  • Governance & Operations: Establish a scalable operating model for AI security, including standards for threat modeling, vulnerability management, and incident response specific to AI systems.
  • Guardrails Enforcement: Drive adherence and enforcement of guardrails through technical enforcement where feasible (policy-as-code, platform controls, continuous monitoring), e.g. through embedding automated controls into pipelines and platforms.
  • Offensive Testing: Partner with offensive testing team on AI security testing at scale (prompt injection/jailbreak testing, data leakage testing, adversarial evaluation harnesses, agent misuse scenarios).
  • Requirements Setting: Set enforceable requirements for external models, copilots, AI SaaS, and integrators (data handling/retention, telemetry/logging, incident notification, assurance evidence, contractual clauses).
  • Stakeholder Partnership: Serve as the primary security partner to the Enterprise AI platform team, as well as Engineering, Data Governance, Legal, Privacy, and BISO teams to embed security into their processes.
  • Threat Innovation: Stay at the forefront of AI security research, identifying emerging threats, evaluating new tools, and pioneering innovative defensive measures to protect our data, customers, and brand.
