Core Responsibilities

Primary Functions

Execute predictive maintenance (PdM) tasks, including collecting and analyzing data from vibration analysis, infrared thermography, oil analysis, and ultrasonic testing to assess equipment health.
Perform root cause analysis (RCA) on equipment failures and chronic issues to identify fundamental causes and develop effective, lasting corrective actions.
Utilize and maintain a Computerized Maintenance Management System (CMMS) to document work orders, track asset history, manage condition-monitoring data, and report on key performance indicators.
Conduct precision mechanical tasks, including laser alignment of rotating equipment shafts and dynamic balancing of components like fans and rotors to minimize vibration and wear.
Develop and optimize preventive maintenance (PM) procedures and schedules based on failure data, equipment criticality, and reliability-centered maintenance (RCM) principles.
Calibrate, operate, and maintain a wide array of sophisticated diagnostic tools and test equipment used for condition monitoring and troubleshooting.
Interpret complex technical documentation, including P&IDs, electrical schematics, mechanical blueprints, and OEM manuals, to support maintenance and troubleshooting activities.
Lead or actively participate in Failure Mode and Effects Analysis (FMEA) to proactively identify potential failure modes and implement mitigation strategies.
Monitor critical equipment parameters and performance trends, generating detailed reports and recommendations for the engineering and management teams.
Provide expert technical guidance and hands-on training to other maintenance technicians on reliability best practices, precision maintenance techniques, and new technologies.
Install and commission new and repaired equipment, ensuring it meets all operational specifications and reliability standards before being returned to service.
Conduct various non-destructive testing (NDT) methods, such as dye penetrant, magnetic particle, or ultrasonic thickness testing, to inspect for component defects.
Collaborate closely with operations and engineering departments to provide reliability-focused input on equipment modifications, upgrades, and new capital projects.
Manage and document the lubrication program, ensuring correct lubricants, application methods, and frequencies are used for all plant machinery.
Adhere to and champion all site safety protocols and procedures, including Lockout/Tagout (LOTO), confined space entry, and hot work, ensuring a safe work environment.
Investigate equipment performance issues by collecting and analyzing operational data to identify subtle changes that may indicate impending failure.

Secondary Functions

Support capital project teams by providing reliability input during the design, procurement, and commissioning phases of new equipment installations.
Assist in the management of the critical spare parts inventory, providing recommendations on stocking levels and component specifications.
Champion a site-wide culture of reliability and proactive maintenance by engaging with operators and other stakeholders.
Participate in continuous improvement initiatives, such as Kaizen events, focused on enhancing maintenance processes and overall plant efficiency.
