THE ROLE

You will work closely with technology, operations and business teams to provide architectural guidance across on-premises, cloud and SaaS environments. Your expertise will help shape security designs, support the development of reference architectures and security patterns, and enable effective risk-based decision making. You'll bring experience of security architecture within complex technology environments, together with a practical understanding of recognised frameworks such as NIST, ISO 27001, MITRE ATT&CK or NCSC guidance. You will be comfortable engaging with a broad range of stakeholders and translating security requirements into clear, practical solutions. We're looking for someone who enjoys collaboration, approaches challenges with curiosity and pragmatism, and can communicate effectively with both technical and non-technical audiences. Experience within financial services or another regulated environment would be beneficial, as would knowledge of AI-enabled technologies and their associated security considerations.
