Core Responsibilities

Primary Functions

Conduct comprehensive preventive maintenance inspections and scheduled service on pumps, conveyors, motors, gearboxes, presses, packaging equipment and other plant machinery to maximize uptime and extend equipment life.
Diagnose, troubleshoot and repair mechanical failures using precision hand tools, power tools, alignment equipment and diagnostic meters to restore production quickly and safely.
Troubleshoot and program PLCs, HMIs and industrial control systems (Allen‑Bradley, Siemens, Mitsubishi or equivalent), modifying ladder logic and parameter settings to correct control and sequencing faults.
Perform electrical diagnostics and repairs on control panels and power distribution systems, including wiring repairs, contactor replacement, relay troubleshooting and capacitor/motor starter servicing up to 480VAC.
Execute predictive maintenance tasks such as vibration analysis, infrared thermography, oil analysis and laser alignment to identify early signs of wear and prevent catastrophic failures.
Replace and align rotating equipment (motors, gearboxes, couplings), perform motor mounts and shaft alignments, and balance assemblies to reduce vibration and increase bearing life.
Install, commission and validate new production equipment and retrofits, coordinating with OEMs, vendors and engineering to ensure proper integration and documentation.
Troubleshoot and repair pneumatic and hydraulic systems (valves, cylinders, pumps, filters), identify leaks, replace seals and maintain system pressure to specification.
Respond to equipment breakdowns and production line stoppages with urgency, using structured troubleshooting methodologies to get lines running with minimal downtime.
Maintain detailed maintenance records, work orders and equipment histories using a CMMS (SAP, Maximo, UpKeep, Fiix or similar), ensuring accurate parts usage, labor hours and root cause documentation.
Lead or participate in root cause analysis (5 Whys, Ishikawa diagrams) and implement corrective actions to prevent recurrence of chronic equipment issues.
Stock and manage critical spare parts, coordinate procurement with storeroom and suppliers, and suggest inventory optimization to reduce lead times for repairs.
Implement and enforce lockout/tagout, confined space, electrical safety and other site-specific safety procedures; participate in safety audits and hazard analyses.
Perform welding, brazing, fabrication and basic machining tasks to repair frames, guards and custom fixtures in support of production needs.
Calibrate sensors, flow meters, scales and process instrumentation to ensure process accuracy and regulatory compliance.
Adjust mechanical drives, tensioning devices and packaging changeover components to optimize throughput and reduce scrap during product changeovers.
Train production staff on basic equipment troubleshooting, daily inspections and safe operating practices to reduce preventable breakdowns.
Participate in continuous improvement projects (Kaizen, 5S, TPM) to increase overall equipment effectiveness (OEE) and reduce maintenance costs.
Support commissioning, validation and qualification activities for regulated products (if applicable), maintaining traceable documentation for audits.
Assist engineering with design-for-maintainability recommendations, retrofit proposals and capital project implementation to improve long-term reliability.
Maintain clear communication with production leads, engineers and management during planned outages, turnarounds and maintenance windows to coordinate work and minimize impact.
Participate in on-call rotations and flexible shifts as needed to support 24/7 operations and emergency response.
Perform periodic housekeeping, guard and machine safety checks, and report any non-conforming conditions that may impact employee safety or product quality.
Drive continuous learning by staying current with industry best practices, control system upgrades and new maintenance technologies (e.g., IIoT predictive tools).

Secondary Functions

Support production during line startups, changeovers and scheduled product launches by providing technical assistance and quick repairs.
Assist the maintenance planner and procurement team with generating parts lists, estimating repair times and verifying vendor documentation and warranties.
Contribute to the facility’s maintenance strategy, preventive maintenance schedule and predictive analytics roadmap to prioritize high-impact assets.
Collaborate with engineering, quality and production to translate failure modes into engineering changes or process adjustments.
Participate in shift handovers and maintain clear shift logs to ensure continuity of knowledge and minimize repeat troubleshooting.
Document lessons learned from major failures and update standard operating procedures (SOPs) and maintenance checklists.
Help run pilot projects that evaluate new maintenance technologies, spare-part optimization software or sensors for condition monitoring.
