- Improve network observability and reliability using monitoring, NetFlow, alerting, and incident response practices
- Support incident handling, post-incident reviews, documentation, and continuous improvement
- Work in line with change management, audit, compliance, and operational resilience requirements
- Collaborate closely with Security, Cloud Platform, Infrastructure, and Product teams
