• Lead post-handover lessons-learned meetings to support continuous improvement.
• Review the operational performance of electrical infrastructure and provide regular stakeholder updates.
• Work with the training department to develop the technical capability of regional personnel.
• Undertake project management duties, including planning, costing, procurement, subcontractor selection, supervision and delivery.
• Participate in the regional call-out and escalation team when required.
