Core Responsibilities

Primary Functions

Perform precision installation, alignment, shimming, and leveling of motors, gearboxes, pumps, conveyors, presses, and other plant machinery using lasers, dial indicators, feeler gauges, and precision measuring tools to meet OEM and plant tolerance specifications.
Troubleshoot and repair mechanical failures on rotating equipment (bearings, seals, shafts, couplings) and static equipment by performing root-cause analysis, recommending corrective actions, and executing repairs to reduce downtime and repeat failures.
Conduct planned and emergency mechanical maintenance work, including disassembly/reassembly of complex machinery, removal and replacement of components, and requalification of equipment to meet safety and production requirements.
Read and interpret blueprints, mechanical schematics, wiring diagrams, hydraulic/pneumatic schematics, and OEM manuals to plan and execute installations, rebuilds, and maintenance tasks accurately.
Install, test, and commission new production lines and heavy equipment, coordinating with electrical, controls, and engineering teams to ensure safe, on-time startup and optimal machine performance.
Fabricate, weld, and modify metal components and support structures using MIG/TIG/arc welding and common fabrication tools to support custom repairs, retrofits, and on-the-fly machine adjustments.
Perform precision machining tasks including fitting, boring, grinding, and adapting components using lathes, mills, grinders, and portable machine tools to restore equipment to OEM tolerances.
Diagnose and repair hydraulic and pneumatic systems, including pumps, valves, cylinders, hoses, and fittings; test system pressures and flows and replace or rebuild components as required.
Execute scheduled preventive maintenance (PM) and predictive maintenance tasks—lubrication, alignment checks, belt and chain tensioning, filter changes, and condition monitoring—to improve mean time between failures (MTBF).
Maintain and document accurate maintenance records, job history, work orders, parts used, and service reports in CMMS systems (e.g., Maximo, SAP, Fiix) to support planning and continuous improvement.
Lead or participate in equipment turnarounds, shutdowns, and major overhauls, including scope development, task sequencing, and hands‑on execution to meet tight timelines and safety standards.
Install and maintain power transmission systems (gears, couplings, belts, chains, sprockets, bearings) and ensure correct torqueing, safety guarding, and alignment for reliable operation.
Perform field balancing and dynamic balancing of rotating machinery to reduce vibration and extend component life, using vibration analyzers and balancing equipment.
Collaborate with reliability engineering and operations to implement corrective action plans, failure mode effects analysis (FMEA), and continuous improvement projects to enhance equipment availability and reduce costs.
Use portable diagnostic tools (multimeter, clamp meter, thermal imager, vibration analyzer) to assist in multi-disciplinary troubleshooting and to identify electrical/mechanical interface issues.
Ensure all work is completed in strict compliance with lockout-tagout (LOTO), confined space entry, hot work, and other site safety procedures while promoting a safe culture among peers.
Train and mentor junior mechanics and apprentices on best practices for machine maintenance, safe rigging, alignment techniques, and use of precision tools and measurement standards.
Coordinate with vendors and contractors during specialized repairs or equipment installs, including providing technical direction, verifying work quality, and ensuring adherence to plant specifications.
Maintain an organized spare-parts inventory for critical assets, recommend stocking levels based on failure trends, and generate parts requests to minimize repair lead times.
Support continuous improvement by identifying recurring equipment issues, proposing redesigns or process changes, and participating in Kaizen or reliability improvement teams.
Perform material handling, rigging, and overhead crane operations safely to move heavy equipment and assemblies for maintenance or installation using proper slinging and rigging techniques.
Respond to after-hours mechanical emergencies and provide on-call support when required to restore production as quickly and safely as possible.
Ensure compliance with environmental and regulatory requirements related to maintenance activities (fluid containment, waste disposal, spill prevention) and complete required documentation.

Secondary Functions

Assist maintenance planning and storeroom teams with BOM validation, job scoping, and estimating labor and spare parts for complex maintenance tasks.
Contribute to asset health monitoring initiatives by collecting vibration, thermography, and oil analysis data and feeding results into the predictive maintenance program.
Support continuous training programs by preparing standard operating procedures (SOPs), maintenance checklists, and step-by-step repair guides for commonly serviced equipment.
Participate in cross-functional safety and reliability meetings, offering mechanical insight to production and engineering to optimize equipment uptime.
Help evaluate new tools and technologies (laser alignment systems, portable machining, bolting tools) to improve quality, speed, and safety of mechanical work.
