Senior Manager Cloud Development

The Role

The Senior Manager of Container Orchestration Services leads the design, delivery, and continuous improvement of Lumen’s Rancher as a Service (RaaS) platform as a clearly defined Managed IT Service that advances service transformation across multi-cloud environments. 

This leader is responsible for managing a high-performing team of Kubernetes platform engineers who operate and scale a large enterprise Rancher environment spanning AWS (EKS), Azure (AKS), GCP (GKE), and on-prem clusters. 

The role focuses on transforming Kubernetes operations from fragmented platform support into a standardized, secure, automated, and customer-centered service model. This includes defining service capabilities, service levels, intake pathways, consumption patterns, and measurable outcomes that enable application teams to deploy and operate workloads at scale through self-service while maintaining operational excellence, governance, and reliability.
