About the role

Key responsibilities & impact
  • You'll design and build LLM-powered systems and agents that integrate into and perform real offensive security work.
  • Autonomous hacking agents. LLM agents that perform full attacks with minimal human intervention.
  • Agent architecture. Planning loops, tool use, memory, and state management that let agents reason across long, multi-step attack chains.
  • Prompting and orchestration. Translating attacker workflows and tradecraft into prompts, decision graphs, and orchestration layers.
  • Tool integration. Writing custom agent tooling, integrating third party tools as well as wrapping the offensive security toolchain into agent-callable interfaces.
  • AI feature development. Building AI solutions that solve real-world problems.
  • Evaluation and benchmarking. Building eval harnesses and realistic target labs.
  • False positive reduction. You'll work on validation logic and reasoning chains that eliminate hallucinated vulnerabilities.
  • Production reliability. Testable, observable, maintainable systems.
  • Broader applied AI and tool research.

Requirements

What you’ll need
  • Hands-on experience building with LLMs - using the likes of Claude Code, and Codex to build out projects and accelerate dev workflows.
  • Engineering ability in Python or TypeScript - you can write and ship reliable code.
  • Some experience building AI solutions: even if at a small scale, you have experience writing prompts, thinking about tool use, agent loops and/or AI evaluation.
  • Strong ownership and a self-starter mindset.
  • A big-picture thinker, comfortable with ambiguity.
  • Clear written communication.
  • Professional offensive security experience: penetration testing, red teaming, bug bounty, or equivalent.
  • Strong production engineering: architecting and owning systems end to end, including deployments and CI/CD pipelines.
