San Francisco, CA | Full-Time | $190,000 – $252,500
The Opportunity
Every megawatt-hour of grid storage that comes online needs an engineer who understands both sides of the inverter. Our client — a rapidly scaling clean energy innovator — is hiring a Staff BESS Electrical Design Engineer to lead utility-scale lithium-ion storage projects from first concept through energization. As Electrical Engineer of Record and the company's internal BESS authority, you'll shape how grid-scale batteries get designed, interconnected, and built — with top-of-market compensation to match the responsibility.
Why You'll Love It

- Complete design scope: AC and DC systems, from battery modules to the utility interconnection
- Push the frontier: Lead R&D into MV-DC distribution for next-generation storage integration
What You'll Do
- Lead utility-scale lithium-ion BESS engineering — system sizing and layout through construction
- Design AC and DC systems with MV transformers, inverters, DC combiners, energy managers, and battery modules; specify and procure long-lead equipment
- Develop schematics, single-lines, wiring diagrams, raceway and grounding plans, and protection strategies
- Interface with utilities and ISO/RTOs on interconnection studies, submittals, permitting, and compliance
- Lead code compliance across NEC 705/706, IEEE 1547, UL 9540, and NFPA 855
- Perform short circuit, load flow, arc flash, and protective device coordination studies for AC and DC systems
- Serve as Electrical Engineer of Record for assigned projects
- Coordinate civil, structural, fire & life safety, SCADA/telecom, and geotech teams into complete IFC packages
- Support construction administration — RFIs, submittals, change orders, site inspections
- Prepare cost estimates and schedules, QA/QC designs, mentor junior engineers, and set design standards
What You'll Bring
- BS/MS in Electrical Engineering (ABET)
- Active PE (Nevada or reciprocity-eligible); NV and SC licensure within 2 months of start
- 5+ years in solar, energy storage, or microgrids, including 3+ in BESS design and deployment
- Proven BESS interconnection and regulatory compliance expertise
