Core Responsibilities

Primary Functions

Conduct routine and preventative maintenance on all production machinery and facility equipment, following a detailed schedule to proactively identify and address potential issues before they cause costly downtime.
Respond promptly to equipment breakdowns, utilizing advanced diagnostic techniques to accurately identify root causes of mechanical, electrical, hydraulic, and pneumatic failures and execute timely repairs.
Diligently log all maintenance activities, parts usage, and repair notes into the Computerized Maintenance Management System (CMMS) to ensure accurate records and support data-driven maintenance strategies.
Interpret complex technical manuals, blueprints, electrical schematics, and mechanical diagrams to understand equipment operation and guide troubleshooting and repair processes effectively.
Perform skilled repairs on a wide range of systems, including motors, conveyors, packaging equipment, processing machinery, and other automated systems.
Adhere strictly to all company safety protocols, including Lockout/Tagout (LOTO) procedures, and actively participate in safety meetings to foster a culture of safety and accident prevention.
Utilize machine shop tools such as lathes, mills, grinders, and welding equipment to fabricate or modify machine parts when replacements are not readily available.
Execute general facility and building maintenance tasks, including basic plumbing, carpentry, and electrical work, to ensure a safe, clean, and functional work environment.
Assist in the installation, setup, and commissioning of new manufacturing equipment, ensuring it is properly integrated into existing systems and meets all operational and safety standards.
Continuously monitor equipment performance and make necessary adjustments or recommend modifications to improve efficiency, reliability, and overall equipment effectiveness (OEE).
Maintain an organized inventory of critical spare parts and maintenance supplies, initiating purchase requisitions as needed to prevent stockouts of essential components.
Perform basic troubleshooting and diagnostics on Programmable Logic Controllers (PLCs) and other automated control systems to resolve operational faults.
Conduct regular inspections of critical facility systems, including HVAC, compressed air, and fire suppression systems, to ensure they are operating correctly and in compliance with regulations.
Safely operate material handling equipment, such as forklifts and aerial lifts, to transport machinery, parts, and materials as required for maintenance tasks.
Collaborate with production teams to understand equipment issues and schedule maintenance activities in a way that minimizes disruption to production schedules.
Execute various welding, brazing, and cutting tasks using MIG, TIG, and stick welders to repair or modify equipment and structural components.
Check and maintain fluid levels, such as lubricants, coolants, and hydraulic fluids, in all machinery according to manufacturer specifications and maintenance schedules.
Complete detailed work orders and shift reports, clearly documenting problems found, actions taken, and time/materials used for each maintenance task.
Provide on-call support and respond to emergency maintenance requests outside of regular working hours as part of a rotational schedule, if required.
Provide basic technical guidance and training to machine operators on proper equipment handling, daily checks, and autonomous maintenance tasks to empower them as the first line of defense.
Participate in root cause analysis (RCA) sessions to investigate recurring equipment failures and help develop long-term corrective actions.

Secondary Functions

Support the engineering team in continuous improvement and lean manufacturing initiatives.
Assist in maintaining a clean and organized maintenance shop and spare parts storage area.
Collaborate with external service vendors and contractors, overseeing their work to ensure it meets company standards.
Participate in safety audits and contribute to the development of new safety procedures.
