About The Position

The Field Technician performs hands-on preventive and corrective maintenance on the Company's utility-scale solar photovoltaic (PV) and battery energy storage (BESS) equipment at Overnight Solar, a 150 MW PV facility paired with a 4-hour BESS located in Hinkley, California. Working under the direction of the Field Supervisor, the Technician carries out day-to-day field work across PV modules, inverters, trackers, combiner boxes, balance-of-plant equipment, and BESS systems, and helps ensure the safe, reliable, and efficient operation of the site. This is a full-time, hourly position based on-site at Overnight Solar. The role requires close coordination with the Field Supervisor and the Remote Operations Center (ROC), strict adherence to safety procedures around high-voltage and battery storage equipment, and the flexibility to respond to equipment alarms and emergent maintenance needs as they arise.
