📋 Description

• 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

• 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.
