• Design and deliver secure architectures for AI-driven and agentic systems (LLMs, RAG, autonomous agents), addressing emerging risks such as prompt injection, data poisoning, and model/data leakage

• Define and implement security controls across the AI lifecycle (data, model, inference, orchestration), embedding governance, identity, and policy into LLMOps/MLOps pipelines

• Advise clients on securing human-to-agent and agent-to-agent interactions, applying zero trust principles and ensuring auditability, compliance, and safe autonomous behavior in production environments

Knowledge and Attributes

• Advanced knowledge of security architecture, IAM, PAM, endpoint protection, cloud security, network security, and threat modelling.
