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: 

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.

  • 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 
  • Drives continuous improvement initiatives that reduce operational burden on operations and maintenance and improve system reliability 

Skills, Knowledge, and Abilities  

  • Bachelor's degree in Electrical or Mechanical Engineering or a related technical discipline 
  • 5+ years of experience in field quality, reliability engineering, service engineering, or commissioning support for complex electromechanical or energy systems such as BESS, power electronics, renewable energy, or industrial electrical equipment 
  • Experience working safely on high-voltage AC and DC systems, including applicable electrical safety practices 
  • Working knowledge of root cause analysis methods and corrective and preventive action processes 
  • Working knowledge of reliability statistics, including Weibull analysis, Nevada charts, and failure rate trending 
  • Experience working directly with field operations, technicians, and service engineering teams, including field inspection procedures, commissioning documentation, and service records 
  • Valid driver's license and ability to travel up to 25% of the time
