We’re looking for a Principal Cloud Architect to be the senior technical authority for cloud architecture across RS&AM Engineering, shaping the design and evolution of cloud-native platforms and services on AWS. Combining deep hands‑on expertise with technical leadership, the role defines architecture patterns, builds reference implementations, and sets engineering‑led standards that enable scalable, secure, and high‑performing solutions.

In our Engineering & Transformation you’ll report to the Head of Cloud Platform, translating platform strategy into practical, implementable architectures, leading through working solutions rather than governance alone.

Responsibilities

• Define and own cloud architecture direction across RS&AM, setting principles, patterns and target‑state architectures aligned to platform strategy
• Act as senior authority for AWS architecture, leading complex design decisions, resolving high‑impact technical challenges and driving simplification, standardisation, and alignment across the estate
• Design, build, and deploy reference architectures and proof of concepts, establishing reusable blueprints and implementation patterns to enable consistent, scalable delivery across teams
• Define and evolve cloud standards and guardrails through modern engineering approaches to ensure secure, resilient, and consistent AWS solutions
• Embed security, resilience, and control requirements into architecture, aligning engineering‑led solutions with enterprise standards, where required, balancing delivery pace with risk and control expectations
• Strong experience with serverless and distributed architecture patterns with deep hands‑on AWS expertise, including designing and deploying cloud‑native solutions
• A track record of setting technical direction across multiple teams or domains with proven experience as a Principal Engineer, Architect, or equivalent senior technical leader

We want to hire the whole version of you.

We’re committed to ensuring that everyone feels accepted and welcome and we are happy to consider applicants from all backgrounds. If your experience looks different from what we’ve advertised and you believe that you can bring value to the role, we’d love to hear from you.
