This is a senior, consulting-led role combining security engineering, architecture, cloud security and cyber risk advisory within a complex enterprise environment.

## About the Role

You’ll act as a trusted technical security advisor, working across engineering, architecture and business teams to deliver secure-by-design solutions and pragmatic, risk-based security controls.

-   Ensure solutions align with relevant regulatory and security frameworks
