Field Service Technician, Solar and Battery Storage

Redwood Materials is seeking a Field Service Technician to support the safe, reliable, and efficient operation of our growing fleet of Energy Storage Systems (ESS) across remote and regional field locations. This role is critical to our mission by ensuring maximum uptime of battery storage installations through proactive maintenance, rapid troubleshooting, and field repairs.

You will travel extensively (up to 75%) to remote ESS sites, perform hands-on electro-mechanical service work with minimal oversight, and contribute to continuous improvement in a fast-paced environment. Solar experience is a plus but secondary to core battery storage expertise.

Essential Duties and Responsibilities:

• • Field Service & Maintenance:
    • Travel up to 75% to remote ESS installations to deliver expert-level field repairs, comprehensive maintenance, and advanced system troubleshooting of battery storage equipment, including electrical, mechanical, power electronics, and control systems.
    • Execute routine and preventative maintenance, inspections, and commissioning of battery storage systems.
    • Respond to service requests, complete work orders, and maintain detailed documentation of activities..
  • Project & Contractor Oversight:
    • Manage on-site field projects and coordinate with contractors/third-party vendors.
    • Develop and refine standard work instructions (SWIs) for field service tasks.
  • Safety & Continuous Improvement:
    • Identify and mitigate safety hazards, particularly in high-voltage battery environments.
    • Collaborate cross-functionally with operations, engineering, and EHS teams to implement process improvements.
    • Operate specialized tools and diagnostic equipment safely and effectively.
  • General Support:
    • Complete daily task lists and support scaling of ESS deployments.
    • Thrive in dynamic outdoor and variable-temperature field conditions.

Skills, Knowledge, and Abilities:

• Strong electro-mechanical troubleshooting and repair skills with preference for battery storage / ESS systems.
• Solid background in electrical systems (high/low voltage), inverters, BMS, and mechanical maintenance.
• Ability to work independently with a self-motivated, safety-first mindset in remote locations.
• Proficiency with tools, diagnostic equipment, and field service documentation.
• Physical ability to lift/carry up to 50 lbs., climb, bend, and perform tasks in varied field environments.
• Valid driver’s license and clean driving record.
• Passion for sustainability and advancing the energy transition.
