Staff Electrical Engineer, Balance of Plant
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. Summary: The Staff Electrical Engineer, Balance of Plant (BoP) will focus on the design, modeling, and protection of the electrical infrastructure supporting Redwood’s utility-scale Battery Energy Storage Systems (BESS). This role is responsible for executing critical power system studies, including load flow, short-circuit, protection coordination, and arc flash analysis, while sizing major electrical equipment like transformers, switchgear, and protective relays. You will bridge high-voltage grid requirements with system-level BESS architectures, ensuring all installations comply with NEC, IEEE, and local utility codes. At Redwood Materials, we aren't just recycling batteries, we are building the utility-scale infrastructure that will power the future clean energy grid. As a Staff Electrical Engineer, BOP, you will own the electrical design, modeling, and safety coordination for our GWh-scale energy storage sites. If you have deep expertise in commissioning microgrids, a strong grasp of protective relay coordination, and want to build the physical backbone for a circular energy economy, this is your opportunity to shape the grid of tomorrow. Responsibilities will include: 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 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 Desired Qualifications: 3+ years of direct experience designing and commissioning PV and BESS systems. MS or PhD in Electrical Engineering with specialization in power systems Strong foundation in power system analysis including fault calculations, symmetrical c...
