Job purpose The role of CFD Simulation Engineer Vehicle Cooling Performance will support vehicle cooling performance development through high-fidelity computational fluid dynamics (CFD) analysis. The role focuses on thermal management systems, and cooling system optimization for engines, power electronics, batteries, and HVAC systems. The role will collaborate closely with vehicle engineering, thermal, powertrain, and CAE teams to ensure vehicles meet performance, efficiency, and reliability targets while supporting concept, development, and validation phases. Key duties and responsibilities CFD Simulation & Thermal Analysis: Develop, run, and maintain CFD models to predict airflow, heat transfer, pressure losses and cooling performance across vehicle systems. Perform simulations for engine cooling, battery thermal management, HVAC airflow, and under bonnet aerodynamics. Support design optimisation of radiators, heat exchangers, ducts, fans, and cooling components. Conduct sensitivity studies and trade-off analyses to guide component and system-level decisions. Model Validation & Correlation: Correlate CFD predictions with experimental data from wind tunnel, thermal rig, and on-vehicle testing. Validate models and refine simulation setups to improve fidelity and predictive capability. Provide actionable recommendations based on simulation insight to improve thermal performance. Tools, Methods & Continuous Improvement: Develop and improve CFD workflows, meshing strategies, and post-processing methods. Apply scripting and automation to enhance simulation efficiency. Contribute to best practices in vehicle cooling CAE and CFD simulation. Stay current with emerging CFD methods, solvers, and thermal management techniques. Experience and qualifications Required Qualifications & Experience Degree in Mechanical, Automotive, Aerospace Engineering, or related discipline. Experience in CFD simulation for vehicle cooling, thermal management, or under bonnet airflow. Strong understanding of heat transfer, fluid mechanics, and thermal system behaviour. Proven ability to correlate simulation results with test data. Experience supporting vehicle development programmes. Technical Skills CFD solvers (e.g., STAR-CCM, ANSYS Fluent, OpenFOAM). Meshing and pre-processing tools. Post-processing and data analysis (e.g., MATLAB, Python). Understanding of HVAC, engine, battery, and power electronics cooling systems. Experience in using HIGH PERFORMANCE PRODUCT environments for complex simulations. Desirable Attributes Experience with EV thermal management, including battery and inverter cooling. Exposure to conjugate heat transfer (CHT) or multi-physics simulations. Background in motorsport, high-performance, or luxury vehicle thermal systems. Strong analytical, problem-solving, and communication skills. Proactive, detail-oriented, and hands-on approach to simulation challenges. Additional requirements The requirement to work on-site 3 days a week as minimal. Flexibility on start and finish times due to events and different locations is required.
