Simulation Engineer (CFD & Multiphysics) – Automotive Domain
Position: Simulation Engineer – CFD & Multiphysics
Experience: 6–9 Years
Industry: Automotive / Electric Vehicles (EV) / Automotive R&D
Location: Bangalore
Employment Type: Full-Time
Job Summary
We are seeking an experienced Simulation Engineer specializing in Computational Fluid Dynamics (CFD) and Multiphysics Simulation to join our engineering team. The ideal candidate will possess strong expertise in CFD simulations for automotive applications, including thermal management, aerodynamics, under-hood airflow, HVAC, battery cooling systems, and electric propulsion systems.
