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.
What you’ll do
Review and evaluate documents, slides, spreadsheets, and similar materials for quality and correctness
Provide clear, well-reasoned written feedback and ratings
Compare and rank AI-generated outputs against defined criteria
Flag errors, inconsistencies, and gaps in reasoning or formatting
What we’re looking for
Bachelor’s degree (minimum requirement)
Based in the UK or Europe
Excellent reading comprehension and written communication in English
Strong attention to detail and sound judgment across varied subject matter
Comfort working independently across common productivity tools (docs, slides, sheets)
No prior AI or machine-learning experience is required — we’ll provide the guidelines and context you need to succeed.
We consider all qualified applicants without regard to legally protected characteristics and provide reasonable accommodations upon request.
