Role Overview
The AeroX & Climatic Comfort Engineer contributes to project and tender development by applying engineering processes and domain guidelines within the areas of internal aerodynamics, thermal behaviour, HVAC performance, and climatic comfort .
The role focuses primarily on thermo‐fluid dynamic simulations and comfort assessments , using tools such as STAR‐CCM+ and Therm to evaluate airflow distribution, thermal loads, ventilation efficiency, and overall passenger and driver comfort.
The engineer also performs experimental activities, both on mock‐ups (air duct networks, HVAC units,



environmental chambers) and on trains , to assess climatic performance during preliminary and final validation.
The position contributes to advanced methods development, R&D; initiatives, and cross‐disciplinary innovation activities.
