• Analyse heat conduction, convection and, where applicable, radiation.
• Develop CFD models to evaluate airflow, cooling performance and temperature distribution.
• Use OpenFOAM for thermal and CFD simulations.
• Use Gmsh or equivalent open-source tools for geometry preparation and mesh generation.
• Define thermal boundary conditions, material properties, component power losses and simulation parameters.
• Evaluate component and PCB temperatures, thermal hotspots and cooling effectiveness.
• Develop Python-based automation and post-processing workflows.
• Assess mesh independence, convergence and numerical stability.
• Correlate simulation results with analytical calculations and available reference data.
• Document modelling assumptions, limitations, results and verification evidence.

Required Skills

• Strong fundamentals in heat transfer, thermodynamics and fluid mechanics.
• Practical experience in CFD and thermal simulation.
• Knowledge of conduction, natural/forced convection and radiation.
• Experience with OpenFOAM or equivalent CFD tools.
• Familiarity with Gmsh or other mesh-generation tools.
• Understanding of material properties, thermal boundary conditions and heat-source modelling.
• Python scripting for automation and simulation post-processing.
• Ability to interpret simulation results and assess numerical accuracy.

Preferred Qualifications :

• Bachelor's or Master's degree in Mechanical, Thermal, Aerospace or related Engineering.
• 5+ years of relevant experience in CFD, thermal engineering or electronics cooling.
• Experience with PCB thermal analysis, power electronics, semiconductor cooling or electronic enclosures.
