Senior Service Engineer, Energy Storage

Position Summary: 

The Senior Service Engineer, Energy Storage resolves complex technical issues across deployed battery energy storage systems (BESS). The role serves as the technical escalation path for the operations and maintenance organization, which handles routine monitoring, preventive maintenance, and first-line troubleshooting. The position independently owns deep diagnostics, system-level failure analysis, and engineering-driven corrective actions. It bridges field operations and engineering by translating operational issues into engineering solutions and feeding field learnings back into product and system design. This is a fully on-site role at 100 Hooper in San Francisco, with semi-regular travel to field sites. 

Essential Duties and Responsibilities 

• Acts as the primary technical escalation point for the operations and maintenance organization for issues beyond standard operating procedures 

• Defines handoff criteria, escalation thresholds, and response expectations between operations and maintenance and service engineering 

• Owns investigation and resolution of complex electrical, controls, software, thermal, and system-integration issues 

• Translates field and operations and maintenance feedback into actionable requirements for product, systems, and research and development engineering teams 

• Drives improvements in system serviceability, reliability, and maintainability in collaboration with design, manufacturing, and quality engineering 

• Owns advanced service documentation, including troubleshooting guides, decision trees, and service bulletins
