About the Job

Requirements

A bachelor's degree or higher in Mechanical Engineering, or equivalent experience.
Strong mechanical fundamentals and a physics-based, first-principles approach to structural and thermal problems.
Proven product design ownership from concept to scaled production.
For the lead track, 7+ years of relevant product design experience, including 2+ years of design leadership.
Fluency in CATIA V5 / 3DEXPERIENCE, geometric dimensioning and tolerancing (GD&T), tolerance analysis, and design for high-volume processes including molding, stamping, die casting, fastening, joining, and dispensing.
Ability to run or critically review thermal, computational fluid dynamics (CFD), and structural analysis, plus working knowledge of power electronics components including PCBAs, MOSFETs, inductors, and transformers.
Clear written and verbal communication in English.

Responsibilities

Own the electromechanical design of injection-molded plastics, sheet metal, high-pressure die castings, heat sinks and cold plates, insulation systems, magnetics, high- and low-voltage interconnects, busbars, and PCBA-adjacent structures.
Solve electronics packaging end-to-end, including thermal management, high-voltage insulation (creepage and clearance), IP67+ sealing, electromagnetic interference (EMI), shock and vibration, and long-term environmental reliability.
On the 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.
Perform thermal and CFD analysis, structural finite element analysis (FEA), tolerance stack analysis, design for manufacturing (DFM), design for assembly (DFA), design for reliability (DFR), and design failure mode and effects analysis (DFMEA) as appropriate.
Design custom magnetics and power interfaces, including inductors, transformers, chokes, and terminals, as first-class mechanical products.
Partner with electrical, systems, reliability, manufacturing, supply chain, and compliance teams, and design to UL, IEC, and GB standards through certification.
Drive prototypes through builds, test support, characterization, design verification, and root-cause analysis of failures.
Release products for production in CATIA 3DEXPERIENCE, including 3D models, 2D drawings with GD&T, PLM / ECOs / BOMs, and supplier collaboration for automated manufacturing at thousands of units per week.

Desired Qualifications

A master's degree is preferred for senior, staff, or lead level.
A portfolio demonstrating product design ownership from concept to scaled production is preferred.
Direct experience in power electronics packaging, including inverters, chargers, DC-DC converters, magnetics, busbars, or high-voltage semiconductor modules.
Experience designing to certification standards (UL, IEC, GB) and obtaining certificates.
Multiphysics intuition across heat transfer, fluids, mechanics, and materials; magnetics is a strong plus.
MATLAB or Python for data reduction, scripting, or reduced-order thermal models.
PLM, change control, and BOM discipline in a fast-moving product environment.
Hands-on lab instinct, including instrumenting prototypes.

Job Description

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.

Job Responsibilities

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

About the Company

Tesla

Makes electric cars, robotaxis and grid batteries

Tesla makes electric cars and batteries that store power for homes and utilities, and it develops self-driving software and humanoid robots. In 2023, its Model Y became the first electric vehicle to rank as the world's best-selling car. Buyers order the Model 3 sedan, Model Y SUV, or Cybertruck pickup directly from Tesla instead of through dealers, and they charge on its Supercharger fast-charging network. It also sells Megapack and Powerwall batteries, runs a robotaxi service, and charges drivers a monthly fee for self-driving software that still needs their supervision. Tesla was founded in 2003, with Elon Musk as its lead early investor and a recognized co-founder, and it is based in Austin, Texas.
