Engineering Test Technician, Energy Storage

As an early member of a new engineering technician team, you will play a key role in building, setting up, and running tests to support the development of a new product at Redwood Materials. You’ll work hands-on across mechanical, electrical, and basic software tools to help validate product performance and reliability. You will support all phases of the hardware development lifecycle from early design validation and long-term reliability testing to final process validation by assembling test setups, operating equipment safely, capturing data, and troubleshooting issues as they arise. This role requires a proactive, can-do attitude with careful attention to detail and a strong safety mindset.

Hours: Full-time, Days

Responsibilities Will Include:

• Build, set up, and execute validation tests for a new electromechanical product

• Partner with cross-functional teams (design, reliability, and abuse engineers) to support FMEAs and test plan execution

• Assemble, install, and maintain test infrastructure such as fixtures, sensors, actuators, chambers, and power supplies

• Operate test equipment, follow procedures, and ensure safe handling of high-voltage systems and lab hardware

• Collect, organize, and document test data, observations, and results clearly and consistently

• Perform basic failure triage and support failure analysis through teardown, inspections, and root-cause investigations

• Troubleshoot test setups and hardware issues; escalate and collaborate to resolve blockers quickly

• Support test automation and data logging tools (e.g., running scripts, validating outputs, contributing small updates as needed)

• Support New Product Introduction (NPI) line operations by assisting with product assembly, build readiness, and day-to-day troubleshooting. Create, update, and maintain build documentation, including work instructions, assembly procedures, and change logs to ensure accurate and repeatable processes

• Support with the management of lab inventory, organization, and power infrastructure. Assembly and validation of high-voltage harnesses and electrical sub-systems, including wiring, terminations, and integration while ensuring full compliance with electrical safety requirements and site policies

Desired Qualifications:

• Associate degree, technical certification, or equivalent hands-on experience in mechanical, electrical, mechatronics, or related fields

• 3+ years of experience in a lab, manufacturing, or test environment (technician, engineering tech, or similar role)

• Experience working with or around high-voltage systems (400–2000VDC and 480–800VAC) and strong safety discipline (LOTO, PPE, safe work practices)

• Strong hands-on skills with mechanical assembly, wiring, sensors, instrumentation, and lab equipment

• Comfortable following test procedures, maintaining detailed documentation, and producing clear test summaries

• Familiarity with basic scripting or automation tools (Python a plus) and the ability to learn new tools quickly

• Strong communication and teamwork skills; able to work effectively with engineers and stakeholders across levels

• A get-it-done attitude—willing to jump in, own tasks end-to-end, and do what’s needed to support the team

Physical Requirements:

• Ability to perform essential physical tasks such as standing, walking, bending, stooping, climbing, lifting (up to 25 lbs), typing, and performing repetitive motions

• Manual dexterity to work with small components under a microscope for extended periods, including precision soldering and handling heavy copper assemblies

Working Conditions:

• Ability to work in working conditions which may include exposure to noise, dust, chemicals, and temperature extremes, while protected by PPE, for extended periods of time

• Occasional travel required and flexibility to work weekends, nights, or on call as needed

The position is full-time. Compensation will be commensurate with experience.
