BESS Electrical Development Engineer

About Redwood Materials

Redwood Materials was founded in 2017 by JB Straubel, co-founder and former CTO of Tesla, on a simple but radical idea: the critical minerals powering the energy transition already exist. They just need to come back. Today Redwood is the largest lithium-ion battery recycler in North America — recovering, refining, and redeploying critical minerals from end-of-life batteries back into the supply chain. On the energy side, Redwood has deployed the largest second-life battery project in the world, delivering power to AI data centers in months rather than years using proprietary energy architecture engineered entirely in-house. The company is profitable, the market it operates in is projected to grow 20 to 50 times over the next decade, and Redwood is the only company with the supply chain, the technology, and the operational scale to lead it.

Position Summary

Redwood Materials is deploying large-scale battery energy storage systems that power data centers and the nation's grid. Founded by Tesla co-founder and former CTO JB Straubel, Redwood closed a $425M Series E in January 2026 and was named to Fast Company's 50 Most Innovative Companies for 2026. Redwood’s energy storage business is scaling fast - we built North America's largest microgrid (63 MWh) for AI infrastructure company Crusoe, signed a partnership with GM to deploy stationary storage using both new and second-life EV batteries, and are now bringing that same battery energy storage system to Rivian's Normal, Illinois manufacturing plant.

The Senior or Staff BESS Electrical Development Engineer will join as an early member of a new engineering team working on our Battery Energy Storage System product line, specializing in BESS projects at the initiation and concept phases. This role owns the electrical and controls foundation of Redwood’s energy storage projects before detailed design and construction begin turning early, ambiguous electrical and controls inputs into a buildable concept, a defensible AC/DC design basis, and a clear interconnection and permitting path. You support active customer pursuits alongside the Business Development and Product teams - screening interconnection viability, developing preliminary single line diagrams, assessing communications network viability for Redwood’s control systems, and hardening the electrical scope and cost basis behind proposals - then hand a gap-closed electrical package to the detailed design team and its Electrical Engineer of Record. The work rewards people who move fast without sacrificing the depth that sets projects up to succeed.

Responsibilities will include:

• Lead the electrical and controls front-end scope for assigned early-phase pursuits, coordinating across Business Development, the Product team, and engineering, procurement, and construction (EPC) engineering and project controls, and serving as Business Development's electrical technical support for scope, cost, schedule, and contract exhibits.
