- AI Security Expertise: Hands-on experience assessing or red-teaming LLMs, generative AI tools, or AI-integrated SaaS products; familiarity with adversarial ML, model extraction, prompt injection, or data poisoning.
- Security Research Skills: Proven ability to design and execute independent research- identifying vulnerabilities, publishing technical findings, and proposing mitigations.
- Communication & Storytelling: Excellent written and verbal skills for translating complex research into accessible content - whether blog posts, practitioner guides, or conference talks.
- Public Presence: A strong desire to build a profile for presenting or contributing to security or AI conferences (e.g., Black Hat, DEF CON, RSA)
