• Support the development of audit-ready documentation, operational logs, and reporting templates for seamless CCC handover from EPC to Operations.


• Establish and configure the site CMMS during the commissioning phase, developing asset structures, preventive maintenance programs, equipment records, and work order management processes to support long-term reliability and efficient maintenance execution.


• Oversee initial commissioning and functional validation of critical systems, including DCS/HMI verification, alarm rationalization, and equipment start/stop sequences.


• Establish initial compliance frameworks for NERC, environmental, safety, and water chemistry programs.


• Coordinate with Operations and Engineering to ensure all maintenance procedures, logs, and parts management systems are ready for safe and reliable plant startup.

Your scope of responsibility as Maintenance Manager includes the following primary functions:

• Oversee maintenance personnel to ensure safe, efficient, and high-quality performance of maintenance and repair work in alignment with company policies, procedures, and technical specifications.


• Foster a strong safety culture, including maintaining records, implementing incentive programs, and ensuring compliance with the Plant Safety Manual and regulatory requirements.


• Implement, manage, and track preventive, predictive, and corrective maintenance programs; analyze equipment performance and failure trends to support operational reliability and continuous improvement.


• Serve as Project Manager for maintenance projects, coordinating activities, scheduling, monitoring performance, and providing technical expertise to complete tasks safely and efficiently.


• Develop and manage budgets, contracts, and work scopes for internal staff and external contractors to optimize resource utilization and ensure timely project completion.


• Provide detailed task lists, schedules, and work-order-level guidance during normal operations, planned outages, and forced outages, ensuring availability of parts, tooling, and services.


• Maintain accurate records in the CMMS, including work orders, historical data, and maintenance schedules to support future planning and continuous improvement initiatives.


• Collaborate with Operations, Engineering, and NERC coordinators to enhance maintenance planning effectiveness, ensure compliance, and complete tasks with proper documentation.


• Ensure maintenance manuals, OEM guides, and plant records are current, and oversee warehouse and inventory management to maintain efficient material availability and utilization.


• Lead initiatives to improve plant performance, including reliability, heat rate, and availability, while reducing corrective maintenance needs.


• Participate in the development, implementation, and ongoing refinement of plant policies, objectives, and long-term maintenance planning strategies.


• Promote positive community and environmental engagement by encouraging maintenance staff participation in outreach and plant stewardship activities.
