The Role

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 are committed to ensuring that everyone feels accepted and welcome applicants from all backgrounds.
