• Develop, modify, and safely use scripts, payloads, tooling, and tradecraft to support realistic adversary emulation.

AI Security Responsibilities

• Support adversarial testing of AI and LLM systems, including prompt injection, data leakage, tool misuse, model behavior abuse, and guardrail bypass scenarios.
• Analyze AI-enabled applications, copilots, automation workflows, agents, plugins, APIs, and data integrations for security and abuse risks.
• Document AI security observations in clear business and technical terms, including risk impact, exploitability, control gaps, and recommended remediation.
• Use AI-assisted analysis responsibly to accelerate research, data review, reporting, detection mapping, and test-case development.
• Track emerging AI threats, attacker use of AI, and relevant industry guidance to inform Red Team scenarios and validation priorities.

Threat Tradecraft & Capability Development
