This role will report into the Group Head of Information Security.

Monitor vendor feature releases and proactively assess new capabilities, such as new connectors or agent modes, for risk before they reach general use

Maintain a central AI tooling register of approved, restricted and prohibited tools, with documented risk ratings and compensating controls
Translate assessment findings into technical and procedural controls, including access management, logging and monitoring, and prompt and data governance
Secure AI-Assisted Development
Partner with engineering and development teams to embed security guardrails where AI coding tools are used, including code review standards, secrets handling and dependency and IP risk
Define secure-by-design patterns for building internal AI-powered tools or integrations
Third-Party & Vendor AI Governance
Assess AI capabilities embedded in third-party and vendor products, both existing suppliers adding AI features and new AI vendors, as part of vendor due diligence
Contribute AI-specific clauses to vendor contracts and DPAs, covering data use, model training exclusions and sub-processor disclosure
Maintain oversight of shadow AI usage risk across the business
Governance, Reporting & Stakeholder Engagement
Report AI risk posture and control effectiveness to the Group Head of Information Security and relevant governance committees
Support regulatory alignment as it relates to AI tool usage, including DORA, UK GDPR and sector-specific AI guidance
