Key Responsibilities

1. Containerization

- Containerize existing .NET applications (currently Windows-hosted) using both Windows containers and Linux containers where feasible, evaluating migration paths from .NET Framework to modern .NET where applicable
- Build and maintain Dockerfiles, multi-stage builds, and image optimization for size and security
- Establish a private container registry (Quay, Harbor, or OpenShift's internal registry) with image scanning and vulnerability management

2. Local / Office Test Environment

- Set up an on-prem lab environment (Docker/Podman + a lightweight Kubernetes distro such as k3s/RKE2, or OpenShift Local/CRC) to validate containers before promotion
- Own the full inner-loop test cycle: build → scan → run → validate → push

3. Enterprise OpenShift Deployment

- Design and deploy Red Hat OpenShift Container Platform (OCP) in the data center — cluster sizing, node roles (control plane / infra / worker), storage (ODF or Nutanix CSI), and networking (SDN/OVN-Kubernetes)
- Own OpenShift lifecycle management: upgrades, operators, RBAC, namespaces/projects, resource quotas
- Integrate the cluster with existing Nutanix HCI infrastructure

4. CI/CD & Environment Promotion

- Build CI/CD pipelines (Jenkins, GitLab CI, Tekton, or Azure DevOps) to move images from build through Dev, UAT, and Production
- Define and enforce environment-specific configuration (ConfigMaps/Secrets,



Vault/OpenBao integration)
- Set up UAT and Production namespaces/clusters with appropriate isolation, approval gates, and change control — important given the BFSI compliance context

5. Operations & Reliability

- Implement monitoring and logging (Prometheus, Grafana, EFK/Loki) and alerting for containerized workloads
- Own backup/DR strategy for stateful workloads running on OpenShift
- Perform capacity planning and cost/resource optimization across clusters

Required Skills

- 3+ years hands-on with Docker/Podman and Kubernetes (OpenShift preferred, or GKE/AKS/EKS with willingness to specialize in OpenShift)
- Experience containerizing .NET applications, including Windows container nuances
- Solid Linux fundamentals (RHEL preferred, given the OpenShift/Red Hat ecosystem)
- CI/CD pipeline design and scripting (Bash/PowerShell/Python)
- Networking fundamentals: ingress/routes, load balancing, and basic service mesh concepts
- Familiarity with secrets management, RBAC, and image security scanning

Preferred / Nice-to-Have

- Red Hat certifications (RHCSA, EX280 – OpenShift Administration)
- Experience in BFSI/regulated environments (audit trails, change management, data residency)
- Experience with Nutanix HCI or other on-prem virtualization
- Exposure to service mesh (Istio/OpenShift Service Mesh) and GitOps (ArgoCD/OpenShift GitOps)
