Lead Test Engineer

The Role

We are looking for a Lead Test Engineer to build and lead Moment Energy’s testing and validation capabilities. This role is responsible for defining and executing the testing strategy that ensures the safety, reliability, and performance of our battery energy storage systems (BESS).

• Own and lead Moment Energy’s testing and validation strategy across R&D, product development, and certification.
• Develop and maintain comprehensive test frameworks covering component, subsystem, rack, and full BESS-level validation.
• Establish testing standards, methodologies, and best practices across the engineering organization.
• Mentor and guide Test Engineers, providing technical leadership and support on complex testing activities.
• Collaborate closely with engineering teams to define validation plans for new products, features, and design changes.

• Design, build, and scale advanced test infrastructure for battery modules, racks, and full BESS systems.
• Lead the development of automated testing systems, data acquisition infrastructure, and long‑duration reliability testing capabilities.
• Oversee lab safety procedures and ensure safe operation of high‑voltage testing environments.
• Maintain and improve lab equipment, including battery cyclers, DAQ systems, power supplies, and instrumentation.

• Design and execute complex test plans for product validation, certification, R&D investigations, and lifecycle testing.
• Build and oversee advanced test setups involving high‑voltage DC and AC systems (up to 1000 VDC, 600 VAC).
• Operate battery cyclers to conduct testing on cells, modules, racks, and full BESS units.
• Develop custom test fixtures and experimental setups to evaluate new concepts and investigate failure modes.
• Support certification and compliance testing, including pre‑compliance testing and coordination with certified test labs.

• Develop automated test scripts and tools to streamline testing and data collection.
• Analyze large test datasets using Python or similar tools to identify performance trends, reliability issues, and failure mechanisms.
• Produce clear reports and presentations summarizing results and engineering recommendations.
• Work with cross‑functional teams to translate test results into actionable design improvements.

• Bachelor’s or Master’s degree in Electrical Engineering, Mechatronics, or a related engineering discipline.
• 6+ years of experience in hardware testing, validation, or verification roles.
• Strong experience designing and executing complex engineering test plans and validation programs.
• Demonstrated experience working safely with high‑voltage DC and AC systems.
• Deep experience building electro‑mechanical test setups, wiring instrumentation, and configuring test equipment.
• Experience with data acquisition systems (DAQ), instrumentation, and test automation.
• Strong data analysis capabilities using tools such as Python, MATLAB, or similar environments.
• Proven ability to lead technical initiatives and mentor engineers in a collaborative environment.
• Excellent problem‑solving skills and ability to investigate complex system failures.
• Previous experience in a high‑growth fast‑paced environment is highly desired.

• Experience testing lithium‑ion battery systems, battery modules, or battery energy storage systems.
• Familiarity with battery cyclers and battery management systems (BMS).
• Knowledge of battery and energy storage safety standards such as UL1973, UL9540, and related compliance frameworks.
• Experience with industrial communication protocols such as CAN, Modbus, or SCPI.
• Experience testing power electronics, inverters, and grid‑connected energy systems.

• Today, we’re delivering 5x the energy density and have all the certifications needed to ship energy independence to the world.
• Be part of a mission‑driven company focused on creating sustainable energy solutions and making a positive impact on the world.
• Collaborate closely with passionate co‑founders and a team committed to innovation and excellence.
• Contribute to building and scaling a…
