Lead Mechanical Design Engineer, Power Electronics (m/f/d)

Tesla Germany GmbH; Freiburg im Breisgau; On-site; EUR 90,000 - 130,000; Full time

Job summary

Tesla Engineering Germany in Freiburg is seeking an experienced Mechanical Engineer to own cradle-to-grave design of electromechanical systems for power electronics used in energy storage and vehicle charging. You will lead a product line, mentor engineers, and ensure designs meet reliability and certification standards.

Key qualifications include 7+ years in product design with leadership, strong CATIA V5/3DEXPERIENCE proficiency, and experience with high-volume processes.

Qualifications

• Bachelor's degree in Mechanical Engineering or equivalent experience.
• Master's degree preferred for senior/ staff/ lead level.

Responsibilities

• Own the electromechanical design of injection-molded plastics, sheet metal, die castings, heat sinks, insulation systems, magnetics, HV/LV interconnects, busbars, and PCBA-adjacent structures.
• Solve electronics packaging end-to-end: thermal management, high-voltage insulation, IP67+ sealing, EMI, shock/vibration, environmental reliability.
• Lead track: technical owner of a product line; mentor 3–4+ engineers; lead design reviews; enforce technical rigor and schedules.
• Analyze before you cut metal: thermal/CFD, structural analysis, tolerance stacks, DFM/ DFA/ DFR, DFMEA.
• Design custom magnetics and power interfaces (inductors, transformers, chokes, terminals) as first-class mechanical products.
• Partner with electrical, systems, reliability, manufacturing, supply chain, and compliance; design to UL/ IEC/ GB standards to certification.
• Drive prototypes into production: builds, test support, characterization, design verification, root-cause analysis.
• Release for production in CATIA 3DEXPERIENCE: 3D models, 2D drawings with GD&T, PLM/ECOs/BOMs; collaborate with suppliers for high-volume manufacturing.

Job description

What to Expect

Please not: roles are open at multiple seniority levels for demonstrated excellence.At Tesla Engineering Germany in Freiburg, we're building the future of sustainable energy by developing innovative power electronics for energy storage and vehicle charging systems. You will own the cradle-to-grave mechanical design of tightly integrated, high-volume electromechanical systems, from first concept through prototyping and validation to mass production. You'll work closely with Electrical, Product, Reliability, Manufacturing, and Supply Chain teams. This is an opportunity to own key projects, use modern tools, and work in state-of-the-art facilities on power electronics that ship in Tesla products worldwide. Your work contributes directly to the world's transition to sustainable energy. At the lead level, you will also set technical direction and guide a small team of mechanical engineers.

What You’ll Do

• Own the electromechanical design of injection-molded plastics, sheet metal, high-pressure die castings, heat sinks / cold plates, insulation systems, magnetics, HV/LV interconnects, busbars, and PCBA-adjacent structures
• Solve electronics packaging end-to-end: thermal management, high-voltage insulation (creepage/clearance), IP67+ sealing, EMI, shock/vibration, and long-term environmental reliability
• Lead track: Serve as technical owner of a product line, mentor 3–4+ engineers, lead and approve design reviews, and enforce technical rigor and schedule discipline
• Analyze before you cut metal: thermal / CFD, structural FEA, tolerance stacks, DFM / DFA / DFR, and DFMEA where it matters
• Design custom magnetics and power interfaces (inductors, transformers, chokes, terminals) as first-class mechanical products, not afterthoughts
• Partner with electrical, systems, reliability, manufacturing, supply chain, and compliance teams, and design against UL / IEC / GB standards through to certification
• Drive prototypes into reality: builds, test support, characterization, design verification, and root-cause analysis of failures
• Release for production in CATIA 3DEXPERIENCE: 3D models, 2D drawings with GD&T, PLM / ECOs / BOMs, and supplier collaboration for automated manufacturing at thousands of units per week

What You’ll Bring

• Bachelor's degree or higher in Mechanical Engineering, or equivalent experience; Master’s degree preferred for senior/ staff/ lead level
• Strong mechanical fundamentals and a physics-based, first-principles approach to structural and thermal problems
• Proven product design ownership from concept to scaled production (portfolio preferred)
• Lead track: 7+ years of relevant product design experience, including 2+ years of design leadership
• Fluency in CATIA V5 / 3DEXPERIENCE, GD&T, tolerance analysis, and design for high-volume processes (molding, stamping, die casting, fastening, joining, dispensing)
• Ability to run, or critically review, thermal / CFD / structural analysis, plus working knowledge of power electronics components (PCBAs, MOSFETs, inductors, transformers)
• Detail-oriented, with clear written and verbal communication in English and the ability to thrive in a fast-paced environment Highly valued:
• Direct experience in power electronics packaging: inverters, chargers, DC-DC, magnetics, busbars, or HV semiconductor modules
• Experience designing against certification standards (UL, IEC, GB) and obtaining certificates
• Multiphysics intuition: heat transfer, fluids, mechanics, and materials (magnetics a strong plus)
• MATLAB / Python for data reduction, scripting, or reduced-order thermal models
• PLM / change control / BOM discipline in a fast-moving product environment
• Hands-on lab instinct: you would rather instrument a prototype than argue from a slide
