Key Responsibilities

• Define enterprise security architecture strategy, principles, reference architectures, reusable patterns, and multi-year roadmaps across network, endpoint, identity, application, cloud, container, data, and detection and response domains

• Lead security architecture engagement for complex, high-risk, and cross-functional programs; translate business objectives, threat intelligence, and risk appetite into scalable technical controls and design requirements

• Establish architecture and security requirements for AI/ML systems, including secure MLOps, model and data lifecycle protection, identity and authorization, platform isolation, model provenance, monitoring, privacy, and responsible-use guardrails

• Review generative and agentic AI designs—including retrieval-augmented generation, vector databases, third-party models, APIs, plugins, tools, and autonomous actions—and address controls to mitigate the risks of prompt injection, data leakage, excessive agency, insecure output handling, and AI supply-chain compromise
