Job Description

CFD Simulation Engineer – Conjugate Heat Transfer (CHT)

Bring complex thermal systems to life through simulation.

We’re looking for a hands-on CFD Simulation Engineer with deep experience in Conjugate Heat Transfer (CHT) to help us model, analyze, and optimize high-performance engineering systems. If you enjoy turning physics into insight, automating workflows, and collaborating across design and test teams, this role is built for you.

You’ll work with industry-leading tools like STAR-CCM+, ANSYS Fluent, and OpenFOAM , developing accurate and scalable CFD models that directly influence product design, validation, and performance.

What You’ll Do

Develop and run full-system CFD models focused on CHT and thermal-fluid behavior
Perform geometry cleanup, meshing, and surface preparation using ANSA and STAR-CCM+
Build, calibrate, and validate models using test data and reference benchmarks
Execute simulations in STAR-CCM+, Fluent, and OpenFOAM , balancing accuracy and computational efficiency
Conduct parametric studies, sensitivity analyses, and design optimization
Create automation and scripting tools (Python, Java, macros) to speed up model setup and post-processing
Partner with design, test, and systems teams to translate simulation results into actionable design guidance
Clearly document simulation methodologies, assumptions, and validation results

What We’re Looking For

3+ years of hands-on CFD experience , with a strong focus on CHT and thermal-fluid coupling

Strong proficiency in STAR-CCM+ ; working knowledge of ANSYS Fluent and OpenFOAM

Solid experience with ANSA for geometry preparation and meshing (CATIA exposure is a plus)

Strong understanding of heat transfer fundamentals —conduction, convection, and radiation

Experience with heat-transfer-driven CFD modeling , ideally within automotive or complex mechanical systems

Working knowledge of Python, Bash, or Java macros for simulation automation

Familiarity with HPC environments , parallel computing, and GPU acceleration (NVIDIA A100 / H100) is a bonus

Nice to Have

Experience with DOE, parametric studies, and optimization frameworks

Exposure to CAD tools such as CATIA or SolidWorks

Knowledge of post-processing and visualization tools (ParaView, Ensight, Tecplot)

Strong analytical thinking with the ability to clearly communicate technical insights

Education

Bachelor’s or Master’s degree in Mechanical Engineering, Aerospace Engineering, or a related field
