(Senior) Mechanical Design Engineer – Power Electronics (m/f/d)
First seen by Alion on Nov 3, 2026.
### What to Expect
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. Join our team to collaborate across different engineering areas, solve meaningful challenges creatively and transfer concepts from initial design, through prototyping and testing into real-world solutions.This is an opportunity to own key projects, use modern tools, and work in state-of-the-art facilities to create technologies that shape how energy systems evolve. You get to work on advancing power electronics used for Tesla products globally, thereby directly contributing to the acceleration of the world's transition to sustainable energy.
### What You’ll Do
- Own electro-mechanical design of plastics, sheet metal, die castings, heat sinks / cold plates, insulation systems, magnetic components, HV connectors, fasteners, busbars, and PCBA-adjacent structures
- Solve electronics packaging end-to-end: thermal management, electrical isolation, sealing, interconnection, shock/vibration/strain, EMI, and RF interfaces
- Analyze before you cut metal: thermal / CFD, structural FEA, tolerance stacks, DFM / DFA / DFR; DFMEA where it matters
- Design custom magnetics and power interfaces (inductors, transformers, filter chokes, terminals) as first-class mechanical products — not afterthoughts
- Partner tightly with electrical, firmware, systems, manufacturing, compliance, and test so mechanical choices enable — not fight — converter performance
- Drive prototypes into reality: builds, fixture/test support, characterization, design verification, root-cause on failures
- Release for production: drawing packages, manufacturing instructions, PLM / ECOs / deviations / BOM structure, supplier and factory collaboration
- Ship globally: designs that land in vehicles, residential/industrial energy products, and charging systems manufactured at scale
### What You’ll Bring
- Bachelor degree or higher in Mechanical Engineering or equivalent experience;
- Strong mechanical fundamentals and a first-principles problem-solving style
- Proven product design ownership (from concept to validated hardware to scaled production, or equivalent depth)
- Fluency in 3D CAD (CATIA V5 / 3DEXPERIENCE V6 strongly preferred)
- Working knowledge of GD&T, tolerance analysis, and design for high-volume manufacturing (injection molding, stamping, die casting, fastening, joining, dispensing)
- Ability to run or critically consume thermal / CFD / structural analysis (ANSYS, StarCCM, COMSOL, or equivalent)
- Comfort with PCBAs, basic electrical fundamentals, and collaborating across EE / PE domains Highly valued:
- Direct experience in power electronics packaging, inverters, chargers, DC-DC, magnetics, busbars, or HV semiconductor modules
- Multiphysics intuition: heat transfer + fluids + mechanics + 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
- Exposure to automotive, industrial, or residential reliability / safety / environmental standards
- Hands-on lab instinct — you would rather instrument a prototype than argue from a slide
