Services Manager/Engineer - Mechanical (Australia)

The Services Manager/Engineer - Mechanical is the client-side technical and delivery lead for mechanical and hydraulic services on hyperscale and mission-critical data-centre projects. The role provides senior leadership from concept and design through procurement, manufacture, construction, commissioning and handover, ensuring the cooling and hydraulic infrastructure achieves the required capacity, resilience, maintainability, energy performance and programme outcomes.

The position requires proven data-centre experience and the ability to lead multi-disciplinary teams, engage credibly with designers, contractors and OEMs, and make sound technical and commercial decisions. A core focus is the integration of air-cooled chiller systems, liquid-cooled racks, hydraulic services and associated heat-rejection, distribution, controls and monitoring infrastructure, including phased deployment in live or operationally sensitive environments.

The role also leads the client interface for modular and off-site construction, including prefabricated plantrooms, skids, containerised systems and factory-tested assemblies. It establishes the assurance regime from factory acceptance through site integration and integrated systems testing.

Key responsibilities

- Lead the mechanical-services workstream on behalf of the client, setting technical priorities, delivery expectations, reporting and assurance activities.
- Coordinate designers, principal contractors, specialist mechanical contractors, OEMs, commissioning providers and internal delivery, operations and commercial teams.
- Provide clear advice on technical risk, programme, cost, constructability, resilience and operational impacts; escape material issues with practical recommendations.
- Promote a safety-first culture across design, factory and site activities, including safe commissioning and transition to operations.




- Assist reviews of basis of design, drawings, specifications, calculations, equipment selections and design changes for critical cooling and hydraulic systems.
- Provide technical assurance for air-cooled chiller systems, chilled-water distribution, pumps, heat exchangers, CRAH/CRAC equipment, ventilation, water treatment, hydraulic services, in-ground services, drainage, leak detection and BMS/DCIM interfaces.
- Lead the mechanical integration strategy for liquid-cooled racks, including CDU architecture, secondary-loop distribution, water quality, containment, leak detection, controls, redundancy, maintainability and staged capacity deployment.
- Lead technical evaluation of mechanical and controls tender submissions, identifying scope gaps, qualifications, programme risks and departures from requirements.
- Lead the client-side approach to modular construction for mechanical infrastructure, including prefabricated plantrooms, skids, pipe-rack modules and factory-integrated controls systems.
- Review contractor methodologies, inspection and test plans, quality records, commissioning plans and completion documentation.
