Electrical Engineer, Balance of Plant

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, switch gear, 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, switch gear, current transformers, power cables, and UPS systems
• Create and maintain detailed power system models using ETAP, SKM, and/or Easy Power
• 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 components, arc flash calculations, cable sizing, and protective device selection and coordination
• Expert proficiency in ETAP is required; experience with SKM or Easy Power is highly preferred
• Experience with grounding and cable ampacity analysis tools such as CYMCAP and CDEGS is preferred
• Working knowledge of applicable codes and standards including NEC, IEEE, and related industry practice
• Experience with battery energy storage systems (BESS), inverter-based generation, and/or data center electrical systems is a plus
• Familiarity with short circuit and protective relay software tools such as ASPEN and/or CAPE is a plus
• Familiarity with PSCAD and/or PSS®E is a plus
• Familiarity with Python for analysis automation or data processing is a plus

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

Working Conditions:

• Environment, such as office or outdoors
• Ability to work in challenging…
