What You'll Do
We're looking for an AI Researcher to build the agents that turn our offensive knowledge into defensive action.
You'll build agents that reason from a proven attack path to the specific control changes that break it - EDR policy, firewall and segmentation rules, conditional access, detection content, cloud IAM, GPO - apply or stage those changes in the customer's environment, and then prove the fix by re-running the attack.
That last part is why this is tractable. Most defensive AI has no ground truth and gets graded on whether its advice sounds reasonable. Ours gets graded on whether the attack still works. You will have a real outcome signal on a short loop, and hundreds of thousands of prior tests to learn from. It is also why this is hard. These agents run inside customer tenants and modify production security controls. A bad change is an outage or a new hole in someone's defense. The reasoning problem and the safety problem are the same problem here, and you will own both.
