About the Role

The Technology Architect – Network, Cloud & Hosting (Compute/Storage) is a hands on architecture role within Digital & Technology (D&T), accountable for defining and governing Customer's network and hosting architecture foundation, where hosting explicitly includes cloud and on prem compute and storage.

Reporting into the Technology Domain Architect, the role translates enterprise technology direction and standards into implementable network + hosting architectures that are secure by design, resilient by default, globally consistent and operable at scale.

The scope covers architecture across enterprise connectivity and hosting foundations. The domains below are illustrative examples only and are not exhaustive.

Scope (sample domains — not exhaustive)

Networking – example common domains (not exhaustive):

• LAN / Campus networks (wired access, switching, segmentation)

• WAN (MPLS/IPVPN, broadband/internet)

• SD WAN (policy driven routing and optimisation)

• Cloud networking (VNET/VPC design patterns, hub and spoke, segmentation)

• Hybrid connectivity / cloud interconnect (private connectivity patterns)

• DDI (DNS / DHCP / IP Address Management)

• Global traffic management / load balancing patterns (where applicable)

• Network observability and telemetry (performance/availability monitoring patterns)

Hosting (Compute & Storage) – example common domains (not exhaustive):

• On prem compute (data centre compute and virtualised compute patterns)

• Private cloud compute (orchestrated private cloud patterns)

• Public cloud compute (IaaS compute and cloud compute services)

• Container platforms (container runtime and managed container patterns)

• Storage (block, file and object storage patterns)

• Data protection (backup, snapshot, retention and recovery patterns)

• Environment / tenancy patterns (dev/test/prod separation, shared services, tiered subnet models)

• Resilience and DR architecture (replication assumptions, failover patterns, recovery readiness)

Important: The above lists are examples only and are not exhaustive. The role will cover additional networking and hosting domains as required to support enterprise outcomes, platform convergence and secure, resilient operations.

Role purpose

To design and govern a modern, simplified, secure and resilient network and hosting foundation, covering enterprise connectivity plus cloud/on prem compute and storage, enabling reliable operations and scalable delivery for Customer's enterprise platforms and digital products.

Key accountabilities

The Technology Architect – Network, Cloud & Hosting (Compute/Storage) is accountable for:

• Defining and evolving reference architectures and standards across network and hosting domains (sample list above is not exhaustive) to reduce fragmentation and accelerate delivery.

• Driving simplification and standardisation, reducing bespoke patterns across regions/sites and reducing technology sprawl.

• Ensuring designs are secure by design and resilient by default, including recoverability, observability and operational readiness.

• Providing architecture governance and implementation guidance to delivery and operations teams (design → build → deploy → operate).

Key responsibilities

1. Modern Network Reference Architecture (All Network Domains)

• Define and maintain standard architectures across key networking domains (LAN, WAN, SD WAN, cloud networking, DDI, cloud interconnect) to enable globally consistent, secure connectivity patterns.

• Provide practical reference patterns and guidance that teams can implement consistently at scale.

2. Hosting Architecture (Cloud + On Prem Compute and Storage)

• Define and maintain the enterprise hosting architecture covering cloud and on prem compute and storage patterns (including virtual machines, container patterns where used, and storage services).

• Ensure hosting choices drive standardisation, automation, cost efficiency and flexibility while remaining supportable at enterprise scale.

•

3. Cloud Landing Zone & Environment Standards

• Define and govern cloud foundation patterns for environment/tenancy separation and shared services so teams can adopt consistent secure defaults.

• Ensure cloud network and hosting designs remain aligned and enforceable across regions and workloads.

4. Secure by Design & Resilient by Default Foundations

• Ensure network and hosting architectures embed security controls, segmentation and policy alignment points, as well as resilience patterns (availability, failover, recoverability and operational readiness).

• Partner with Cyber and Operations stakeholders to ensure architectures are operable and support continuity expectations.

5. Data Protection, Backup and Recovery (Architecture)

• Define architectural standards and patterns for data protection and recovery (backup, snapshot, retention and recovery expectations), ensuring they are designed in from the outset for production ready workloads.

(Architecture defines the standards and patterns; operations own day to day execution.)

6. Standardisation, Simplification & Convergence

• Reduce bespoke site and regional variance where not required and steer towards a small number of strategic patterns and shared services for network and hosting foundations.

• Identify duplication and architectural debt and recommend remediation approaches aligned to enterprise direction.

7. Architecture Governance & Delivery Assurance

• Provide governance through design reviews, standards compliance checks and delivery checkpoints; document decisions and trade offs clearly.

• Escalate systemic issues and recommendations through the Technology Domain Architect.

8. Cross Domain Enablement

• Work with Domain Architects and platform teams to ensure network and hosting foundations enable end to end enterprise programmes without creating bottlenecks or one off exceptions.

What good looks like

• A modern, standardised network foundation across LAN/WAN/cloud networking/DDI with reduced fragmentation.

• A clear, consistent hosting foundation for cloud and on prem compute and storage, with reusable patterns and reduced bespoke build.

• Landing zone and environment standards accelerate delivery while strengthening secure defaults.

• Resilience and recoverability are designed in up front, not retrofitted.

Qualifications & experience

Essential

• Demonstrated experience as a Network / Infrastructure / Cloud Architect in complex enterprise environments.

• Strong understanding across LAN/WAN, SD WAN, cloud networking, DDI and enterprise connectivity design.

• Experience architecting hosting foundations including cloud and on prem compute and storage, and defining standard environment patterns.

• Proven ability to guide delivery and operations teams through architecture governance and implementation decisions.

Preferred

• Experience designing cloud landing zones and multi region hosting patterns.

Skills & capabilities

• Deep network architecture capability (routing, segmentation, connectivity, DDI fundamentals)

• Hosting architecture capability (cloud/on prem compute and storage patterns, environment design)

• Strong non functional design mindset (availability, resilience, operability, recoverability)

• Clear communication and ability to influence engineering, security and operations stakeholders
