##

Overview

The AWS Cloud Architect is a senior strategic and technical leadership role responsible for the design, governance, and evolution of enterprise cloud architecture across multi-region AWS environments. This position will drive the assessment and migration of legacy on-premises workloads to cloud-native architectures, define and enforce infrastructure and delivery standards, and govern hybrid environments that span both on-premises data centres and AWS. Operating within the payments industry, the successful candidate will ensure all architectural decisions are aligned with organisational objectives, PCI DSS compliance obligations, and industry best practices. The role requires strong collaboration with engineering teams, operations, security, and executive stakeholders to define scalable, secure, and cost-effective cloud strategies — while providing technical leadership, mentoring, and architectural governance across the broader engineering organisation.

Responsibilities

Key Responsibilities

• Define and own the cloud architecture strategy across multi-region AWS environments, ensuring alignment with business objectives, security requirements, and compliance obligations.
• Lead the planning and execution of cloud migration programmes, taking legacy on-premises workloads through lift-and-shift and progressively re-architecting them to cloud-native patterns.
• Architect and govern hybrid environments spanning on-premises data centres and AWS, including private connectivity, identity federation, hybrid DNS, and unified observability.
• Design highly available multi-region architectures incorporating active-active and active-passive configurations, automated failover, global load balancing, and data replication strategies.
• Define infrastructure-as-code standards using Terraform and Terragrunt, including module governance, policy-as-code guardrails, and multi-account state management strategies.
• Architect and oversee GitLab-based CI/CD platforms, setting delivery standards for infrastructure and application pipelines across multiple engineering teams.
• Ensure all cloud architecture meets the compliance and regulatory requirements of the payments industry, including PCI DSS, SOC 2, and regional data sovereignty obligations.
• Produce and maintain architecture documentation, reference architectures, Architecture Decision Records (ADRs), and multi-year technology roadmaps.
• Lead architecture review processes, providing technical governance across major engineering initiatives and acting as the final escalation point for complex infrastructure decisions.
