Battery Storage Technician

Job Description

Battery Storage Technician plays a crucial role in CES’s mission to deliver reliable, high-quality services for renewable energy assets. Technicians perform routine and corrective maintenance on battery storage assets to ensure they operate at peak efficiency. CES emphasizes training and career development, positioning our technicians as some of the most technically capable in the industry.

Because CES serves projects across multiple regions, technicians are hired with the expectation that they will regularly travel from place to place to work. Assignments frequently require staying near project locations to ensure reliable daily access to the site. This role therefore involves frequent travel both in and out of state, along with close collaboration with other CES field technicians to deliver best-in-class service to our customers.

Key Responsibilities

• Lead field crews in performing battery storage system work safely, efficiently, and in accordance with CES’s code of conduct.
• Perform and support installations, commissioning, troubleshooting, and repairs of battery energy storage systems.
• Conduct system checks, collect data, and adjust settings on computerized equipment.
• Follow standard operating procedures and supervisor direction; stop and seek clarification anytime a task appears unsafe.
• Adhere to all lockout/tagout procedures.
• Prepare detailed documentation—including photos—on all work performed, issues encountered, parts used, suspected root causes, and site conditions.
• Foster a culture where every team member feels empowered to stop work when the sequence or conditions are unclear or unsafe.
• Perform quality assurance inspections on newly onboarded BESS sites.
• Support continuous improvement initiatives and help identify opportunities where CES can elevate its quality and efficiency.
• Maintain excellent housekeeping standards at all times.
• Perform other duties as assigned.
