This level is expected to independently diagnose difficult mechanical, electrical, controls, HVAC, pneumatic, hydraulic, fabrication, and facility infrastructure issues; lead corrective action efforts; improve preventive maintenance strategies; and support operational uptime through advanced technical judgment and leadership.
Core Responsibilities

Lead advanced troubleshooting and repair of critical production equipment, facility systems, building infrastructure, HVAC systems, refrigeration support equipment, power transmission systems, controls, pumps, motors, conveyors, and automated equipment.
Serve as a technical resource for Level I and Level II technicians, operations teams, supervisors, vendors, contractors, and engineering support.
Perform and lead root cause analysis for repeat failures, major downtime events, safety-related failures, and high-cost repairs.
Develop corrective action plans that address the true cause of failure, reduce recurrence, improve uptime, and extend asset life.
Evaluate equipment performance trends using CMMS history, PM results, downtime records, vibration, temperature, electrical readings, inspection findings, and operator feedback.
Recommend changes to preventive maintenance frequencies, inspection criteria, spare parts, lubrication practices, equipment standards, and reliability procedures.
Lead or support installation, commissioning, alignment, testing, and startup of new equipment or modified systems.
Perform advanced fabrication, welding, layout, precision measurement, field fitting, guarding improvements, and equipment modification within approved standards.
Assist with contractor coordination, job planning, technical scope development, parts identification, and repair prioritization.
Train, coach, and evaluate technical skill development for lower-level technicians without replacing formal supervisory performance review responsibilities.
