Job description

OpenShift Architect (On-Premises Infrastructure & GitOps)

Location: On-site (Ireland [preferred], UK, EU) / Hybrid (twice a week D18)

Start date: 2nd week of November 2026

Role Overview

We

are seeking an expert OpenShift Architect to lead the technical design,

build, and implementation of our on-premises Red Hat OpenShift Container

Platform (OCP) infrastructure. In this end-to-end technical role, you will take

full ownership of the platform lifecycle - facilitating design workshops,

building GitOps-driven architectures, driving application onboarding, and

executing greenfield deployments from scratch in a highly regulated

environment.

Key Responsibilities

● End-to-End Execution: Drive

all technical deliverables across the full project lifecycle, from initial

concept and High-Level Design (HLD) / Low-Level Design (LLD) to hands-on build

and infrastructure implementation.

● Greenfield OCP Deployment: Deploy, configure, and validate on-premises Red Hat OpenShift Container

Platform clusters from scratch across multiple client environments.

● Application Onboarding & Team

Engagement: Actively engage with platform engineering and

application teams to establish onboarding patterns, developer workflows, and

migration 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), Multus

CNI (for multi-network Pod interfaces), NMState / NNCP for host node

networking, MetalLB / BGP for on-prem load balancing, Ingress/Egress

routing, and Service Mesh (Istio / Red Hat OpenShift Service Mesh).

● GitOps & Continuous Delivery: Implement GitOps practices using Argo CD / OpenShift GitOps for

automated, version-controlled cluster provisioning, configuration management,

and application lifecycle management.

● Virtualization & Workload Migration: Design

and advise on OpenShift Virtualization (OVE) architectures, leading virtual

machine migration strategies away from legacy hypervisors (specifically

Broadcom/VMware vSphere).

● Infrastructure & Security Integration: Integrate platform architecture with enterprise storage (CSI, persistent

storage solutions), physical datacenter hardware, and strict security

baselines.

● Design Workshops & Stakeholder

Communication: Lead interactive architecture workshops, effectively

articulating complex technical concepts, trade-offs, and deployment strategies

to technical teams and client advisors.

Requirements

Key

Qualifications

● Platform Track Record: Proven

history of building and deploying enterprise-grade Red Hat OpenShift (OCP)

on-premises from scratch for multiple client environments.

● Proven Hands-On Capability: Deep

background in hands-on implementation and administration. You must possess the

practical, low-level technical ability to actually build, debug, and execute

the exact architectures you propose.

● Application Onboarding Expertise: Mandatory hands-on experience working directly with application teams and

platform engineering groups to architect and execute application onboarding

onto OCP.

● Deep Networking & Tooling Expertise: Hands-on mastery of OVN-Kubernetes, UDN, Multus, NMState, MetalLB, Istio

Service Mesh, and GitOps workflows powered by Argo CD.

● OpenShift Virtualization & VM

Migration (Preferred): Hands-on experience with OpenShift

Virtualization (OVE) and migrating virtual machine workloads from

Broadcom/VMware environments.

● Regulated Environment Mandate: Mandatory experience operating within strictly compliant, high-security

industries (e.g., Banking, Healthcare, Defense, or Telecoms).

● Clear Communication & Advising: Excellent verbal and written technical communication skills, with a

demonstrated ability to advise client stakeholders and justify architectural

decisions.

● Datacenter & Storage Fundamentals: Strong

background in bare-metal datacenter infrastructure, enterprise storage

integrations, and automation (Ansible, Terraform).
