COMPANY OVERVIEW
STACK Infrastructure builds, owns, and operates hyperscale and colocation data centers that power the world’s most ambitious technology companies. With a rapidly expanding footprint across APAC, STACK combines deep development expertise, flexible capital, and operational discipline to deliver critical digital infrastructure at scale.
Our clients include the largest hyperscale cloud platforms. We are building a regional platform defined by speed of delivery, power reliability, and long-term partnership — and we are assembling the team to lead that effort.
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 supports STACK’s commitment to 100% uptime and a concierge-level customer service experience, ensuring risk is proactively managed, planned works are executed safely, and customer communications are clear, timely and professional.

Reasonable accommodations may be made to enable individuals with disabilities to perform these essential functions.
Critical Operations
• Uphold STACK’s 100% uptime objective by maintaining accurate, reliable CMMS data to support operational decision-making.

• Track deferred changes, overdue actions, incomplete close-outs and escalate procedural non-compliance to the CFM.
• Support vendor scheduling by ensuring all works are accurately recorded, do not conflict with site operations and include required compliance documentation.
• Maintain audit-ready CMMS and change documentation for internal reviews, customer audits and regulatory requirements.
• Develop and issue weekly/monthly reporting: PPM compliance, overdue work orders, change volumes, risk categories, conflict flags, and CAB action closure.

• Experience administering CMMS/EAM systems and coordinating maintenance or change schedules.
• Familiarity with operational change management workflows (CAB, MOP/SOP/ITP, PIR).
• Exposure to technical systems (electrical, mechanical, HVAC or controls) is desirable but not essential. Engineering or trade background preferred but not essential.
• Understanding of rostering, Award considerations and staffing coverage models for 24/7 operations.
Additional Eligibility Requirements
