Core Responsibilities

Primary Functions

Lead, mentor, and supervise a team of maintenance mechanics: assign daily work, set performance expectations, conduct regular coaching and development, and perform performance reviews to build a high-performing maintenance organization focused on safety and uptime.
Oversee and execute preventive maintenance (PM) and predictive maintenance (PdM) programs across mechanical, electrical, pneumatic, and hydraulic systems to maximize equipment reliability and lifecycle.
Direct troubleshooting and repair of complex mechanical and electrical failures, including motors, gearboxes, conveyors, pumps, compressors, HVAC systems, and automated production equipment.
Manage the CMMS workflow: create, prioritize, assign, and close work orders; enforce time and material tracking; maintain accurate asset history for reliability analysis and continuous improvement.
Supervise and perform PLC and control system troubleshooting and minor programming adjustments in coordination with controls engineers to minimize production interruptions.
Implement maintenance strategies for minimizing downtime—root cause analysis (5 Whys, RCA), corrective action plans, and verification of repairs to prevent repeat failures.
Develop and maintain spare parts inventory strategy and BOMs: forecast critical spares, control inventory levels, and coordinate purchasing to ensure parts availability while minimizing carrying costs.
Create daily and weekly shift schedules, coordinate on-call rotations, and ensure 24/7 coverage for critical plant systems while optimizing labor utilization and overtime.
Enforce and coach team on safety programs and regulatory compliance: Lockout/Tagout (LOTO), confined space entry, PPE requirements, OSHA standards, and facility-specific safety rules.
Lead and coordinate major planned maintenance outages and shutdowns, including scope definition, resource allocation, contractor management, and post-outage documentation and lessons learned.
Manage relationships and contracts with vendors and service providers for specialized repairs, calibration, and inspections; ensure vendor compliance with site safety and quality standards.
Drive continuous improvement and Lean initiatives (5S, Kaizen) within the maintenance group to reduce waste, improve response time, and increase first-time-fix rates.
Prepare, manage, and report on the maintenance area budget: labor, overtime, parts, and contracted services; identify cost-saving opportunities and justify capital expense requests.
Maintain accurate technical documentation, maintenance procedures, SOPs, electrical/mechanical prints, and change logs for audit readiness and knowledge retention.
Ensure calibration and preventative schedules for instrumentation and safety-critical devices are maintained and documented to comply with quality and regulatory requirements.
Conduct skills assessments, identify training needs, and deliver hands-on technical training and cross-training to expand team capability and redundancy.
Coordinate machine installations, relocations, and modifications with engineering and production teams, ensuring mechanical integrity, alignment, and code compliance.
Implement predictive maintenance technologies (vibration analysis, thermal imaging, ultrasound) and partner with reliability teams to convert condition data into actionable work orders.
Monitor and report maintenance KPIs: mean time between failures (MTBF), mean time to repair (MTTR), preventive maintenance compliance, backlog, and cost per unit metrics; use data to drive decision-making.
Respond to emergency breakdowns and safety incidents: lead troubleshooting, containment, and rapid repair while documenting root causes and corrective actions to prevent recurrence.
Enforce high standards of housekeeping and environmental controls in mechanical rooms and maintenance shops, including hazardous materials handling and disposal.
Participate in product changeovers and new product introductions to ensure equipment readiness, minimizing ramp-up issues and quality losses.

Secondary Functions

Support continuous improvement projects by contributing maintenance expertise to cross-functional teams focused on throughput, quality, and safety.
Assist in the development and rollout of digital maintenance initiatives, such as CMMS upgrades, work order automation, and equipment performance dashboards.
Conduct periodic audits of maintenance processes, spare parts stores, and contractor performance to identify gaps and drive corrective actions.
Provide technical input to capital expenditure (CapEx) proposals by estimating labor and parts requirements, ROI, and reliability benefits.
Participate in plant leadership meetings to align maintenance objectives with production targets, safety goals, and overall business priorities.
Facilitate apprentice and trade-school partnerships to attract, develop, and retain skilled maintenance technicians for future staffing needs.
