• Ensure work packages include the labor, materials, tools, technical information, and safety controls needed for successful execution.
• Improve equipment availability, reduce recurring failures, and lead root-cause investigations and corrective actions.
• Manage maintenance budgets, contractor performance, critical spare parts, and repair costs in partnership with Supply Chain.
• Strengthen CMMS discipline and use performance measures to improve preventive maintenance completion, schedule compliance, backlog quality, and maintenance costs.
• Maintain a strong field presence and reinforce energy isolation, electrical safety, pre-task planning, environmental protection, and stop-work expectations.
• Support new equipment installations, commissioning, and the integration of new assets into maintenance programs.
What you bring
• At least 10 years of progressive maintenance experience in mining, mineral processing, chemical processing, power generation, or comparable heavy industry.
• At least five years of supervisory or maintenance leadership experience.
• Working knowledge of both industrial mechanical and electrical maintenance systems.
• Experience developing preventive maintenance programs and coordinating outages, major repairs, and maintenance execution.
• Demonstrated ability to manage budgets, contractors, materials, and equipment reliability initiatives.
• Proficiency with a CMMS, maintenance reporting, and technical documentation.
• Strong leadership, coaching, communication, planning, and problem-solving skills.
• A high school diploma or GED. Relevant technical training and substantial practical experience are valued; a bachelor’s degree is not required.
• A valid driver’s license and the ability to meet company vehicle-operation requirements.
Experience that will help you stand out
• Direct experience in open-pit copper, heap-leach, hydrometallurgical, or SX/EW operations.
• Leadership of maintenance supervisors and planners.
• Experience with pumps, conveyors, crushing systems, motors, drives, electrical distribution, instrumentation, and process-fluid equipment.
• Familiarity with MSHA requirements, NFPA 70E practices, and SAP, Maximo, or comparable CMMS software.
• Technical education, an industrial maintenance apprenticeship, or a related degree.
• Experience improving reliability during a startup, production ramp-up, or facility expansion.
Why Gunnison Copper?
You will have the opportunity to build team capability, strengthen maintenance practices, and see the results of your leadership in the field.
