Responsibilities

End-to-end administration and operations of CNIS platforms, including Kubernetes, container runtimes, and cloud-native infrastructure components. Manage and optimize the Cloud Container Distribution (CCD) by overseeing provisioning, upgrades, backup/restore, lifecycle management, and disaster recovery readiness. Perform CCD health checks, configuration drift analysis, capacity tracking and environment validation across clusters. Work closely with application and platform teams to onboard workloads and provide CCD-level support.

Monitor system performance and availability using tools such as Prometheus, Grafana and other observability platforms. Maintain detailed runbooks, MOPs and CNIS documentation to ensure operational readiness. Define and govern CNIS architecture, platform standards, and design principles for Kubernetes-based environments. Lead design reviews, capacity planning and platform lifecycle strategies covering deployment, upgrades, backup/restore, disaster recovery and decommissioning. Establish multi-cluster architecture, workload placement strategies and platform segmentation models. Drive adoption of Infrastructure-as-Code (IaC), GitOps and automation frameworks. Define observability architecture and lead platform modernization and transformation initiatives. Lead disaster recovery planning, execution and root cause analysis of major incidents.
