Member of Technical Staff, Evals Lead

We’re hiring an Evals Lead to benchmark video and world-model capabilities with and without our data. You need to deeply understand the philosophy of evals: what an eval is allowed to claim, contamination, leakage, construct validity, and whether a number actually corresponds to a capability. More practically, you should have pushed consequential evals before — evals that changed what a lab trained, shipped, or collected, not a weekend leaderboard.
