Thermal Hydraulics Engineer

About the role

We are seeking a skilled CFD Analyst / Thermal-Fluid Engineer to perform high-fidelity thermal-fluid simulations supporting nuclear and energy-related applications.

Responsibilities

• Develop and execute CFD models for thermal-fluid analysis.
• Perform simulations involving conjugate heat transfer, turbulence modeling, and single- or multi-phase flows.
• Apply sound numerical methods to ensure solution accuracy, stability, and convergence.
• Conduct mesh generation, sensitivity studies, and model validation against experimental or analytical data.
• Collaborate with system analysts, designers, and experimental teams to support integrated thermal-hydraulic evaluations.
• Document modeling assumptions, methods, and results in clear technical reports.

Qualifications

• MSc in Nuclear Engineering, Mechanical Engineering, or a related field.
• 5+ years of hands-on CFD experience applied to thermal-fluid problems.
• Demonstrated expertise with one or more CFD platforms (STAR-CCM+, COMSOL, Altair, Nek5000, or OpenFOAM).
• Strong background in numerical methods for fluid flow and heat transfer.
• Ability to independently plan and execute complex CFD analyses.

Preferred Qualifications

• Experience with nuclear-related CFD applications (e.g., reactor components, experimental test sections).
• Experience coupling CFD with system codes or structural/thermal solvers.
• Experience working in regulated or high-quality engineering environment.
• Experience on experimental thermal hydraulics is a plus.
