About the Job

Requirements

A bachelor's degree or higher in Mechanical Engineering, or equivalent experience.
Strong mechanical fundamentals and a first-principles problem-solving approach.
Proven ownership of product design from concept through validated hardware to scaled production, or equivalent depth.
Fluency in 3D computer-aided design, with CATIA V5 or 3DEXPERIENCE V6 strongly preferred.
Working knowledge of geometric dimensioning and tolerancing, tolerance analysis, and design for high-volume manufacturing, including injection molding, stamping, die casting, fastening, joining, and dispensing.
Ability to run or critically evaluate thermal, computational fluid dynamics, or structural analysis using ANSYS, StarCCM, COMSOL, or equivalent.
Comfort with printed circuit board assemblies, basic electrical fundamentals, and collaboration across electrical engineering and power electronics domains.

Responsibilities

Own electro-mechanical design of plastics, sheet metal, die castings, heat sinks and cold plates, insulation systems, magnetic components, high-voltage connectors, fasteners, busbars, and printed-circuit-board-assembly-adjacent structures.
Solve electronics packaging end to end, including thermal management, electrical isolation, sealing, interconnection, shock, vibration, and strain, electromagnetic interference, and radio-frequency interfaces.
Analyze designs using thermal and computational fluid dynamics analysis, structural finite element analysis, tolerance stacks, design for manufacturing, design for assembly, design for reliability, and design failure mode and effects analysis where appropriate.
Design custom magnetics and power interfaces, including inductors, transformers, filter chokes, and terminals, as mechanical products.
Partner with electrical, firmware, systems, manufacturing, compliance, and test teams so mechanical design choices support converter performance.
Drive prototypes through builds, fixture and test support, characterization, design verification, and root-cause analysis of failures.
Release designs for production by preparing drawing packages, manufacturing instructions, product lifecycle management and engineering change orders, deviations, bill-of-materials structure, and coordinating with suppliers and factories.
Develop designs for vehicles, residential and industrial energy products, and charging systems manufactured at scale.

Desired Qualifications

Direct experience in power electronics packaging, inverters, chargers, DC-DC converters, magnetics, busbars, or high-voltage semiconductor modules.
Multiphysics intuition across heat transfer, fluids, mechanics, materials, and preferably magnetics.
MATLAB or Python for data reduction, scripting, or reduced-order thermal models.
Product lifecycle management, change control, and bill-of-materials discipline in a fast-moving product environment.
Exposure to automotive, industrial, or residential reliability, safety, or environmental standards.
A hands-on laboratory approach, including instrumenting prototypes.

Job Description

<p>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.</p><p>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. </p>

Job Responsibilities

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

Job Requirements

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

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.
