Summary:

The Data Centre Specialist (DCS) is the most senior on-shift technical authority within the 24×7 Critical Operations team. This role provides deep technical expertise, operational assurance, leadership in incident response, and oversight of plant stability across all electrical, mechanical, controls and life-safety systems. The DCS ensures that all operational activities support STACK’s 100% uptime commitment by applying high-level technical judgement, disciplined risk management, real-time plant monitoring, and structured fault response. The role validates the quality of work completed by Senior Technicians and Technicians, enforces authorised operating boundaries, and ensures critical infrastructure is operated safely, accurately and consistently.

The DCS acts as a senior technical point of contact for the Critical Operations Supervisors and Senior Critical Operations Technicians, providing high-quality escalation context, analysis and operational recommendations. A concierge-level customer service approach is expected at all times when interacting with customers, visitors and stakeholders.

Responsibilities:

• Uphold STACK’s 100% uptime objective by providing advanced technical oversight, disciplined operational control and proactive plant monitoring.
• Maintain real‑time situational awareness of critical electrical, mechanical and controls systems, identifying weak signals, anomalies and developing risks through BMS/EPMS and field observations.
• Act as the senior technical escalation point for Senior Critical Operations Technicians and Critical Operations Technicians, providing real‑time guidance, diagnostic support and risk evaluation.
• Lead or support first‑response incident actions, including stabilisation, containment decisions, technical communication and event documentation.
• Perform advanced diagnostics on abnormal conditions, including interpretation of telemetry, protection responses, redundancy shifts and thermal behaviours.
• Verify operational readiness following maintenance, resets, system changes or commissioning activities by confirming alarms, redundancy status, load paths and control sequences.
• Provide technical direction during planned maintenance, shutdowns, functional testing and energisations to ensure safe execution aligned to SOPs/MOPs/EOPs.
• Conduct targeted enhanced rounds focusing on redundancy health, automation behaviour, generator/UPS coordination, thermal stability and plant performance.
• Coordinate vendor activities during shift, ensuring safe execution, alignment to site requirements and correct system configuration post‑maintenance.
• Identify systemic risks, recurring faults, capacity constraints and design issues; escalate to Supervisors, Site Director and engineering stakeholders.

Qualifications and preferred Education & Experience:

• Advanced operational judgement in a mission‑critical environment.
• Strong technical capability in electrical, mechanical and controls systems.
• Expert interpretation of plant telemetry, protection behaviour, automation sequences and redundancy models.
• Structured troubleshooting and stabilisation capability under pressure.
• Proficiency with BMS/EPMS, CMMS and operational data platforms.
• Calm, authoritative presence during alarms, escalations and operational events.
• Strong coordination and oversight skills for work control, vendor interaction and RTS verification.
• Extensive experience in data centres or other mission‑critical facilities (utilities, hospitals, defence, industrial).
• Demonstrated expertise operating and monitoring critical power and cooling systems (UPS, generators, switchgear, PDUs/PMMs, ATS/STS, CRAC/CRAH, FWU/CDU, chilled water systems, pumps, controls, fire systems).
• Experience reviewing MOPs, SOPs, EOPs, risk assessments, switching plans and commissioning documentation.

Work Environment/Conditions:

• Role supports a 24×7 rotating shift environment, including nights, weekends and public holidays as operationally required.
• Work occurs across data halls, plant rooms, electrical/mechanical spaces and external plant areas; PPE required under site policy.
• Participation in emergency response, readiness exercises and incident management activities is required.

Work Authorization/Security Clearance Requirements

• Legal entitlement to work in Australia.
• Ability to satisfy pre-employment screening requirements (as applicable), including right-to-work checks, background checks and reference checks.
• Ability to meet data centre security requirements including badging, access control and adherence to customer-mandated security protocols.
• Security clearance is not required unless specified for a customer-specific facility.
