Execute Maintenance and Outage Work
  • Plan, coordinate, and oversee mechanical maintenance activities
  • Support outage planning and execution with a focus on schedule adherence and efficient resource utilization

  • Mechanical work is completed safely, on schedule, and to quality standards
  • Strong collaboration exists across all disciplines, reflecting a true "One Team" culture
  • Equipment reliability and team performance show measurable improvement
