Core Responsibilities

Primary Functions

Execute scheduled preventive maintenance tasks on mechanical assets (pumps, compressors, gearboxes, conveyors, mixers, turbines) according to PM schedules, checklists and manufacturer instructions to maximize uptime and extend equipment life.
Diagnose and repair mechanical failures in rotating equipment, including bearings, seals, couplings, shafts and gearboxes, using root cause analysis to prevent recurrence.
Perform precision shaft alignment (laser and dial indicator), belt/chain replacement and tensioning, and coupling installations to reduce vibration and extend component life.
Overhaul, disassemble, inspect, reassemble and test pumps, motors, gear reducers and compressors, documenting findings and recommending part replacements or design improvements.
Troubleshoot hydraulic and pneumatic systems—identify leaking valves, worn seals, cylinder failures, and pump issues—and repair or replace components to restore system performance.
Respond to unscheduled breakdowns and emergency repairs 24/7 as required, prioritizing safety protocols (lockout-tagout) and minimizing production downtime through rapid diagnosis and temporary or permanent fixes.
Use vibration analysis, thermography, ultrasonics and oil analysis data to identify early-stage mechanical faults, interpret results and implement corrective actions or schedule repairs.
Maintain and update accurate work orders, service logs and repair histories in the CMMS (e.g., Maximo, SAP PM, Infor) to support planning, spare parts management and reliability metrics.
Install and commission new mechanical equipment and production lines, including rigging, alignment, load testing and documentation of commissioning results.
Perform machining, fabrication and light welding tasks (MIG/TIG) to modify components, fabricate brackets, or repair housings and shafts when appropriate.
Implement and maintain lubrication programs—apply correct lubricants, maintain lube routes, and log lubricant consumption to prevent bearing and gearbox failure.
Calibrate and verify mechanical instrumentation and safety interlocks; ensure guards, sensors and emergency stops are functional and compliant with company and regulatory standards.
Coordinate material and spare parts procurement for planned downtimes and urgent repairs; maintain organized storeroom and recommend critical spares stocking levels based on failure modes and MTTR/MTBF analysis.
Support scheduled shutdowns, turnarounds and major overhauls by leading assigned mechanical scopes, developing task breakdowns, estimating labor and materials, and ensuring safe execution.
Collaborate with reliability engineers and production supervisors to drive continuous improvement projects (5S, Kaizen) aimed at reducing mean time between failures and maintenance costs.
Read and interpret mechanical drawings, P&IDs, schematics and BOMs to determine correct parts, tolerances and assembly procedures for repair and installation tasks.
Test, repair and verify variable frequency drives (VFD) mechanical interfaces, motor couplings and mounting integrity to ensure reliable motor-driven system performance.
Train and mentor junior technicians on safe repair practices, proper use of tools and diagnostic equipment, and company maintenance standards.
Enforce and promote safety best practices—including LOTO, confined space, PPE, and hazard communication—during maintenance and repair activities to maintain a zero-incident culture.
Document and escalate recurring failure patterns and propose design or process changes to reduce maintenance burden, including collaborating with vendors for corrective engineering actions.
Perform preventive and corrective maintenance on HVAC, refrigeration and auxiliary mechanical systems as required by facility scope.
Support cross-functional teams for root cause investigations, including collecting data, preparing failure reports, and participating in corrective action implementation and verification.
Maintain and inspect shop equipment (grinders, presses, hoists) and tools; schedule calibration and repairs to ensure readiness and safety for maintenance tasks.
Manage cost-conscious repair decisions—assess repair vs. replace options, prepare repair estimates and provide input on capital replacement planning.

Secondary Functions

Assist with maintaining spare parts inventory accuracy and cycle counts to minimize emergency procurement lead times.
Contribute hands-on support for reliability initiatives (vibration, thermography, oil sampling), and help prioritize findings into corrective maintenance actions.
Prepare clear maintenance reports and equipment condition summaries for production, engineering and management reviews.
Participate in pre-shutdown planning sessions, developing work scopes, labor estimates and risk assessments for mechanical scopes of work.
Support training programs by developing job aids, SOPs and maintenance checklists for recurring mechanical tasks.
Coordinate with external vendors and contractors for specialized repairs, ensuring work meets safety and quality standards.
Participate in continuous improvement teams to reduce downtime, streamline maintenance workflows, and reduce spare parts consumption.
Promote and follow company environmental, health and safety policies, and assist in incident investigations and corrective actions.
