Offensive Security RL Researcher

idler is looking for an elite security researcher who can also build. You'll lead idler's cybersecurity work: deciding which environments we build, building and running the systems that produce them, recruiting and managing the part-time experts who review them, and working directly with researchers at frontier AI labs to understand what they need and sell them what we build.

You're a security researcher first. We need someone whose judgment about what counts as a real vulnerability, what makes a task fair, and where the field's genuine skill hierarchy actually sits, we can trust without double-checking. Software development is the tool you use to put that judgment into a production pipeline — it's not a second, parallel discipline we're hiring for separately.

One note on scope: if idler stops investing in cybersecurity, you'd move to a different project inside the company rather than leave — we want to say that plainly now rather than have it be a surprise later.
