Mission and Main Objective
- Develop the three-dimensional mechanical design of the equipment, ensuring that it can be manufactured and assembled.
- Efficiently manage the dissipation of heat generated by the electronics using advanced cooling systems.
- Ensure compliance with environmental protection, vibration, and mechanical safety regulations for the product.

Key Functions
- 3D Modelling and Drawings: Design the enclosure, support structures, ventilation ducts, and busbar mounting systems.




- Thermal Simulation (CFD): Perform computational fluid dynamics analyses to optimize heat sinks and cooling systems.
- Structural Analysis (FEA): Validate the mechanical strength of the chassis against transportation stresses, earthquakes, impacts (IK ratings), and vibrations.
- Material Selection: Determine the optimal materials (aluminium, steel, engineering plastics) by considering cost, weight, corrosion, and dielectric properties.
- Tolerance Management and DFMA: Apply design-for-manufacturing-and-assembly (DFMA) methodologies to ensure the equipment’s watertightness (IP ratings).

Profile RequirementsEducation: Bachelor’s degree in Mechanical Engineering. A master’s degree or specialization in Thermal Simulation or Product Development is highly desirable.
Experience: More than 8 years in mechanical design of capital goods, electrical cabinets, power electronics, or the automotive ind
