Core Responsibilities

Primary Functions

Expertly operate and meticulously monitor industrial kilns (rotary, tunnel, or shuttle types) via control systems (DCS/SCADA) to ensure stable and efficient thermal processing.
Continuously analyze process variables such as temperature profiles, drafts, fuel rates, and product chemistry, making precise adjustments to maintain operational stability and product quality.
Conduct comprehensive pre-shift inspections and equipment walk-downs to identify potential issues before they escalate into costly downtime.
Perform complex preventative, predictive, and corrective maintenance on all kiln-related mechanical systems, including drive trains, gearboxes, trunnion wheels, seals, and hydraulic units.
Troubleshoot and repair industrial electrical systems, including motor control centers (MCCs), variable frequency drives (VFDs), and control circuits up to 480V.
Execute detailed inspections, tear-outs, repairs, and complete installations of kiln refractory linings, including brick and castable materials, to maximize thermal efficiency.
Diagnose and maintain sophisticated combustion systems, performing burner tuning, component replacement, and ensuring optimal fuel-to-air ratios for efficiency and emissions control.
Calibrate, troubleshoot, and replace a wide variety of instrumentation, including thermocouples, pressure transmitters, gas analyzers, and flow meters.
Skillfully perform welding, cutting, and fabrication tasks as required for structural and mechanical repairs on the kiln shell and associated equipment.
Safely operate heavy mobile equipment, such as forklifts, skid steers, and loaders, to transport materials and support maintenance activities.
Diligently document all operational data, maintenance activities, and safety checks in a computerized maintenance management system (CMMS) and daily logs.
Champion and rigorously adhere to all safety protocols, including Lock-Out/Tag-Out (LOTO), confined space entry, hot work, and fall protection procedures.
Act as a first responder for any kiln-related alarms or emergencies, demonstrating a calm and methodical approach to bring the process back to a safe and stable state.
Collaborate closely with quality control personnel, providing process data and making adjustments to ensure final product consistently meets or exceeds specifications.
Lead and assist in the planning and execution of major kiln shutdown and start-up procedures, coordinating with multiple departments to ensure a safe and timely evolution.
Read and interpret complex technical documents, including mechanical blueprints, electrical schematics, P&IDs, and vendor manuals to guide troubleshooting and repairs.
Manage and maintain an inventory of critical spare parts, refractory materials, and consumables to ensure availability for planned and unplanned maintenance.
Provide on-the-job training and mentorship to junior technicians and operators, sharing expert knowledge of kiln systems and best practices.
Analyze long-term operational data trends to identify opportunities for process optimization, energy reduction, and reliability improvements.
Interface with and support external contractors and vendors during specialized repair projects or equipment upgrades.

Secondary Functions

Support ad-hoc operational data requests and contribute to exploratory analysis aimed at process optimization and root cause analysis.
Contribute to the plant's reliability and maintenance strategy by providing expert feedback on kiln performance, failure modes, and potential upgrades.
Collaborate with engineering and environmental teams to ensure ongoing compliance with all regulatory requirements and reporting standards.
Actively participate in daily toolbox talks, safety meetings, and continuous improvement initiatives within the maintenance and production departments.
