In this end-to-end technical role, you will takefull ownership of the platform lifecycle - facilitating design workshops,building GitOps-driven architectures, driving application onboarding, andexecuting greenfield deployments from scratch in a highly regulatedenvironment. Key Responsibilities End-to-End Execution Driveall technical deliverables across the full project lifecycle, from initialconcept and High-Level Design (HLD) / Low-Level Design (LLD) to hands-on buildand infrastructure implementation. Greenfield OCP Deployment Deploy, configure, and validate on-premises Red Hat OpenShift ContainerPlatform clusters from scratch across multiple client environments. Application Onboarding & TeamEngagement Actively engage with platform engineering andapplication teams to establish onboarding patterns, developer workflows, andmigration strategies to successfully onboard applications onto the platform. Advanced On-Premises Container Networking Architect and implement enterprise container networking architectures,including OVN-Kubernetes , User-Defined Networks (UDN) , MultusCNI (for multi-network Pod interfaces), NMState / NNCP for host nodenetworking, MetalLB / BGP for on-prem load balancing, Ingress/Egressrouting, and Service Mesh ( Istio / Red Hat OpenShift Service Mesh ). GitOps & Continuous Delivery Implement GitOps practices using Argo CD / OpenShift GitOps forautomated, version-controlled cluster provisioning, configuration management,and application lifecycle management. Virtualization & Workload Migration Designand advise on OpenShift Virtualization (OVE) architectures, leading virtualmachine migration strategies away from legacy hypervisors (specificallyBroadcom/VMware vSphere).

Design Workshops & StakeholderCommunication Lead interactive architecture workshops, effectivelyarticulating complex technical concepts, trade-offs, and deployment strategiesto technical teams and client advisors. Requirements KeyQualifications Platform Track Record Provenhistory of building and deploying enterprise-grade Red Hat OpenShift (OCP)on-premises from scratch for multiple client environments. Proven Hands-On Capability Deepbackground in hands-on implementation and administration. You must possess thepractical, low-level technical ability to actually build, debug, and executethe exact architectures you propose. Application Onboarding Expertise Mandatory hands-on experience working directly with application teams andplatform engineering groups to architect and execute application onboardingonto OCP. Deep Networking & Tooling Expertise Hands-on mastery of OVN-Kubernetes, UDN, Multus, NMState, MetalLB, IstioService Mesh, and GitOps workflows powered by Argo CD. OpenShift Virtualization & VMMigration (Preferred) Hands-on experience with OpenShiftVirtualization (OVE) and migrating virtual machine workloads fromBroadcom/VMware environments.
