Profile Summary
The DevSecOps architect will enable delivery of:
- Published target-state infrastructure architecture and placement policy, endorsed at Design Authority.
- Agreed and sequenced data centre exit plan with named workloads, waves, and dates.
- VDI consolidation roadmap approved, with the first platform migration wave delivered.
- Baseline infrastructure cost model established, and a measurable reduction path committed.
Own the target-state infrastructure architecture across end-user compute, data centre estate, and cloud, and drive the consolidation of three historically separate estates into one coherent, cost-managed platform. This is a consolidation and exit role as much as a design role: the measure of success is estate reduction, not estate growth.
Duties And Responsibilities
- Define the target-state infrastructure architecture spanning virtual desktop infrastructure, physical and colocated data centres, and public cloud, with a clear placement policy governing what runs where and why.
- Lead the data centre rationalisation programme: workload discovery and dependency mapping, migration wave planning, exit sequencing, and lease/contract alignment.
- Consolidate the VDI and end-user compute estate — rationalise brokers, images, profile management, and licensing; define persona-based desktop patterns; set the roadmap from legacy VDI toward a single strategic platform.
- Design cloud landing zones, network topology, identity integration, and hybrid connectivity to support migration at scale without re-platforming the operating model per application.
- Establish infrastructure standards: compute and storage tiering, virtualisation, backup and archive, patching, and infrastructure-as-code baselines.
- Own resilience architecture — disaster recovery tiering, recovery time and point objectives, failover design and testing — aligned to operational resilience and important business service requirements.
- Build and maintain the infrastructure cost model; drive unit economics, capacity forecasting, and rightsizing; make consumption visible to service owners.
- Partner with network, security, EUC, and platform engineering teams to sequence dependencies and avoid stranded estate.
- Provide assurance at Design Authority for infrastructure change; challenge project-level decisions that create new estate outside the target state.

Qualifications, Skills And Experience
- Substantial infrastructure architecture experience in a regulated enterprise, with at least one end-to-end data centre consolidation, migration, or exit delivered.
- Demonstrable ownership of a VDI or end-user compute estate at enterprise scale, including a platform migration or consolidation.
- Hands-on architecture across at least one major public cloud, covering landing zone design, networking, identity, and migration patterns.
- Proven capability in workload discovery and dependency analysis for legacy estate, including undocumented systems.
- Track record of infrastructure cost reduction supported by evidence, not forecast.
