This position is designed for experienced technicians with advanced diagnostic and repair capabilities on heavy construction, mining, engineering, and earthmoving equipment. This is not a fleet-management or primarily supervisory position. The company needs technicians who are comfortable working directly on equipment, troubleshooting complex failures, performing major component replacements, and maintaining equipment reliability in a demanding operating environment.

The maintenance team supports approximately 32 pieces of mobile equipment, including large wheel loaders, dozers, haul trucks, water trucks, service trucks, and other heavy support equipment.

Responsibilities

• Diagnose, troubleshoot, repair, and maintain heavy mobile mining and earthmoving equipment.
• Perform hands-on maintenance on diesel engines and powertrains.
• Troubleshoot and repair hydraulic systems.
• Diagnose electrical and electronic equipment failures.
• Repair powertrain and driveline components.
• Perform major component replacements and equipment repairs.
• Use electronic diagnostic platforms such as CAT ET, John Deere Service Advisor, Jaltest, or comparable systems.
• Perform field troubleshooting and repairs to minimize equipment downtime.
• Support preventive and corrective maintenance requirements across a fleet of approximately 32 mobile assets.
• Work directly on large wheel loaders, dozers, haul trucks, water trucks, service trucks, and other heavy support equipment.
• Contribute directly to fleet availability, reliability, and overall mining operations.

• Operate, adjust, and monitor blowers, gas pretreatment equipment, chillers, compression systems, scrubbers, purification equipment, pumps, valves, and related process equipment.
• Complete daily equipment rounds and inspect flow meters, gas chromatographs, fluid levels, pressures, temperatures, vibration, noise, and other operating conditions to identify problems before failure occurs.
• Tune and adjust plant systems to support production, process stability, efficiency, and environmental compliance.
• Diagnose mechanical, electrical, instrumentation, and process issues using SCADA, technical manuals, operating data, schematics, and systematic troubleshooting methods.
• Perform preventive and corrective maintenance including oil and filter changes, drive belt and hose replacement, valve adjustments, compressor filter service, slide valve work, coupling and bearing replacement, and related repairs.
• Participate in preventive maintenance outages, equipment overhauls, startups, shutdowns, and emergency repairs.
• Coordinate maintenance activities with management, operators, and third-party vendors to ensure timely and efficient service.
• Maintain accurate records for production data, equipment operating hours, service schedules, maintenance activities, equipment outages, and operating changes.
• Respond to callouts in a timely manner, identify the cause of the issue, correct the condition when possible, and escalate unresolved problems to plant leadership.
• Maintain organized inventories of parts, tools, chemicals, and operating supplies while keeping the plant and surrounding work areas clean and presentable.
• Follow all site safety, environmental, quality, lockout/tagout, hazardous material, and Class I Division 2 operating requirements.

Must-Have Skills, Experience, and Education

• High school diploma or GED; technical school, military technical training, or equivalent hands-on experience is strongly valued.
• At least 3 years of hands-on industrial operations, process equipment, mechanical maintenance, utility, power-generation, oil and gas, pipeline, refinery, chemical, wastewater, food, pharmaceutical, or manufacturing experience.
• Strong mechanical aptitude and refined troubleshooting ability with pumps, blowers, compressors, valves, bearings, couplings, hoses, filters, motors, or other rotating and fluid-handling equipment.
• Working knowledge of process flow and the relationship between pressure, vacuum, temperature, fluid level, and flow.
