Staff Electrical Engineer, Balance of Plant

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 components, arc flash calculations, cable sizing, and protective device selection and coordination

Expert proficiency in ETAP is required; experience with SKM or EasyPower 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 working conditions which may include exposure to noise, dust, chemicals, and temperature extremes, while protected by PPE, for extended periods of time

Essential physical requirements, such as climbing, standing, stooping, or typing

Occasional work weekends, nights, or be on-call as a regular part of the job

Occasional travel requirements
