Transmission Operations Engineer II

About the role

Arizona Public Service generates clean, reliable and affordable 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 Transmission Operations Engineer I/II supports the reliable delivery of power across APS’s transmission system by analyzing system conditions, identifying risks, and helping operators make informed, real-time decisions. Through power flow studies, contingency analysis, and real-time reporting, this role helps keep the grid stable, efficient, and responsive.

Responsibilities

• Analyze transmission system conditions using power flow, contingency, and operational studies to support real-time and future grid reliability
• Develop and deliver real-time operational reports and data insights that help our 24-hour Energy Control Center operators respond quickly to system conditions
• Perform data analysis to identify trends, constraints, and risks impacting transmission operations and market outcomes
• Support the implementation of flowgate methodology for transmission services
• Collaborate with operators, engineers, and other stakeholders to troubleshoot issues and improve operational performance
• Provide technical guidance and support to peers, and participate in on-call rotation responsibilities to support system operations
• 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
• 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
• 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

• 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

Skills

• Experience applying engineering methods and analysis in a transmission or power system operations environment
• Strong analytical skills, with the ability to interpret data and translate it into clear, actionable operational insights
• Experience supporting or working alongside real-time operations, reporting, or system monitoring activities
• Collaborative problem-solver who can work with general guidance and contribute technical input when needed
• Comfortable providing limited technical guidance and support to others
• Knowledge of power flow, contingency analysis, security constrained economic dispatch, and/or transmission services
• Familiarity with PSLF, PowerWorld, or PSSE
• Familiarity with Energy Management System (EMS) and Real-Time Contingency Analysis (RTCA)
• Familiarity with NERC Reliability Standards
• Problem analysis/resolution techniques
• Knowledge of applicable codes, standards, practices, methods and safety standards in the area of applicable engineering discipline

Schedule

Hybrid: Employees in hybrid roles work both in their home offices (virtually) and alongside their colleagues (in person). Hybrid employees are expected to work about 40% of their time in-person at an APS or other (non-home office) location. Employees are expected to reside in Arizona (or New Mexico for Four Corners-based employees).
