The position reports to the Senior Maintenance Manager.

Reliability Analysis & Asset Lifecycle Planning

• Build and maintain the Criticality Analysis plus Critical Spare Parts assessments for all production equipment.
• Develop and maintain an equipment replacement/repair roadmap driven by reliability data, asset age, and lifecycle cost analysis.
• Calculate equipment reliability metrics (MTTR, MTBF, etc.) and perform root cause failure analyses (RCFA) to identify failure patterns, prioritize maintenance resources, and reduce unplanned downtime.
• Build Reliability Block Diagrams (RBD) for critical systems to assess single-point-of-failure risks and model overall system availability (OEE).

Factory Floor Technical Support – Provide SME technical support for key production systems (chemical addition, batch-making, product filling, ultra-pure water, hot oil, process chillers, wastewater, etc.), ensuring uptime and optimal performance. Identify opportunities and run associated projects to improve overall system design.
