Opportunity Summary

The Operations and Maintenance (O&M) Manager will primarily support Rayburn Energy Station 2 (RES
2) with an initial focus on pre-commissioning, startup, system turnover, workforce readiness, and transition to commercial operation.

Once commercial operation begins, the O&M Manager will oversee the safe, reliable, efficient, and environmentally compliant operation and maintenance of RES 2. This role leads plant personnel, supports real-time grid responsiveness, and drives performance through maintenance planning, reliability improvement, outage execution, personnel development, regulatory compliance, and financial stewardship.

As part of the broader Rayburn Energy Station management team, the O&M Manager will also provide support to Rayburn Energy Station I (RES I) as needed. This support is intended to promote an integrated, one-team approach across the site and may include coordination of personnel, maintenance activities, outages, training, and other operational priorities.

• Lead commissioning, startup, system walkdowns, turnover reviews, testing, troubleshooting, punch-list resolution, performance testing, and operational readiness activities.
• Coordinate with the Plant Manager, Owner, EPC/Engineer of Record, OEMs, commissioning teams, vendors, and plant personnel to support safe system turnover and transition to commercial operation.
• Develop and validate operating and maintenance procedures, commissioning documentation, system descriptions, training materials, and other technical documentation required for startup and ongoing operations.
• Establish workforce qualification requirements and support implementation of the CMMS, equipment hierarchy, preventive and predictive maintenance programs, critical spare-parts inventory, and long-term maintenance and reliability strategies.

Your scope of responsibility as O&M Manager includes the following primary functions:

• Promote a strong safety culture and ensure employees, contractors, and vendors comply with established safety, environmental, regulatory, LOTO, and hazardous-energy control requirements.
• Lead, coach, and develop operations and maintenance personnel while establishing clear expectations for performance, procedural compliance, teamwork, accountability, and professional development.
• Oversee the safe, reliable, and efficient operation and maintenance of Siemens SGT-800 combustion turbines, generators, electrical systems, emissions-control systems, and associated balance-of-plant equipment.
• Maintain readiness for fast-start and dispatch-driven operation by balancing equipment condition, operating limitations, maintenance requirements, cycling impacts, personnel resources, availability, and response capability.
• Analyze operating and maintenance data, starts, outages, alarms, equipment trends, and maintenance history to improve start reliability, reduce forced outages, and identify cost-effective reliability improvements.
• Direct root cause analysis and corrective actions for equipment failures, start failures, forced outages, and abnormal operating conditions while continuously improving preventive, predictive, and corrective maintenance programs.
• Plan and coordinate maintenance activities and outages, including work scope, scheduling, resources, contractor oversight, LOTO, quality control, testing, and safe return to service.
• Manage effective use of the CMMS for work planning, scheduling, preventive maintenance, backlog management, equipment history, maintenance reporting, and asset reliability.
