You will be responsible for developing, executing, and optimizing CFD models to support thermal management, design validation, and performance improvement of complex engineering systems.

• Develop and execute CHT and thermal-fluid CFD simulations for full-system models.
• Perform geometry cleanup, meshing, and surface preparation using ANSA and STAR-CCM+.
• Build, calibrate, and validate CFD models using experimental or reference data.
• Run simulations in STAR-CCM+, Fluent, and OpenFOAM, ensuring model accuracy and computational efficiency.
• Conduct parametric, design optimization, and sensitivity studies.
• Develop automation and scripting tools (e.g., Python, Java, or macro scripting) to streamline model setup and post-processing workflows.
• Collaborate with design, test, and system integration teams to interpret results and provide actionable insights.
• Document methodologies, simulation plans, and validation results clearly and concisely.

• Bachelor’s or Master’s degree in Mechanical, Aerospace Engineering or related field.
• 3+ years of hands-on experience in CFD simulations, particularly CHT and thermal-fluid coupling.
• Familiarity with computational method for modeling heat transfer – radiation, conduction and convection. Experience in CFD modeling building focused on heat transfer mechanisms preferably automotive application.
• Experience with Python, Bash, or Java macros for CFD process automation.

• Proficiency in STAR-CCM+, working knowledge of ANSYS Fluent and OpenFOAM.
• Understanding HPC environments, parallel computing, and GPU acceleration (HPC clusters, NVIDIA A100/H100).
• Strong experience with ANSA for geometry preparation and mesh generation, working knowledge of CATIA.
• Experience with parametric studies, DOE, and optimization frameworks.
• Familiarity with CAD tools (CATIA, Solid Works) for model import/export.
• Knowledge of data visualization tools (Para View, Ensight or Tecplot).
• Strong analytical mindset and ability to communicate technical insights effectively.

• Envision the Future
• Communicate Honestly and Broadly
• Seek Technology and Business “First”
• Embrace Diversity and Take Risks

• Competitive Salary
• Comprehensive Benefit Package
• 401(k) with matching contributions
