AI training jobs for scientists, mathematicians and PhDs
Frontier models are tested on graduate-level problems, and labs need experts to write and check them. Typical work is writing hard questions with verified answers, checking step-by-step solutions, and grading a model's reasoning.
Many roles ask for a PhD or current PhD study in the field. Some math roles involve formal proof tools like Lean.
