* Monitor temperatures, pressures, flow rates and water quality through BMS, DCIM and local controls.
* Carry out planned preventative maintenance (PPM), inspections and mechanical servicing.
* Diagnose and respond to cooling faults, leaks, pump failures and system alarms.
* Carry out water sampling, testing and support chemical treatment.
* Follow emergency procedures to restore cooling and protect critical IT equipment.
* Complete shift handovers, maintenance records, permits and incident reports.
* Work in accordance with RAMS, MOPs, SOPs, EOPs and safe isolation procedures.
* Supervise specialist contractors and OEM engineers, supporting commissioning, fault investigations and system improvements.
Essential Qualifications & Experience
* Experience working in mission-critical facilities and data centre cooling environments.
* Strong knowledge of chilled water and closed-loop cooling systems.
* Experience maintaining pumps, valves, actuators, heat exchangers and filtration systems.
* Knowledge of water treatment, leak detection and water quality management.
* Experience using BMS systems for monitoring, alarms and fault diagnosis.
* Understanding of Permit-to-Work systems and safe working procedures.
* Experience responding to mechanical emergencies in live operational environments.
Desirable Experience
* Direct-to-chip liquid cooling and CDU systems.
* AI and high-performance computing (HPC) data centres.
* Liquid cooling equipment from Schneider, Vertiv, CoolIT, Motivair, Stulz or equivalent.
* Experience in Tier III or Tier IV data centres.
* Critical Facilities Management and 24/7 engineering operations.
Key Skills
The successful candidate will be confident fault-finding on mechanical cooling systems, able to respond effectively to critical incidents and comfortable working independently as part of a rotating shift team. Good communication, accurate reporting and a strong understanding of health and safety are essential.
