  • Design and build test fixtures and experimental setups for electrical, thermal, and mechanical testing.
  • Support process trial experiments to improve system performance and quality.
  • Collect, process, and analyze test data using engineering tools (e.g., Python, MATLAB, Excel, or similar).
  • Assist in root cause investigations using structured problem-solving methods such as 8D.
  • Help with BMS integration into test setups, including wiring, communication, and instrumentation.
  • Assist with system-level engineering activities such as requirements definition, DFMEA, and validation plans.
  • Work with cross-functional teams (mechanical, electrical, systems, manufacturing, and test engineering) to support development activities.
  • Document results and present findings to the engineering teams.

Required Skills

  • Currently pursuing a BS or MS in Electrical Engineering, Mechanical Engineering, Chemical Engineering, or related field
  • Strong interest in battery systems, energy storage, or electrified systems
