Job Description

A repeat YC founder is building autonomous cybersecurity agents that attack and defend for real, trained in RL environments against real vulnerabilities.

Looking for a founding engineer with a deep offensive and defensive security background and real AI chops, who wants to own the technical core from day zero, with cofounder equity to match.

The bet.

Security is going autonomous. The agents that find, exploit, and patch vulnerabilities will be trained, not prompted. We build the RL environments where cyber agents learn against real vulnerabilities with deterministic grading, and we train the agents themselves. The verified environment is the moat, not the weights.
