Summary/Objective
The Maintenance Systems & Planning Coordinator supports the safe, compliant and reliable operation of STACK’s mission-critical infrastructure by administering the Computerised Maintenance Management System (CMMS), coordinating maintenance schedules, and governing the change management workflow. This role chairs the weekly Change Advisory Board (CAB) to ensure disciplined process execution, while technical approvals remain with the ACOM and COM. The position ensures no conflicting maintenance activities occur across mechanical, electrical, controls and supporting systems and prevents excessive change stacking on the same day. The Coordinator also administers the rotating shift roster, annual/sick leave entries, and relief coverage planning to maintain continuous staffing for 24/7 operations. This role directly contributes to STACK’s 100% uptime commitment and our expectation of concierge-level customer service.
