Act as a key custodian of the sites Maintenance, MI program and contractor management, embedding robust engineering standards and disciplined execution across maintenance and projects. The role requires strong leadership and people skills. Job Responsibilities Maintenance & Reliability Leadership Own the site maintenance strategy (preventive, predictive, and corrective), aligned with COMAH safety requirements and plant criticality. Maintain mechanical, electrical, instrumentation, and control assets to achieve high availability and integrity-especially for high-hazard equipment (e.g., reactors, storage tanks, formaldehyde handling systems). Implement reliability-centred maintenance (RCM), failure mode & effects analysis (FMEA), and defect elimination to reduce unplanned downtime. Establish and manage spares strategy and obsolescence plans for critical equipment. Drive improvement and compliance with Bakelite EU Maintenance & Reliability KPI’s for the site. Champion CMMS usage (work management, backlog control, planning & scheduling, KPI reporting). Management of mechanical integrity programs (thickness surveys, NDT, inspections, calibration/testing of relief devices). Safety & COMAH Compliance Ensure maintenance and project work protects the Safety Report assumptions and Safety Instrumented Functions (SIFs) integrity. Involvement with PHA (HAZOP/LOPA). Support Permit-to-Work systems (isolation, line-breaking, hot work, confined space, excavation) and control of ignition sources. COMAH Duty Manager on call rotation Project Management (CAPEX/OPEX) Assist with delivering the site’s CAPEX portfolio from concept to handover: scope, feasibility, on site management and commissioning. Involvement with Management of Change (MoC) for equipment, process, controls, and documentation changes and pre-startup safety reviews (PSSR). Manage contractors/vendors: pre-qualification, competence assessment, RAMS review, site induction, supervision, and performance. Manage contractors to construct and commission based on "issued for construction" designs in collaboration with the Project Manager Where necessary and in accordance with agreed processes, ensure design alignment with corporate engineering standards, best available techniques, and lifecycle cost/maintainability. People, Culture & Stakeholder Management Lead and develop multi-disciplinary maintenance team Build strong interfaces with Operations, EHS, Quality, Supply Chain, and Corporate Engineering. Promote a positive culture and speak-up environment for safety; lead incident investigations. Communicate plans, and risks clearly to leadership and regulators where appropriate. Continuous Improvement Implement continuous improvement in maintenance and shutdown execution. Utilise condition monitoring, vibration analysis, thermography, online diagnostics, and data analytics to improve reliability. Optimise energy usage and emissions performance (aligned to ISO 50001 where applicable).
