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, adaptable 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

STACK is seeking an experienced Critical Operations Director to establish and lead the Operations function for its Melbourne data centre campus. Reporting to the VP Critical Operations (Aust), this role has end-to-end accountability for site safety, operational readiness, reliability, customer service and the performance of all mission-critical mechanical, electrical, plumbing, fire life safety, controls and base-building systems.

This is a senior people leadership role for a proven leader who has successfully managed 100+ employees, including managers, supervisors and frontline technical teams. The Director will recruit, develop and lead the Operations team, work collaboratively across STACK, build trusted customer relationships and create an inclusive, accountable and high-performing culture. All Critical Operations staff report through this role.

Candidates may come from data centres or other complex mission-critical environments, including Defence, naval operations, aviation, utilities, power generation, transport, healthcare or large-scale industrial operations. Direct data-centre experience is advantageous but is not essential where the candidate can demonstrate leadership of large technical workforces, operational readiness, asset reliability and incident command in a high-consequence 24/7 workplace.

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.
