• Conduct threat modelling (AI-specific and traditional) and risk reviews
• Support the embedding security across the end-to-end agentic SDLC (design, test, release, governance)
• Develop reusable security patterns and standards for engineering teams
• Support secure go-to-market processes for new products and capabilities
• Partner with engineering teams to ensure effective handover and implementation
• Validate infosec hypothesis through the build and testing of POCs and Pilots with hands‑on POCs
• Support the scoping, build, and industrialization of infosec AI projects across the org.
• Work closely with the Principal Info Sec AI architect and wider infosec architecture team to ensure the scoping and delivery of solutions are aligned to the Strategy
