Develop advanced detection methods to identify and analyze AI tools, agents, and their behavior.

Design risk assessment frameworks to evaluate AI agents’ permissions, data access, tool usage, and potential for data leakage or abuse.

Conduct adversarial research on AI agents and agentic frameworks (prompt injection, tool abuse, excessive agency, data exfiltration) and propose mitigations and policy controls.

Collaborate with engineers and product leaders to turn research into capabilities of our AI security platform.

Maintain awareness of the latest research and technologies in security, AI, and trust, and evaluate their relevance for our innovation pipeline.

Excellent problem-solving skills and ability to lead research independently in a fast-paced, collaborative environment.

Preferred Requirements:

Experience researching for security products (e.g., threat detection or data protection solutions).

Experience with macOS security research, including macOS internals (e.g., XNU, launchd, TCC, system extensions, code signing and notarization).

Hands-on experience with agentic AI frameworks (LangChain, AutoGen, CrewAI, Semantic Kernel, etc.) and their associated security risks.

Familiarity with AI security toolkits (e.g., Garak, PyRIT, LLM Guard, NeMo Guardrails).

Publications, conference talks, or CVEs in security or AI security.
