Mechanical Engineer for Power Electronics (m/f/d)

We are seeking a skilled, detail-oriented mechanical engineer to support the design and development of mechanical systems for high-power electronic converters. The role involves creating robust, thermally efficient mechanical designs, including enclosures, heat sinks and support structures, while ensuring compliance with mechanical, thermal and environmental requirements. The engineer will collaborate closely with cross‑functional teams to assist with prototype development, testing, and product integration. Other responsibilities include generating detailed CAD models, technical drawings, and manufacturing and validation documentation. This is an exciting opportunity to contribute to the development of innovative power electronic systems for use in renewable energy, electric mobility, and industrial applications.

Your Responsibilities

• Design 3D CAD models and 2D engineering drawings for power converter enclosures, heat sinks, busbars and support structures
• Develop and optimise thermal management solutions, including heatsink selection, airflow design and interface materials
• Perform thermal and structural simulations using tools such as ANSYS, SolidWorks Simulation or COMSOL
• Ensure that mechanical designs meet safety, IP rating, vibration and EMI shielding requirements
• Select appropriate materials and manufacturing processes to produce cost‑effective, high‑performance components
• Coordinate with suppliers, fabrication shops and internal teams for prototyping and small-batch production
• Support the assembly and validation of mechanical subsystems, including fit checks, thermal measurements and stress testing
• Document design changes, test results and engineering justifications in accordance with internal standards

Your Qualifications & Skills

• Degree in Mechanical Engineering or a related field
• Previous experience in mechanical design, preferably in the context of power electronics, electrical enclosures, or thermal systems
• Proficiency in CAD tools such as SolidWorks, Creo, or Autodesk Inventor
• Familiarity with thermal simulation and structural FEA tools (e.g., ANSYS, COMSOL)
• Understanding of thermal management techniques for electronics (convection, conduction, forced air, liquid cooling)
• Experience with manufacturing methods such as sheet metal fabrication, CNC machining, casting, and 3D printing
• Ability to interpret engineering drawings, tolerances, and standards (IEC, UL, IP ratings)
• Strong communication and collaboration skills; capable of working in a cross‑functional R&D team
• Excellent written and verbal communication skills in English, German is a plus

OUR COMMITMENT

• Innovative work environment in a young, dynamic team
• High‑tech projects in the future‑proof sector of e‑mobility
• Opportunities for advancement in a growing company
• A wide range of further training opportunities
• Attractive bonus system and performance-related pay
• Additional company benefits
