- Lead complex technical investigations related to electrical incidents, including root cause analyses, failure mode studies, and reliability assessments. Define, implement, and track corrective and preventive actions through to full resolution.
- Review and approve operational procedures (MOPs, SOPs, and EOPs), electrical switching plans, and high-risk energized work activities. Provide technical leadership during critical events, outages, major alarms, and abnormal operating conditions, while participating in the L3/L4 technical escalation rotation.
- Represent the engineering team during design reviews, commissioning activities, Integrated Systems Testing (IST), and operational handovers. Identify single points of failure, redundancy losses, and arc flash or short-circuit risks; maintain electrical documentation, single-line diagrams, and protection settings; mentor engineers; and establish regional electrical engineering technical standards.
