Generalists

Mercor is hiring highly detail-oriented Generalists on behalf of an AI lab to support human data pipelines used to train and evaluate advanced AI systems. This role is ideal for people who are extremely quality-focused, methodical, and take pride in producing consistently high-accuracy work. You’ll work on structured evaluation, labelling, and review tasks where precision matters more than speed. Small mistakes compound here — we’re looking for people who notice edge cases, inconsistencies, and ambiguity instinctively.
