Cloud Architect; DV Security Cleared

The Cloud Architect is responsible for analysing existing on-premise systems and designing, planning, and supporting their migration into a secure, scalable, and cloud-native environment. The role focuses on modernising architectures, leveraging managed services, and ensuring migrations deliver measurable business and technical benefits, while working closely with technical stakeholders across multiple teams.

• Analyse existing on-premise infrastructure, applications, and integrations, including compute, storage, networking, security, and operational processes.
• Classify workloads using recognised migration strategies (e.g. 6
  
  Rs: Rehost, Replatform, Refactor, Retire, Retain, Replace).
• Capture non-functional requirements including availability, performance, security, compliance, and cost considerations.

• Design target-state architectures aligned with cloud-native best practices.
• Define architectures leveraging AWS services such as:
  Compute, Networking, Storage & Data, Security, and Observability.
• Produce clear architecture artefacts including diagrams, ADRs, migration runbooks, and landing zone designs.

• Create and maintain migration plans and roadmaps, including sequencing, dependencies, risks, and rollback strategies.
• Support or lead migration activities including environment build, application migration, data migration, and cutover support.
• Ensure cloud environments are secure, resilient, scalable, and cost-optimised.

• Work closely with technical stakeholders, including application owners, infrastructure engineers, Dev Ops teams, security specialists, and architects, to understand current systems and future requirements.
• Clearly communicate architectural decisions, trade-offs, risks, and assumptions, ensuring stakeholder buy-in and alignment.

• Strong experience with on-premise infrastructure (VMware, physical servers, networking, storage).
• Proven experience designing and delivering cloud architectures.
• Deep understanding of core cloud services, networking, and security.
• Experience working closely with technical stakeholders across multiple disciplines.
• Strong communication skills, able to explain complex technical concepts clearly.

• Experience with containerisation and orchestration platforms (e.g. Docker, Kubernetes, or equivalent technologies).
• Experience with Infrastructure as Code (IaC) using industry-standard tools (e.g. Terraform, ARM, Bicep, Pulumi, or similar).
• Familiarity with CI/CD pipelines and Dev Ops tooling, supporting automated build, test, and deployment workflows.
• Relevant cloud or platform certifications (e.g. cloud architecture, Dev Ops, or infrastructure certifications from recognised providers).
