At Tesla Engineering Germany in Freiburg, our Power Electronics team is building the future of sustainable energy by developing the power converters at the heart of Tesla Energy’s storage and vehicle-charging products. As a Power Electronics Design Intern, you will take real ownership of converter hardware — from concept and simulation, through schematic and PCB design, to prototype bring-up and validation in the lab — working alongside experienced engineers using modern tools in a state-of-the-art environment.

• Take ownership of your own sub-project and drive it from concept through to a working prototype
• Simulate and model converter topologies (DC/DC, DC/AC) to evaluate performance, efficiency and design trade-offs
• Contribute to schematic capture and PCB layout, optimizing for parasitics, thermal performance, EMC and manufacturability
• Build, bring up and debug prototype boards in the lab using oscilloscopes, power analyzers and other bench equipment
• Define and run test plans to characterize converters and semiconductors, including high-voltage and insulation testing
• Collaborate with cross-functional teams (mechanical, PCB layout, firmware and test) as they design, validate and manufacture power converters
• Document designs, calculations and test results to support the path to high-volume manufacturing

• Currently pursuing a Bachelor’s or Master’s degree in Electrical Engineering, Power Electronics, Mechatronics or a related field
• Good understanding of switched power converter operating principles (DC/DC, DC/AC) and core power electronics fundamentals
• Hands-on experience with circuit / converter simulation tools (e.g. LTspice, PLECS, MATLAB/Simulink) and with schematic capture and PCB design (Altium Designer or Cadence preferred)
• Familiarity with analog and digital circuit design, including basic low-voltage control circuitry — auxiliary power supplies (buck/boost/flyback), sensor interfaces, gate drive and protection
• Some hands-on lab experience with basic EE tools (oscilloscope, power supplies, signal generators) and an eagerness to build and debug hardware
• A curious, self-starter mindset — eager to take ownership of a problem, see it through and learn quickly along the way
• Working knowledge of MATLAB and/or Python, communication protocols (CAN, SPI, I2C), and an understanding of magnetics, capacitors and power semiconductors (Si / SiC / GaN) are preferred
