Core Responsibilities

Primary Functions

Execute comprehensive preventive and predictive maintenance schedules on all automated material handling equipment, including high bay cranes, vertical lifts, shuttles, and conveyor systems, to ensure optimal uptime and operational efficiency.
Respond with urgency to system faults and equipment breakdowns, utilizing advanced troubleshooting methodologies to diagnose root causes across mechanical, electrical, and control systems.
Perform complex diagnostics and modifications on PLC-based control systems (e.g., Siemens S7, Allen-Bradley ControlLogix) to resolve operational faults and optimize system performance.
Troubleshoot, repair, and configure Variable Frequency Drives (VFDs), servo drives, and motor control circuits to ensure precise and reliable equipment movement.
Read, interpret, and redline complex technical documentation, including electrical schematics, mechanical blueprints, and pneumatic/hydraulic diagrams to facilitate repairs and system understanding.
Safely diagnose and repair electrical systems ranging from low voltage controls to 480V 3-phase power, adhering to all arc flash and electrical safety standards.
Conduct precise mechanical repairs and component replacements, including gearboxes, motors, bearings, chains, and precision alignment of crane and shuttle assemblies.
Utilize a Computerized Maintenance Management System (CMMS) to meticulously document all work orders, log repair details, manage parts inventory, and track equipment history for trend analysis.
Perform regular inspections and maintenance of the high bay infrastructure, including running rails, power rails, and structural steel, to identify and mitigate potential safety or operational risks.
Calibrate and replace a wide variety of industrial sensors, such as photo-eyes, proximity sensors, encoders, and laser distance meters, to maintain system accuracy.
Adhere rigorously to all site-specific safety protocols, with a strong emphasis on Lock-Out/Tag-Out (LOTO), fall protection, and working-at-heights procedures.
Collaborate directly with control room operators and operations leadership to effectively communicate equipment status, coordinate maintenance windows, and minimize impact on production.
Operate and maintain certification for various aerial work platforms, including scissor lifts and articulating boom lifts, for safe access to equipment at height.
Identify and recommend opportunities for continuous improvement in equipment design, maintenance strategies, and operational processes to enhance system reliability and safety.
Manage an inventory of critical spare parts, ensuring availability for emergency repairs by identifying reorder points and sourcing components.
Perform basic welding and fabrication tasks to repair or strengthen non-critical brackets, guards, and structural components.
Support the installation, commissioning, and testing of new or upgraded automation equipment, often working alongside vendor technicians and project engineers.
Maintain and troubleshoot the Warehouse Control System (WCS) and its interface with the PLC layer, diagnosing communication and data flow issues.
Conduct battery maintenance, charging, and replacement for automated guided vehicles (AGVs) or shuttle systems as required by the facility's technology.
Maintain a professional and organized work environment, including maintenance workshops, parts storage, and any area where work is performed.

Secondary Functions

Assist in the development and delivery of technical training for new technicians, maintenance apprentices, or operations personnel.
Contribute to facility-wide safety programs, participating in safety committee meetings and conducting peer safety audits.
Generate and present basic reports on equipment downtime, maintenance key performance indicators (KPIs), and parts consumption using data from the CMMS.
Provide cross-functional support to other maintenance teams, such as conveyor or facilities maintenance, during periods of high demand or critical need.
