Staff Electrical Engineer, Energy Storage BoP
Redwood Materials · San Francisco, CA · Posted 27 days ago
Lead the electrical design of Redwood's utility-scale energy storage systems that are localizing the battery supply chain and driving the energy transition in the U.S.
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. 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. The Staff Electrical Engineer, Energy Storage BoP performs and reviews balance-of-plant power system studies, specifies major electrical equipment for Redwood’s energy storage systems, and develops protection and coordination designs. This is primarily an on-site role, with the potential for a hybrid arrangement depending on the candidate’s experience level. Some travel is also expected as part of this role.
Essential Duties and Responsibilities
- Perform and review balance-of-plant power system studies including load flow, short-circuit, protection coordination, DC and AC arc flash, transformer energization, motor starting, reactive power analysis, transient overvoltage, harmonic analysis, insulation coordination, grounding design, battery sizing, and auxiliary system sizing
- Hands-on experience with power system protection design, relay selection, settings development, and coordination studies, particularly using SEL protective relays (e.g., SEL-751, SEL-351, SEL-487E, or equivalent).
- Proficiency with SEL acSELerator QuickSet, relay configuration, protection logic development, and testing/commissioning of protection schemes for MV/HV electrical systems. Experience with ETAP, ASPEN, and/or Omicron test equipment is a plus.
- Work closely with the energy storage team to develop accurate AC and DC system models and study assumptions
- Develop, review, and validate protective relay coordination studies, relay settings, and configuration files
- Size and specify major electrical equipment including transformers, circuit breakers, switches, inverters, generators, capacitor banks, reactors, surge arresters, switchgear, current transformers, power cables, and UPS systems
- Create and maintain detailed power system models using ETAP, SKM, and/or EasyPower
- Apply industry standards, codes, and best practices to analysis results and design recommendations (IEEE, ANSI, IEC)
- Prepare clear engineering reports, study summaries, and design documentation for internal and external stakeholders
