate complex technical concepts clearly and effectively
