• Develop high‑voltage routing and busbar systems, ensuring compliance with creepage and clearance requirements
• Package and integrate HV and LV electrical components, considering EMC, ventilation, condensation, safety, serviceability, and manufacturing constraints
• Perform mechanical design of protective enclosures and support systems for electronic components and harnesses (metallic and plastic), accounting for mechanical loads and vibration
• Design protective enclosures to safeguard against environmental impacts and contamination
• Apply design‑for‑manufacturing and cost‑optimization principles
• Support electrical and system engineers in preparing schematics and formboard drawings
• Support interface selection (connectors, switches, indicators, etc.) to ensure system requirements are fulfilled
• Create technical drawings for customers and manufacturing
• Support product and documentation release in Teamcenter
• Participate in prototyping and validation of designed components

Requirements

• Bachelor’s or Master’s degree in Mechanical Engineering or a related field, or equivalent experience
• 3+ years of mechanical design experience, including exposure to cell integration, structural integration, power electronics, or high‑performance lithium‑ion batteries
• Experience with plastic parts and injection molding
• Experience with various mechanical joining methods
• Strong hands‑on CAD skills
• Excellent analytical skills, particularly in design for safety, production, and serviceability
• Experience working in international teams and with customers
• Excellent written and spoken English
• Experience from a start‑up environment is a strong plus
