POSITION: MECHANICAL MAINTENANCE SUPERVISOR

The Mechanical Maintenance Supervisor provides day-to-day leadership and technical oversight of mechanical maintenance activities at Greenfire’s SAGD central processing facilities (CPFs), well pads and associated infrastructure. The position ensures that preventive, corrective and emergent work on rotating and stationary equipment is executed safely, efficiently and to applicable technical standards. Working closely with Operations, Maintenance Planning, Reliability, Supply Chain and third-party service providers, the Supervisor assigns work, manages field execution, addresses equipment issues and supports asset reliability, regulatory compliance and cost-conscious maintenance delivery.

This is a full-time, permanent position based out of Greenfire Resources Fort McMurray Production Facility based on a 7/7 or 14/14 rotation.

Work Management, Planning & Maximo

· Partner with planners and schedulers to prioritize corrective and preventive maintenance, develop executable work scopes, establish resource estimates and align work with operating windows.

· Review work packages for materials, critical spares, labour, permits, tools, equipment, vendor support and technical information before scheduling.

· Use Maximo to review work orders, confirm execution status, capture labour and failure information, maintain equipment history and ensure timely, accurate work-order closeout.

· Identify preventive-maintenance and predictive-monitoring improvements, equipment data gaps, critical spare requirements and opportunities to improve work-management processes.

· Participate in shutdowns and turnarounds, including scope development, job sequencing, contractor oversight, execution tracking and post-event lessons learned.

Cost, Projects & Continuous Improvement

· Monitor maintenance labour, overtime, consumables and contractor expenditures against approved plans; identify schedule and cost variances and recommend corrective actions.
