We're looking for UK or Europe-based generalist experts to help train and evaluate frontier AI models. In this role, you'll review and assess a wide range of everyday professional content — documents, slides, spreadsheets, and other written materials — judging them for quality, accuracy, clarity, and completeness. Your feedback directly shapes how AI systems reason about and produce real-world work product.
This is a great fit if you're a sharp, detail-oriented generalist who's comfortable moving across different formats and subject areas. You don't need deep specialization in any one field — strong judgment, careful reading, and clear written reasoning matter most.
