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

What To Expect
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.

What You'll Do

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.

What You'll Bring

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
