Staff BESS Electrical Design Engineer, EPCActive$190K

Redwood Materials was founded in 2017 by JB Straubel, co-founder and former CTO of Tesla, on a simple but radical idea: the critical minerals powering the energy transition already exist. They just need to come back.

What you'll do

• Lead electrical engineering efforts for utility scale lithium-ion BESS: projects from concept (system sizing, layout) through construction.

• Interface with utilities and ISO/RTOs to support interconnection: studies/submittals, permitting, and compliance for new renewable and BESS projects.

• Serve as the internal subject matter expert (SME) for technical challenges related to BESS.

• Design AC and DC electrical systems for BESS using medium voltage: transformers, inverters, DC combiners, energy managers, and battery modules. Specify and procure long-lead AC equipment.

• Develop schematic diagrams, single-line diagrams, wiring schematics, raceway: plans, grounding plans, and protection strategies for AC and DC systems.

• Specify and evaluate components such as circuit breakers, contactors, fuses,: disconnects, emergency power off (EPO), and metering devices.

What they're looking for

• Coordinate with civil, structural, fire & life safety, SCADA/telecom,: geotechnical, and DC system design teams to produce complete IFC packages and technical specifications.
• Ensure designs comply with applicable codes and standards such as NEC 705,: NEC 706, IEEE 1547, UL 9540, NFPA 855, and local amendments. Lead code reviews and provide summary to internal teams.
• Integration of BESS with grid infrastructure and other renewable and traditional energy sources.
• Perform power system studies for short circuit, load flow, arc flash, and: protective device coordination for AC and DC systems.
