A JD tells us what to build. It rarely tells us who will thrive building it. The hires that actually work almost never look best on paper. They're the ones still shipping two years later, the ones who raise the bar. They match what the JD doesn't say.
This brief is how we capture what doesn't make it into a JD: how your team actually works, what made your last great hire great, what your last misfire taught you. Every field is optional. The more you share, the tighter what comes back. Mostly taps. No essays.
