The Opportunity

Are you tired of roles that force you to choose between pure support and pure architecture? This opportunity sits right in the middle. You'll design, build, operate, and evolve a modern enterprise platform, taking full ownership of identity, automation, and infrastructure services across both on-prem and cloud environments. This is a hands-on technical leadership position within a large, high-profile organisation undergoing significant infrastructure transformation over the next 3-5 years. If you want a role where you won't get boxed in, where you can use your breadth across identity, cloud, automation, and infrastructure, this is the one.

What You'll Do

  • Own and evolve the enterprise identity & infrastructure strategy
  • Build and deliver roadmaps, principles, guardrails, and operational patterns
  • Lead the design, build and operation of the organisation's next-gen platform
  • Drive adoption of Infrastructure-as-Code and automation (Terraform, Ansible, GitLab)
  • Partner closely with Security and Architecture to ensure a secure, evergreen, resilient platform
  • Act as a senior technical authority during incidents, outages, and complex engineering challenges
  • Support the shift to a modern "as-a-service" infrastructure model
  • Contribute directly to a multi-year transformation across cloud, data centre, identity, and automation

This is not a detached architect role, you will stay close to the technology, get hands-on when needed, and influence key strategic decisions.

What You Bring

You're the ideal fit if you sit between a Senior Engineer and a Technical Architect - someone who can both design and deliver.

Essential Skills & Experience

  • Identity (priority area): Strong experience across Entra ID, Active Directory, Azure SSO, Conditional Access (must have), App Registrations / Enterprise Applications, One Identity Active Roles, JIT access, ZTNA concepts, and ideally zScaler
  • Infrastructure & Platform: VMware (VCF ideally), Linux (Ubuntu, RedHat), Microsoft stack, Storage, OS, data centre fundamentals, Networking (WAN/LAN, routing, firewalls, IDS/IPS, WLAN, load balancing)
  • Automation (non-negotiable): Terraform, Ansible, GitLab (pipelines, automation, patterns)

You're also someone who:

  • Has evolved with the industry - not stuck in on-prem only or cloud-only silos
  • Thinks in terms of platforms, not just ticket queues or pipeline building
  • Can influence and negotiate with senior stakeholders
  • Communicates clearly at both technical and non-technical levels

Why This Role Is Different

This isn’t a siloed identity role. This isn’t a PowerPoint architect role. This isn’t a narrow engineer role. This is a broad, modern, engineering-led role covering identity, infra, cloud, automation, and platform operations. You’ll gain exposure across multiple domains and work in a genuinely collaborative environment where your expertise shapes the future platform. You won’t get boxed in here.
