Engineering Test Technician, Energy Storage

About Redwood Materials

Redwood is localizing a global battery supply chain that seamlessly integrates recovery, reuse, and recycling—keeping critical minerals in circulation and driving the energy transition. Founded in 2017, we’re delivering low-cost and large-scale energy storage and producing battery materials in the U.S. for the first time, all from batteries we already have.

Essential Duties

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.

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; elevate 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 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 (400–2000 VDC and 480–800 VAC) 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 the essential job functions consistently safely and successfully with the ADA, FMLA and other federal, state and local standards, including meeting qualitative and/or quantitative productivity standards.
• Ability to maintain regular, punctual attendance consistent with the ADA, FMLA and other federal, state, and local standards.
• Ability to work with small components under a microscope for extended periods.
• Manual dexterity for precision soldering and handling heavy copper assemblies.
• Occasional lifting of up to 25 lbs.
