Job description

We're looking for US or Canada-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 is 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 United States or Canada
• 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.
