Core Responsibilities

Primary Functions

Execute and refine a comprehensive Preventive Maintenance (PM) program for all production machinery and facility equipment to proactively minimize breakdowns and extend asset lifespan.
Respond with a sense of urgency to unplanned equipment failures, applying advanced troubleshooting techniques to diagnose root causes across mechanical, electrical, pneumatic, and hydraulic systems.
Perform complex hands-on repairs and corrective maintenance on a wide array of industrial equipment, including CNC machines, PLCs, robotics, conveyors, and processing systems.
Lead or actively participate in Root Cause Analysis (RCA) investigations for significant downtime events, documenting findings and implementing corrective actions to prevent recurrence.
Manage the installation, commissioning, and qualification of new capital equipment, ensuring it meets performance specifications and integrates seamlessly into existing operations.
Uphold and enforce stringent safety standards, including Lock-Out/Tag-Out (LOTO) procedures, arc flash safety, and general OSHA compliance during all maintenance activities.
Read, interpret, and modify complex technical documentation, such as electrical schematics, mechanical blueprints, P&IDs, and equipment manuals, to facilitate effective troubleshooting and repairs.
Interface directly with equipment manufacturers and external service vendors to schedule specialized repairs, source technical information, and manage service contracts.
Develop and implement projects aimed at improving equipment reliability, increasing production efficiency, and reducing overall maintenance costs.
Troubleshoot and perform basic programming adjustments on Programmable Logic Controllers (PLCs), HMIs, and other industrial automation systems to resolve operational issues.
Utilize Computerized Maintenance Management Systems (CMMS) like SAP PM or Maximo to meticulously log work orders, track asset history, and manage spare parts inventory.
Conduct predictive maintenance activities, such as vibration analysis, thermal imaging, and oil analysis, to anticipate potential failures before they occur.
Design and fabricate custom parts, brackets, or machine guards using machine shop tools, welding equipment, and other fabrication techniques to support repairs and improvements.
Calibrate and maintain critical instrumentation and control devices to ensure they are providing accurate readings and functioning within specified tolerances.

Secondary Functions

Meticulously document all maintenance procedures, repair work, and equipment modifications to ensure an accurate and up-to-date knowledge base for the entire team.
Provide technical guidance, mentorship, and on-the-job training to maintenance technicians and machine operators to build a more skilled and self-sufficient workforce.
Assist the engineering and operations teams in the specification and selection of new or replacement equipment, providing input from a maintainability perspective.
Manage the inventory of critical spare parts, identifying reorder points, sourcing cost-effective suppliers, and ensuring parts are available to minimize repair times.
Champion continuous improvement initiatives, such as 5S, Lean Manufacturing, or TPM (Total Productive Maintenance), within the maintenance department and on the shop floor.
Participate actively in an on-call rotation schedule to provide after-hours and weekend support for critical equipment emergencies.
