Job Description

• Develop and execute CFD simulations for refrigerant leakage, gas dispersion, and ventilation analysis
• Model multiphase flows, multi-species transport, and transient flow behavior
• Perform fire and combustion simulations, including ignition, flame propagation, and heat release
• Analyze hazard scenarios such as confined space leakage, accumulation, and flammability limits
• Apply appropriate boundary conditions for leak sources, mass flow rates, and environmental conditions
• Conduct steady-state and transient simulations for leak evolution and fire scenarios
• Interpret results to identify risk zones, ignition probability, and mitigation strategies
• Support V&V activities, including comparison with test data and literature correlations
• Prepare technical reports highlighting assumptions, risks, and safety insights
• Collaborate with cross-functional teams on safety, compliance, and product design

• Bachelor’s / Master’s in Mechanical, Chemical, Aerospace Engineering, or related field
• 4–8 years of experience in CFD with focus on fluid flow and safety modeling

• Strong fundamentals in:
