Adjacent Technical Skills (Beneficial, Not Required)

Depth in the specialist area above is mandatory. Experience in the following adjacent domains is a strong plus and will be valued in candidate evaluation, since it enables broader solution ownership across engagements.

  • Networking (routing/switching, SD-WAN) given the centrality of hybrid connectivity to this role.
  • Virtualization platforms (VMware, Red Hat OpenShift/OpenStack) as common migration source environments.
  • Security architecture, particularly zero trust and cloud security posture management.
  • Containers and Kubernetes depth beyond managed-service operation.
  • Data platform and analytics services across the hyperscalers (data lakes, warehousing, streaming).
  • AI/ML cloud services, given the growing overlap between cloud migration and AI platform enablement.

Leadership & Delivery Expectations

  • Leads technical delivery independently and acts as the final technical authority on cloud and migration decisions for an engagement.
  • Mentors other cloud architects and engineers across multiple hyperscaler platforms.
  • Navigates multi-vendor, multi-cloud complexity confidently, translating it into a clear, risk-managed migration roadmap for clients.
  • Communicates cloud strategy and migration risk clearly to both hands-on engineering teams and infrastructure leadership.
  • Comfortable owning migration cutover windows and the associated risk management.

Role Summary

World Wide Technology is looking for a deeply technical Enterprise Architect who specialises in cloud and is genuinely fluent across AWS, Azure, and GCP, and equally comfortable designing the hybrid architectures and migration programmes that move clients from on-premises infrastructure into the cloud, and operate confidently in between.

This is a hands-on architecture and delivery role, not a single-cloud specialism. The successful candidate will own the technical delivery of cloud transformation engagements end to end - landing zone design, migration strategy and execution, hybrid connectivity, security, and cost governance acting as the single point of technical accountability from design through to go-live.

While broad, credible depth across hyperscalers and migration methodology is the core requirement, WWT engagements regularly extend into adjacent domains - networking, virtualization, security, and data and experience in these areas is a genuine advantage for this role.

Key Responsibilities

  • Own end-to-end technical delivery of cloud architecture engagements: design authority, low-level design, migration execution, and post-go-live optimisation.
  • Host and chair Architecture Review Board (ARB) and Technical Design Authority (TDA) sessions for cloud engagements, owning governance gates, decision records, and design sign-off.
  • Architect multi-cloud solutions spanning AWS, Azure, and GCP across compute, storage, networking, and identity, selecting the right platform and services for each workload.
  • Lead migration strategy and execution for on-premises to cloud programmes: workload assessment against the 6 R's (rehost, replatform, repurchase, refactor, retire, retain), dependency mapping, wave planning, and low-downtime cutover.
  • Design hybrid cloud architectures connecting on-premises data centres to cloud environments, including dedicated connectivity, hybrid identity, and hybrid DNS/name resolution.
  • Define cloud landing zone and foundation architectures: multi-account/subscription/project strategy, guardrails, and policy-as-code.
  • Advise clients on cloud economics and FinOps: cost visibility, commitment-based discounting, and rightsizing strategy.
  • Define cloud security architecture: identity federation, network segmentation, encryption, and compliance alignment across all three hyperscalers.
  • Lead technical design workshops, present architecture and migration roadmaps to client leadership, and act as the named technical escalation point for delivery teams.
  • Mentor other cloud architects and engineers and contribute to WWT's multi-cloud and migration reference architectures.
  • Support pre-sales through technical scoping, migration effort estimation, and proof-of-concept design.

Required Technical Skills & Experience

Experience Baseline

  • 10+ years in enterprise architecture, infrastructure, or cloud engineering roles.
  • 5+ years working across multiple hyperscale cloud platforms, with demonstrated depth in at least two of AWS, Azure, and GCP and strong working knowledge of the third.
  • Proven track record leading technical delivery (not just advisory) of enterprise-scale on-premises-to-cloud migration programmes.

AWS (Expert Level)

  • Core services: EC2, VPC, S3, RDS, IAM, and Well-Architected Framework application across engagements. Experience or knowledge of AWS Outpost.
  • Landing zone: AWS Control Tower and Organizations for multi-account governance.
  • Networking: Transit Gateway, Direct Connect, and VPC peering/segmentation design.
  • Migration tooling: Application Migration Service (MGN), Database Migration Service (DMS), and Application Discovery Service.
  • Containers: EKS and ECS architecture for modernised workloads.

Azure (Expert Level)

  • Core services: Virtual Machines, Virtual Network, Storage, Entra ID (Azure AD), and Well-Architected Framework application.
  • Landing zone: Azure Landing Zones and Management Group hierarchy design.
  • Networking: ExpressRoute and Virtual WAN for hybrid and multi-region connectivity.
  • Migration tooling: Azure Migrate for assessment, replatforming, and cutover.
  • Containers: AKS architecture for modernised workloads.

GCP (Strong Working / Expert Level)

  • Core services: Compute Engine, VPC, Cloud Storage, and Cloud IAM.
  • Landing zone: Resource Manager hierarchy and Organization Policy design.
  • Networking: Cloud Interconnect and hybrid connectivity design.
  • Migration tooling: Migrate to Virtual Machines for workload migration.
  • Containers: GKE architecture for modernised workloads.

Migration & Modernization

  • Deep working knowledge of migration assessment methodology (the 6 R's) and the tooling used to apply it
  • Experience building application dependency maps and translating them into realistic, risk-managed migration wave plans.
  • Data migration strategy for both online (minimal downtime, replication-based) and offline (bulk transfer) approaches.
  • Hands-on experience leading cutover events for production workloads, including rollback planning.

Hybrid Cloud Architecture

  • Design of dedicated hybrid connectivity: Direct Connect, ExpressRoute, and Cloud Interconnect, including integration with existing SD-WAN and WAN environments.
  • Hybrid identity architecture: AD Connect/Entra Connect, federation, and single sign-on across on-premises and cloud directories.
  • Hybrid DNS and name resolution design across on-premises and multi-cloud environments.
  • Experience with VMware-on-cloud bridge technologies (VMware Cloud on AWS, Azure VMware Solution, Google Cloud VMware Engine) as a migration and coexistence strategy.
  • Workload placement strategy for organisations operating a genuinely long-term hybrid estate, not just a transitional one.

Landing Zone, Governance & Automation

  • Multi-account/subscription/project strategy design and the guardrails (SCPs, Azure Policy, GCP Organization Policy) that enforce it.
  • Infrastructure-as-code proficiency: Terraform as a primary, cross-cloud standard, plus native tooling (CloudFormation, Bicep/ARM) where required.
  • Tagging, cost allocation, and resource organisation standards that support governance and FinOps at scale.
  • CI/CD and GitOps practices for infrastructure delivery across multi-cloud environments.

Security & Compliance

  • Identity federation and zero trust principles applied consistently across AWS, Azure, and GCP.
  • Network security design: security groups/NSGs, cloud-native firewalls, and web application firewalls.
  • Encryption at rest and in transit, and key management across multi-cloud environments.
  • Working knowledge of relevant compliance frameworks (e.g. SOC 2, ISO 27001, and sector-specific regimes) as applied to cloud architecture.

FinOps & Cost Optimisation

  • Practical experience with cost visibility and management tooling (Cost Explorer, Azure Cost Management, GCP Billing reports).
  • Commitment-based discount strategy: reserved instances, savings plans, and committed use discounts.
  • Rightsizing and autoscaling strategy to control cost without compromising resilience.

Automation & Observability

  • Cloud-native observability across all three hyperscalers (CloudWatch, Azure Monitor, GCP Cloud Operations Suite), plus familiarity with third-party platforms (Datadog, Splunk) for unified multi-cloud visibility.
  • Automated compliance and drift detection tooling integrated into infrastructure-as-code pipelines.

Architecture Governance & Design Authority

  • Proven experience hosting and chairing formal Architecture Review Board (ARB) and Technical Design Authority (TDA) forums, including agenda ownership, decision logging, and stakeholder facilitation.
  • Ability to define and operate governance gates across the engagement lifecycle: design authority sign-off, change control, and exception/waiver management for cloud and migration decisions.
  • Experience producing and maintaining architecture decision records (ADRs), design standards, and reference architectures that are actively enforced through ARB/TDA governance.
  • Comfortable presenting and defending architecture decisions to senior client governance bodies, including constructively challenging non-compliant or high-risk designs.

Communication & Delivery

  • Excellent executive communication and presentation skills; able to flex between deep technical detail and C-suite framing on cloud strategy and migration risk.
  • Proven ability to author low-level design (LLD) and high-level design (HLD) documentation, and migration runbooks, to a professional services standard.
  • Experience running technical design workshops with senior client stakeholders and multi-vendor delivery teams.
