Redwood Materials, founded by JB Straubel (Tesla co-founder and former CTO), is North America's largest lithium-ion battery recycler and a leader in second-life battery energy storage. The company has deployed the world's largest second-life battery project, delivering power to AI data centers using proprietary in-house engineered energy architecture. Redwood is profitable and positioned to lead a market projected to grow 20–50x over the next decade.
The Staff Electrical Engineer, Energy Storage BoP will perform and review comprehensive balance-of-plant power system studies, specify major electrical equipment for energy storage systems, and develop protection and coordination designs. This is primarily an on-site role with potential for hybrid arrangements based on experience; some travel is expected.
Key responsibilities include:
- Perform and review balance-of-plant power system studies: load flow, short-circuit, protection coordination, DC/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 power system protection design, relay selection, settings development, and coordination studies using SEL protective relays (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
- 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: 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 (IEEE, ANSI, IEC) to analysis results and design recommendations
- Prepare clear engineering reports, study summaries, and design documentation for internal and external stakeholders
Requirements:
- 5+ years of experience performing power system analysis, including protection and coordination studies
- MS or PhD in Electrical Engineering with specialization in power systems
- Strong foundation in power system analysis: fault calculations, symmetrical components, arc flash calculations, cable sizing, and protective device selection and coordination
- Expert proficiency in ETAP (required); experience with SKM or EasyPower (highly preferred)
- Working knowledge of applicable codes and standards: NEC, IEEE, and related industry practices
- Experience with grounding and cable ampacity analysis tools such as CYMCAP and CDEGS (preferred)
- Experience with battery energy storage systems (BESS), inverter-based generation, and/or data center electrical systems (a plus)
- Familiarity with short circuit and protective relay software tools such as ASPEN and/or CAPE (a plus)
- Familiarity with PSCAD and/or PSS/E (a plus)
- Familiarity with Python for analysis automation or data processing (a plus)
