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.

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
