• Conduct thermal runaway, heat dissipation, and cooling system performance testing for battery packs and modules.
• Support high-voltage and environmental testing, including overcharge, vibration, and mechanical stress tests.
• Collect, process, and analyze thermal and electrical test data, identifying key trends and failure modes.
• Work closely with battery design, thermal, and systems engineering teams to optimize cooling strategies and heat dissipation.
• Ensure test lab safety by following high-voltage procedures and thermal safety best practices.
• Maintain organized documentation of test plans, results, and observations to support design improvements and certification efforts.

• As part of the ESPS organization, you will act as a Battery & Thermal Test Engineer supporting the validation and certification of advanced battery and thermal management systems for eVTOL aircraft.
• You will execute battery and thermal test protocols to evaluate performance, safety, and reliability.
• You will work with test engineers and technicians to ensure accurate test execution and data collection.
• You will support root cause analysis, investigating thermal and electrical test failures.
• You will help maintain and troubleshoot test setups, instrumentation, and high-voltage thermal control systems.
• You will work closely with certification teams to ensure compliance with aviation battery safety and thermal management standards.
• You will contribute to the continuous improvement of battery and thermal test methods, automation, and lab operations.

• B.S. in Mechanical Engineering, Electrical Engineering, Chemical Engineering, or a related field, with 2-5 years of experience in battery and thermal testing, preferably in the automotive, aerospace, or energy storage industries.
• Hands-on experience with battery test equipment, high-voltage systems, thermal sensors, and environmental chambers.
• Familiarity with thermal characterization methods, including heat flux measurements, IR thermography, and cooling system evaluations.
• Experience with test automation, data acquisition, and analysis tools (e.g., Python, MATLAB, LabVIEW).
• Basic understanding of battery systems, BMS, cooling technologies, and thermal safety testing.
• Ability to troubleshoot test setups, instrumentation, and data collection issues.
• Strong organizational and documentation skills, with attention to detail and accuracy.
• Ability to work independently while collaborating effectively with test engineers, technicians, and design teams.
• This role may require up to 25% travel for test site support.
