As a Renewable Maintenance Specialist Senior, you'll take ownership of the maintenance and operational reliability of a diverse portfolio of APS-owned solar and battery energy storage systems (BESS) throughout Arizona. This hands‑on, field‑based role combines technical expertise with autonomy, offering a chance to work directly with some of the most impactful clean energy assets in the region. From inspecting and troubleshooting to commissioning and repair, you’ll ensure solar and battery systems—ranging from 2k Wac rooftop arrays to 35MWac utility‑scale installations—are operating at peak performance.

You’ll also mentor junior technicians, travel regularly statewide, and contribute to a cleaner energy future for Arizona.
