Key Responsibilities - AI Security Architecture & Strategy: Own enterprise AI security architecture across Generative AI platforms, AI agents, ML pipelines, and the full model lifecycle (data ingestion, training/fine-tuning, deployment, monitoring), including internal and third-party foundation models. Establish security reference architectures, patterns, and guardrails for prioritized AI use cases. Maintain the AI security roadmap and lead architecture/security design reviews; document decisions, exceptions, and compensating controls. - AI Threat Modeling & Risk Management: Lead AI threat modeling and abuse-case analysis (e.g., prompt injection, data poisoning, model extraction, hallucination abuse, agent misuse). Define and validate controls for AI risks (misuse/abuse, data leakage/privacy, unauthorized agent actions, supply chain/provenance). Operationalize AI security testing (red-teaming/adversarial testing). Partner with IR/SOC on AI-specific detection and response playbooks. Embed AI risk into Enterprise Risk Management (ERM) processes. - Secure AI Platform Enablement: Architect secure AI platform implementations (agent frameworks, orchestration layers, vector databases/embeddings, model APIs/inference gateways). Define identity, access, and authorization for humans and AI agents; ensure integration with IAM, secrets management, logging/monitoring, and SOC workflows. Establish secure RAG patterns (classification, grounding, filtering, tenant isolation, least-privilege retrieval) and agent guardrails (tool allowlists, scoped credentials, approvals, rate limits, sandboxing). - Governance, Standards & Compliance: Establish AI security policies, standards, and control requirements aligned to relevant frameworks and regulations (e.g., NIST AI RMF, ISO/IEC 27001/23894, SOC 2, SOX, GLBA, GDPR).
