About the role

Critical Loop is looking for a Master Electrician with deep experience in utility-scale Battery Energy Storage Systems (BESS) to lead the electrical execution of our field deployments. This role will serve as the technical expert for installation, commissioning, troubleshooting, and service activities across our battery storage fleet. This is a hands-on leadership role. We're looking for someone who is just as comfortable troubleshooting a live system as they are mentoring junior electricians, making field decisions, and partnering with engineering to solve complex problems.

• Hands-on experience with inverter installation and commissioning — EG4, SMA, Sungrow, SolarEdge, or comparable platforms.
• Strong understanding of battery systems, including series and parallel configurations, battery management systems (BMS), phase rotation, multi-phase commissioning, arc flash, and DC electrical hazards.
• Experience performing lockout/tagout (LOTO), live-dead-live verification, and electrical testing using multimeters, insulation resistance testers, and phase rotation meters.
• Ability to read and interpret electrical schematics, one-line diagrams, wiring diagrams, and technical documentation.
• Valid driver's license and ability to travel as needed.
• SCADA, Modbus, or BMS communications troubleshooting experience.
