BESS Development Engineer, Senior or Staff

Redwood Materials is building grid-scale Battery Energy Storage Systems (BESS), and this role shapes those projects before detailed design and construction begin. As the Electrical Engineer on the Energy Storage Project, you take early, ambiguous inputs and turn them into a buildable scope, a concept design, and a clear permitting and interconnection path. You support active customer pursuits alongside the Business Development and Product teams, then hand a gap-closed engineering package to the detailed design team for execution. The work rewards people who move fast without sacrificing the depth that sets projects up to succeed.

Responsibilities will include:

• Produce concept layouts, preliminary single line diagrams, and feasibility studies that confirm buildable area, interconnection viability, and a clear permitting path for early-phase battery energy storage projects
• Serve as the technical engineering, procurement, and construction (EPC) point of support for Business Development, supplying scope boundaries, buildability constraints, cost and schedule inputs, and the technical exhibits attached to customer contracts
• Coordinate civil, structural, electrical, architectural, and fire protection engineering disciplines to set the design basis, review studies and layouts, and assemble concept packages against pursuit schedules
• Identify and document viable permitting and interconnection pathways, timelines, and critical site requirements, including zoning, stormwater, environmental constraints, noise limits, and site security and access
• Drive the data and information request checklist to closure, assigning an owner to every item, tracking status, and surfacing scope ambiguities and long-lead items
• Document scope delineation across internal and external responsible parties and deliver the scope and Basis of Design package that formally hands the project to the detailed design team
• Own internal and external engineering resourcing and schedule for assigned early-phase work

Desired Qualifications:

• Bachelor's degree in Engineering, preferably Civil or Electrical, or equivalent experience demonstrating exceptional ability in these fields
• Deep understanding of grid-scale energy storage technologies and balance-of-plant equipment such as inverters, transformers, switchgear, and fire detection systems
• Strong working knowledge of electrical system design, utility interconnection requirements, and utility-scale project execution, including medium and high voltage systems
• Familiarity with relevant standards and codes, including UL 9540, UL 1973, UL 1741, IEEE, NEC, NFPA, and IEC
• Experience coordinating multi-disciplinary scopes within architecture/engineering or design engineering firms, with at least 5 years' experience desired
• Project management and/or EPC experience, including commercial or industrial electrical installations and electricity distribution systems
• Professional Engineer (PE) license preferred
• Strong communication skills, excellent attention to detail, and the ability to prioritize and execute tasks in parallel in ambiguous, fast-moving environments
• A passion for sustainability and making the world a better place!
