We are seeking an experienced High Voltage Battery Test Engineer to join our Hardware Testing team. In this role, you will collaborate with a passionate, multi-disciplinary team to develop and execute hardware, firmware, and software solutions for validating Tesla’s high-voltage (HV) battery products against internal and industry standards. 

You will play a critical role in identifying reliability risks, shaping product design, and ensuring performance from early concept development through production launch and beyond. The ideal candidate is hands-on, thrives in a fast-paced environment, and has a strong problem-solving mindset with a track record of technical excellence and collaboration. 

• Lead component- and pack-level validation testing under realistic and accelerated dynamic and environmental conditions, including structural, vibration, thermal, and electrical testing
• Design, build, and automate test infrastructure for battery system and component testing
• Investigate test and field failures to drive product development and improve validation processes
• Collaborate cross-functionally with Design Engineers, Reliability Scientists, Material Scientists, Quality, and Service teams to identify failure modes and define robust validation plans
• Develop and execute design validation plans (DVPs) and test methods to ensure compliance with performance requirements
• Lead high-voltage battery testing programs, mentoring engineers and influencing critical product decisions
• Utilize data acquisition, instrumentation, and automation for precise testing and analysis
• Present findings and recommendations to cross-functional teams and leadership

• Engineering Degree in Mechanical Engineering, Mechatronics, Electrical Engineering or equivalent with 3+ years of work experience
• Strong knowledge in data acquisition, solid mechanics, material science, heat transfer, failure analysis, and digital electronics
• Experience with object-oriented programming and scripting (Python, C++, etc.) for hardware control and data analysis
• Proficiency in 3D CAD software for designing test automation systems, mechanical structures, or mechatronic systems
• Familiarity with high-voltage systems and electrical test equipment
• Experience leading technical projects, coordinating with multiple teams, and balancing competing priorities
• Passion for hands-on problem-solving and first-principles thinking
