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
