Operations

Lead and embed a safety-first culture across all mechanical activities, including permit-to-work, isolations/LOTO for mechanical systems, SWMS and method statement compliance.
Oversee the operation, maintenance and repair of mission-critical mechanical infrastructure supporting 24/7 operations: chilled water systems (chillers, CDUs, heat exchangers, headers, valves, differential pressure control); cooling towers (water chemistry, basin management, fan and drive systems); pumps and VFDs, strainers and balancing valves; CRAH/CRAC units and close-coupled/row/door coolers; CDU and liquid-cooling distribution for high-density workloads; dehumidification/humidification, leak detection and environmental monitoring; and fire life safety interfaces (mechanical shutdowns, smoke control).
Set and uphold mechanical maintenance standards and schedules; ensure PMs are completed on time, to scope and with quality evidence.
Review and approve MOPs, SOPs, EOPs and sequences of operation; ensure risk assessments, hold points and rollback steps are defined and executable.
Direct and quality-assure testing programs (functional checks, flow/pressure verification, valve stroke, vibration, thermography for rotating equipment, water treatment compliance) and address findings with corrective actions.
Use BMS/DCIM and analytics to monitor plant performance, identify anomalies, manage alarms, conduct trend reviews and verify efficiency and stability after changes.
Provide technical leadership during incidents affecting mechanical systems; coordinate triage, stabilisation, root cause analysis, and corrective/preventative action close-out.
Plan and coordinate minor/medium works, upgrades and lifecycle replacements; manage change control, outage windows and customer impact mitigation.
Validate and maintain mechanical documentation: P&IDs, as-builts, valve lists, setpoint schedules, sequences and commissioning records.
Drive optimisation initiatives to improve reliability, resilience and efficiency (e.g., chiller setpoint strategies, condenser water optimisation, economiser strategies where applicable).
