• Define and build engineered security controls for AI/ML and LLM-related risks.
• Build security automation and developer-facing tooling that helps product and engineering teams build securely by default.
• Review new AI solutions and system architectures for security risk, and represent security in AI governance forums and the AI solutions catalogue.
