Core Responsibilities

Primary Functions

Lead, schedule and mentor a team of mechanical technicians, assigning daily work, coaching for skill development, conducting performance reviews, and ensuring adherence to company policies and safety procedures.
Develop, maintain and optimize preventive maintenance (PM) schedules in the CMMS (e.g., IBM Maximo, SAP PM, Infor, eMaint) to increase equipment uptime and reduce emergency repairs.
Supervise and participate in troubleshooting and repair of mechanical systems including pumps, compressors, gearboxes, bearings, conveyors, roll stands, mixers, and related rotating equipment, ensuring repairs are executed safely, correctly and efficiently.
Implement and manage predictive maintenance programs (vibration analysis, thermography, oil analysis, laser alignment) and use findings to prioritize repairs and capital replacements that improve reliability.
Perform and lead root cause analysis (RCA) and corrective action processes for repeat failures, documenting findings, establishing corrective controls and tracking closure through the CMMS.
Coordinate machine rebuilds, overhauls and major mechanical projects—planning scope, procuring parts, scheduling technicians and contractors, and validating post-repair performance against KPI targets.
Enforce machine guarding, lockout/tagout (LOTO), confined space, and other safety policies; lead safety audits, near-miss investigations and corrective action implementation to maintain a safe work environment.
Manage mechanical spare parts inventory and critical spares strategy: define MRO stock levels, approve reorder points, control storage, and collaborate with procurement to reduce lead times and forecast needs.
Develop maintenance KPIs (MTBF, MTTR, availability, PM compliance) and deliver regular reports to operations and plant leadership, using data to drive reliability improvements and budget decisions.
Inspect and maintain piping systems, valves, steam traps, hydraulic and pneumatic circuits, ensuring integrity and minimizing leaks, pressure losses, or contamination risks.
Troubleshoot and maintain hydraulic and pneumatic systems—diagnosing seal failures, cylinder leaks, pump issues, pressure losses and performing component replacements and system testing.
Supervise contractor and vendor work for mechanical installations, lift plans and specialty repairs; ensure vendor compliance with safety and quality standards and validate workmanship at handover.
Coordinate shutdowns and planned outages: create detailed work scopes, assign crews, manage materials and tool staging, and lead post-shutdown performance validation.
Oversee calibration and validation of mechanical gauges, torque tools, and maintenance test equipment to ensure accuracy and compliance with QA requirements.
Ensure mechanical designs, modifications and retrofits are executed following engineering drawings, OEM recommendations, and change control procedures; produce and maintain installation documentation.
Lead continuous improvement initiatives such as TPM, 5S, Kaizen events or reliability-centered maintenance projects to reduce waste, lower maintenance costs and improve machine uptime.
Support production changeovers and new equipment commissioning by planning mechanical workstreams, addressing design-for-maintainability issues and training operators on basic mechanical care.
Maintain compliance with local, state and federal regulations and standards (OSHA, NFPA, API, ASME where applicable) for mechanical equipment and pressure vessels.
Manage maintenance budget line items for mechanical repairs, spare parts and contractor services; review cost trends, justify expenditures and propose CAPEX for equipment upgrades based on ROI and reliability risk.
Develop and deliver structured technical training programs for mechanical skills (bearing replacement, alignment, shaft repair, pump overhaul, welding basics) and ensure competency validation of technicians.
Create and maintain accurate maintenance documentation—including PM procedures, mechanical standard work, failure mode libraries, BOMs and equipment history—to support knowledge transfer and continuous improvement.
Respond to emergency breakdowns and large-scale mechanical failures, leading the triage process, resource allocation, and rapid restoration of critical equipment minimizing production impact.

Secondary Functions

Collaborate with engineering and operations to support capital projects, plant expansions and equipment modifications from design through handover.
Participate in cross-functional reliability and safety committees to align maintenance goals with production, quality and EHS objectives.
Support vendor evaluation and selection for mechanical services and equipment, including scope review, capability assessment and contract administration.
Lead efforts to digitize maintenance workflows (CMMS enhancements, mobile work orders, data collection for analytics) to improve responsiveness and data visibility.
Assist in developing multi-trade maintenance strategies and coordinate with electrical, instrumentation, and controls groups for integrated troubleshooting.
Provide technical input for the development of SOPs and production maintenance checklists to empower operators and reduce reactive repairs.
Help manage environmental compliance for mechanical systems (e.g., oil containment, leak detection, emissions equipment maintenance) and support related audits.
Serve as escalation point for complex mechanical issues outside routine scope, providing subject-matter expertise and field leadership during incidents.
