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 2 kWac rooftop arrays to 35 MWac 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.

• Technical Troubleshooting – Diagnose and resolve issues across solar PV systems and battery energy storage assets to maintain operational uptime.
• System Commissioning – Lead or support the commissioning of new solar and BESS installations to ensure proper functionality and compliance with specifications.
• Installation & Repairs – Execute field installation, repairs, retrofits, and modifications to optimize system performance and longevity.
• Preventative Maintenance – Perform inspections and routine maintenance based on manufacturer, vendor, and internal O&M procedures.
• SCADA & DAS Monitoring – Utilize SCADA and Data Acquisition Systems (DAS) to monitor system health and respond to performance anomalies.
• Safety & Compliance – Adhere to safety standards and operating procedures while working with high‑voltage systems and complex energy infrastructure.
• Mentorship & Technical Leadership – Provide guidance and support to less experienced technicians, fostering knowledge sharing and safety‑first practices.
• Physical Demands & Travel – Must be capable of lifting up to 50 pounds, working in physically demanding environments, and traveling statewide as needed.

• Skilled technicians with a strong foundation in solar PV systems and BESS, and a love for hands‑on field work.
• Detail‑oriented individuals who are just as comfortable reading a SCADA screen as they are tightening a torque wrench.
• Mentors and team players who enjoy sharing knowledge and guiding others, while still learning on the job.
• Candidates who can handle the demands of outdoor, on‑site maintenance work, including climbing ladders and traveling across Arizona.
• Professionals who value safety, sustainability, and a job well done – and who want their work to make a long‑term impact in renewable energy.
• Adaptable troubleshooters who think on their feet and keep a cool head when solving technical challenges in remote or high‑demand environments.

• A two‑year associate's degree in an applicable technology area such as electric power, electronics, mechanics or hydraulics.
• Five (5) years of solar or battery storage maintenance and construction experience.
• In lieu of degree, seven (7) years of solar or battery storage maintenance, construction and/or other job‑related experience.

Preferred experience and knowledge include:

• Strong foundation in solar PV design, installation, and maintenance.
• Familiarity with battery storage technologies and systems integration.
• Experience with SCADA/DAS monitoring and HMI software.
• Understanding of NERC CIP security requirements and prerequisite background checks.
• Excellent troubleshooting, communication, and mentorship skills.
