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. Our present and future success depends on the creative and dedicated people of our company who demonstrate the principles outlined in the APS Promise: Design for Tomorrow, Empower Each Other and Succeed Together. Are you ready to shape the future of power generation projects? As a Design Systems Engineer, you'll play a key role in ensuring the reliability, safety, and efficiency of APS's non-nuclear generation assets. Using your technical expertise and power plant knowledge, you'll evaluate system and component health, identify improvement opportunities, and develop the scope, cost, and schedule for capital projects that will sustain plant performance for years to come. Working closely with plant personnel, engineers, and third-party service providers, you'll create detailed project justifications and risk analyses that guide the Generation Capital Budget and 10-year long-range forecast. This is a strategic, high-impact role where your engineering insight directly influences operational reliability and long-term planning.
