Generation Plant Engineer II​/III​/Senior - Mechanical

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.

Engineer II performs engineering design, modifications, and economic and analytical support with general guidance, applying established engineering methods while developing technical judgment and providing limited guidance to others.

Engineer III builds on this foundation by working more independently, contributing to long‑range system planning, proposals, and presentations, and taking increased responsibility for technical decisions and interpretations while regularly providing technical leadership.

Engineer Senior applies in‑depth expertise to highly complex projects and emergent issues, serves as a recognized technical authority with broad or specialized knowledge, establishes the most effective solutions, and is relied upon for final technical decisions with work reviewed primarily for long‑term results rather than methods.

Engineer Senior

• A four‑year Bachelors degree in an engineering discipline or related applied science discipline (see approved list) from an ABET accredited institution, an International Engineering Alliance (IEA) recognized institution or an ABET Mutual Recognition Agreement (MRA)
• Plus eight (8) years working experience in Engineering‑related positions.

Approved degrees:
Materials Science/Metallurgy, Physics, Chemistry, Nuclear, Electrical, Mechanical, Civil, Electronics, Computer Science, Environmental, Chemical, Structural. (A four‑year bachelor of Engineering Technology degree is not considered an automatic equivalent for a B.S. degree in Engineering. A review of the degree program curriculum must be completed by Engineering department management.)

• Analyzes and prepares a variety of data, technical reviews and evaluations, trend analyses, short to long‑range technology assessments, products and services, investigations, product/specification verifications to aid decision making. May present findings to a diverse group of management, internal staff, customers, vendors, etc.
• Identifies, communicates and advocates resolution of technical concerns while adhering to sound engineering principles during evaluation / resolution of the conditions. Challenges conditions and decisions when needed to ensure plant systems, engineering designs, project controls and oversight of work has high technical quality, is cost effective, in compliance with established standards, codes and regulations, maintains future reliability, satisfies customer requirements, budget and schedules to meet or exceed all reasonable or agreed upon customer service levels.
• Interfaces with customers or cross organizational team members to assess their needs, determine the scope of the project, obtain necessary data to make key decisions which may require consultation with external or internal customers or employees.
• May provide oversight of engineering technical programs by managing the program requirements, working with cross organizational partners, reviewing and internalizing operating experience and coordinating corrective actions to ensure engineering program elements continue to remain healthy.
• Provides support for projects and modifications that will increase operating efficiency. May review design…
