Engineer III​/Senior - Predictive Maintenance

Arizona Public Service generates reliable, affordable and clean energy for 2.7 million Arizonans. As the state's largest and longest-serving energy provider, our more than 6,000 dedicated employees power our vision of creating a sustainable energy future for Arizona.

The Predictive Maintenance Engineer III / Senior Engineer provides advanced technical expertise in the development, implementation, and continuous improvement of predictive and preventive maintenance programs for power generation assets. This role is responsible for ensuring the reliable operation of critical rotating equipment-including steam turbines, gas turbines, pumps, fans, and pulverizers, through the application of industry best practices and advanced diagnostic technologies.

This position applies in-depth engineering knowledge to complex technical challenges, construction projects, and emergent equipment issues. The engineer is regularly relied upon as a subject matter expert in one or more predictive maintenance disciplines, with a strong understanding of engineering technologies, maintenance processes, and system performance. Solutions developed in this role are often used as the final technical basis for operational and maintenance decisions, with work evaluated primarily on long-term results and impact.

• Lead the development, implementation, and oversight of predictive maintenance (PdM) programs across multiple generating facilities
• Analyze and interpret condition monitoring data using techniques such as:
  • Vibration analysis
  • Oil analysis
  • Thermography
  • Ultrasound and acoustics
  • Motion capture and other advanced diagnostics
• Maintain and manage data within web-based PdM systems and databases
• Review and apply OEM technical alerts, recommendations, and equipment‑specific testing protocols
• Develop new monitoring methods, tools, and strategies to enhance equipment reliability and performance
• Provide mentorship and technical guidance to other personnel on PdM practices and technologies
• Support troubleshooting and resolution of complex equipment issues across multiple plants

• Coverage of multiple plant sites across the greater Phoenix area and extending to Yuma, including Arlington, Phoenix, Tempe, Coolidge, Marana, and Yuma
• Primary office location in downtown Phoenix
• Approximately 40-50% fieldwork (on-site) and 50-60% office‑based work, with a minimum 40% in‑person requirement
• May be subject to shift work depending on operational needs
