High-Voltage Distribution Test Internship, Powertrain Engineering Europe (m/w/d)

Berlin, Be May 15, 2026 Internship Tesla Custom Ats

The High-Voltage Distribution Hardware team is seeking a highly motivated intern to perform high-voltage tests. You will focus on hands-on high-voltage distribution hardware testing including setup, operation, and analysis of high-voltage reliability tests for battery systems and distribution components. You will work closely with senior engineers to execute complex tests, build fixtures, and analyze data in a fast-paced environment. At Tesla, scope and complexity of your assignments are limited by your aptitude, not seniority or title. 

  • Perform design, setup, and execution of high-voltage reliability tests, including environmental simulations (e.g., thermal cycling, vibration, and humidity testing) on battery packs and distribution hardware according to Standard Operating Procedures (SOPs).
  • Operate test equipment such as high-voltage power supplies, oscilloscopes, multimeters, and data acquisition systems.
  • Perform hands-on assembly and disassembly of test fixtures, prototypes, and hardware components, ensuring compliance with safety protocols for high-voltage environments.
  • Analyze test data using tools like MATLAB, Python, or Excel to identify failure modes, performance trends, and reliability metrics.
  • Collaborate with cross-functional teams to troubleshoot issues and iterate on test procedures.
  • Design and build mechanical and electrical test fixtures for High-voltage system and component testing.
  • Collaborate with test technicians to achieve test objectives.
  • Contribute to organizational tasks & responsibilities like creation & maintenance of procedures, SOPs, standards, equipment, inspections, lab commissioning, facilities, maintenance and staff trainings.
  • Acquire knowledge about relevant industry standards, testing guidelines, and norms.
  • Tasks require working with high-voltage (live batteries) and other hazardous energy using mandated PPE and procedures and to set up and perform tests in person and in lab environments.
  • Other tasks as required. 
  • Pursuing a degree in a relevant field (Mechanical, Electrical, Automotive, Chemical Engineering, Mechatronics, Physics, or similar).
  • Strong understanding of electrical circuits, mechanical systems, and high-voltage principles.
  • Keen interest in practical, lab-based work; prior experience in hardware testing, prototyping, or reliability engineering through coursework, projects, or previous internships.
  • Strong problem-solving abilities, attention to detail, and a proactive mindset.
  • Fluency in English; German is a plus.
  • Exceptional organization and communication skills (both written and verbal).
  • Ability to work independently in a safely critical environment

Additional Preferred Skills

  • Familiarity with testing equipment (e.g., oscilloscopes, power analyzers) is a plus.
  • Project management experience or foundations are a plus
