• Support continuous improvement by identifying incident trends, participating in post-incident reviews (PIRs), and helping evolve monitoring rules and automation alerts.
• Produce and maintain clear technical documentation, including runbooks, fault handling procedures, and change logs.
• Adhere to and contribute to operational KPIs such as Mean Time to Restore (MTTR), SLA compliance, and incident response targets.
• Assist in the training and onboarding of new team members as required.
