Sepal AI partners with top AI research labs (OpenAI, Anthropic, Google DeepMind) to determine how dangerous AI models are. We need hackers, red-teamers, and CTF veterans to work with the newest LLM coding models to understand what they're capable of and to hack our CTFs.

🧠 What You'll Do

  • Design adversarial scenarios that probe AI assistants for injection, privilege-escalation, and data-exfiltration risks.

  • Execute red-team engagements against AI-enabled workflows (web, cloud, and SaaS).

  • Craft realistic exploit chains and payloads a real attacker might use, then measure whether the model blocks or facilitates the attack.

  • Build scoring rubrics, attack trees, and reproducible test harnesses to grade model resilience.

  • Collaborate with AI researchers to iterate on defenses, patch vulnerabilities, and improve sandboxing & policy enforcement.

āœ… Who You Are

  • OSCP (or comparable) certification and 3+ years in professional red teaming or offensive security.

  • Proven CTF track record; comfortable with web, cloud, and application exploits.

  • Fluent in Python/Bash tooling, custom payload development, and exploit automation.

  • Strong grasp of common enterprise stacks (OAuth, SAML, REST, SQL, cloud IAM).

  • Passionate about AI safety and eager to keep cutting-edge models from becoming attack surfaces.
