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 2019, 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.
Engineering Technician – Redwood Energy
Essential Duties:
We are seeking a skilled Engineering Technician with expertise in soldering and printed circuit board assembly (PCBA) rework to join our team. As an early member of a new engineering team, you will play a key role in supporting Hardware Engineering for Energy Products at Redwood Materials. The ideal candidate will have hands-on expertise working with high-voltage and high-current components, performing precision soldering, rework, and modifications on power converter and inverter boards, as well as supporting prototype builds and engineering evaluations. This role requires strong knowledge of high-voltage safety practices and is integral to ensuring quality and reliability in our power electronic products.

DESIRED QUALIFICATIONS:

• Associate’s degree in Electronics Technology or equivalent experience preferred
• 2+ years of electronics assembly and soldering experience, ideally in power electronics, automotive, renewable energy, or related industries
• Demonstrated experience working safely with high-voltage systems and compliance with electrical safety protocols
• Familiarity with high-voltage PCB layouts, creepage/clearance rules, and conformal coating rework a plus
• Proficiency in fine-pitch SMD soldering and heavy copper through-hole component rework
• Ability to read schematics and assembly drawings
• Hands-on experience with soldering irons, hot air rework stations, preheaters, and microscopes
• A get-it-done attitude; no job is too big or too small

PHYSICAL REQUIREMENTS:

• Ability to perform the essential job functions consistent 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

• Perform precision soldering and desoldering of power electronics components, including through-hole, high-current bus bars, and fine-pitch SMD devices (down to 0201 and BGA)
• Rework and modify PCBs and power modules based on engineering change orders and failure analysis results
• Safely handle high-voltage and high-current assemblies following electrical safety and ESD protocols
• Apply lockout/tagout (LOTO), proper PPE, and safe working clearances when working with energized or high-energy assemblies
• Conduct visual and functional inspection of PCBAs to ensure adherence to IPC-A-610 and IPC-7711/7721 standards
• Assist engineers with prototype power electronics builds, thermal evaluation hardware modifications, and field-return rework
• Support integration of large passive components (capacitors, inductors, bus capacitors) and power semiconductors (IGBTs, MOSFETs, SiC/GaN devices)
• Maintain detailed records of all rework and modifications for traceability
• Contribute to continuous improvement of soldering, rework, and safety processes focused on high-voltage applications
