Position Summary: 

The Senior Field Quality Engineer, Energy Storage is responsible for the quality, reliability, and safety of deployed battery energy storage system (BESS) assets, independently owning failure analysis and corrective action tracking for issues identified in the field. The role works closely with operations and maintenance teams, which perform routine monitoring and maintenance, and with service engineering, which owns advanced technical escalation, as well as with design, manufacturing, and supplier quality. The position identifies systemic quality issues, conducts structured investigations, drives corrective and preventive actions, and communicates fleet performance through statistical reporting and trend analysis. This is a fully on-site role at 100 Hooper in San Francisco, with semi-regular travel to field sites. 

Essential Duties and Responsibilities 

• Serves as the primary point of contact for field-identified quality issues across operating BESS assets 

• Leads structured investigations into recurring failures, abnormal trends, and field incidents in collaboration with operations and maintenance, service engineering, design, and manufacturing 

• Performs root cause analyses using established methods such as 5 Whys, fishbone diagrams, and fault tree analysis, supported by clear problem statements, field evidence, and data 

• Defines, tracks, and verifies corrective and preventive actions, confirming effectiveness through follow-up inspections, audits, and data analysis 

• Analyzes and reports fleet performance using reliability statistics such as Weibull analysis and Nevada charts to identify failure trends and forecast field returns 

• Develops and tracks quality metrics such as repeat failure rates, defect trends, and corrective action closure
