Location: Tempe, Arizona or Southern California

Range $120,000.00-$155,000.00

The Maintenance Supervisor leads the on-site maintenance team responsible for the safe, reliable, and efficient operation of the Company's utility-scale solar photovoltaic (PV) plants in Southern California (Barstow, Hinkley, Calexico), currently comprising Imperial Sun Solar and Overnight Solar. The portfolio is expected to grow as additional PV assets under development in Southern California and Arizona reach commercial operation, and this role will play a key part in bringing those new sites into steady-state operations and maintenance.
The Supervisor directs the day-to-day work of maintenance technicians, oversees preventive and corrective maintenance across PV modules, inverters, trackers, combiner boxes, and balance-of-plant equipment, and serves as the primary on-site point of escalation for equipment failures, safety events, and performance issues. This is a full-time, position based in the Imperial Valley, with regular travel between plant sites as the portfolio expands.

• 1. Team Supervision & Workforce Management
  Supervise, schedule, and develop a team of PV maintenance technicians across Imperial Sun Solar, Overnight Solar, and additional sites as the portfolio expands.
  Assign daily work, balance staffing across sites, and ensure adequate coverage for planned maintenance, corrective work, and emergency response.
  Conduct performance reviews, one-on-ones, and skills assessments; identify training needs and support technician development and retention.
  Establish and enforce Standard Operating Procedures (SOPs), safety protocols, and work-quality standards across all supervised sites.
  Serve as the primary point of escalation for technicians on complex equipment issues or field safety concerns.
• 2. Preventive & Corrective Maintenance
  Plan and oversee preventive maintenance (PM) programs for PV modules, inverters, combiner boxes, trackers, transformers, switchgear, and balance-of-plant systems.
  Direct corrective maintenance response to equipment failures, underperformance alerts, and inspection findings to minimize downtime and lost generation.
  Review maintenance data and performance trends to identify recurring failure modes and drive root-cause analysis with O&M engineering.
  Ensure spare parts availability and coordinate with procurement/supply chain on critical components and long-lead items.
• 3. Safety, Compliance & Site Standards
  Champion a strong safety culture; ensure full compliance with Lock Out / Tag Out (LOTO), arc-flash, and high-voltage safety procedures across all sites.
  Conduct or oversee job safety analyses (JSAs), toolbox talks, and safety audits; ensure timely close-out of corrective actions.
  Ensure compliance with OSHA, NEC, and NFPA 70E requirements, plus applicable state and local environmental regulations.
  Maintain site access, security, and environmental compliance standards (stormwater, vegetation management, and habitat requirements as applicable).
• 4. Monitoring Coordination & Work Order Management
  Partner with the Remote Operations Center (ROC) / SCADA monitoring team to triage alarms, prioritize response, and confirm resolution of equipment issues.
  Ensure technicians create, update, and close SAP Plant Maintenance (PM) Work Orders, or the equivalent CMMS, accurately and on schedule.
  Monitor Work Order backlog and elevate aging or high-priority items to the O&M Manager and asset management team.
  Participate in daily and weekly maintenance planning meetings to align field activity with generation forecasts and outage schedules.
• 5. Vendor, Warranty & Contractor Management
  Coordinate on-site work performed by OEM service providers, warranty technicians, and specialty subcontractors (module, inverter, tracker, and electrical contractors).
  Track warranty claims and performance-guarantee issues; ensure timely documentation and follow-up with OEMs.
  Oversee contractor safety orientation, site access, and compliance with the Company's site rules.
• 6. Outage & Site Coordination
  Coordinate planned outages and equipment isolations with the ROC/scheduling coordinators to minimize generation loss and ensure safe system states.
  Authorize and document switching operations, clearances, and equipment isolation for field work.
  Maintain accurate records of planned work, site access, and crew activity across supervised sites.
• 7. Reporting & Documentation
  Prepare and deliver regular maintenance and performance reports (availability, Performance Ratio, Work Order cycle time, downtime causes) to the O&M Manager and asset management.
  Maintain accurate maintenance logs, inspection records, and incident reports for each site.
  Support post-event investigations and document lessons learned to prevent recurrence.
• 8. New Site Integration & Portfolio Growth
  Support the transition of new Southern California and Arizona PV sites from construction/commissioning into steady-state operations and maintenance.
  Help build out maintenance staffing plans, spare parts inventories, and SOPs for incoming sites.
  Participate in commissioning punch-list resolution, acceptance testing support, and initial performance troubleshooting for newly energized assets.
  Travel to new or existing sites as needed to support ramp-up activities and cross-train technicians across the growing portfolio
