Operations:

• Monitor the day-to-day performance of control systems, including BMS, EPMS, PLC/SCADA interfaces, metering, alarms, and related instrumentation.
• Support troubleshooting of control and instrumentation issues, including fault finding, root cause analysis, corrective actions, system recovery, and recurrence prevention.
• Review alarms, trends, logs, and system performance data to identify abnormalities, recurring faults, and improvement opportunities.
• Coordinate preventive and corrective maintenance with vendors and contractors, ensuring safe execution and accurate service records.
• Support incident response by reviewing event logs, analysing system behaviour, documenting findings, and following up on corrective actions.
• Maintain relevant operational procedures, alarm response guides, maintenance records, and control system documentation.
• Support controlled system changes, backup and recovery checks, user access reviews, patching coordination, and vulnerability remediation as required.
• Support control system asset lifecycle planning by monitoring spare parts availability, equipment condition, and potential technology obsolescence.

• Support FAT, SAT, testing, commissioning, system upgrades, and operational handover when required.
• Review relevant project documents, such as sequences of operation, alarm and points lists, O&M manuals, as-built drawings, and training materials.
• Highlight operational or handover gaps to the project team before systems are accepted into operations.
