We're hiring PhD-level experts to help train and evaluate advanced AI models. This is remote, flexible contract work where your academic expertise directly shapes how cutting-edge models reason, answer, and improve. You'll review AI-generated content in your field, identify where the model gets things right or wrong, and help raise the quality bar on technical reasoning.

This is a short-term engagement running through the end of June, with potential to extend depending on project needs.

Key Responsibilities

You may contribute your expertise by:

  • Assessing the factuality and relevance of domain-specific text produced by AI models
  • Crafting and answering questions related to Machine Learning and AI
  • Evaluating and ranking domain-specific responses generated by AI models

What We're Looking For

  • A PhD (completed or in final stages) in one of the following fields: Machine Learning / AI, Computer Science, Engineering, Statistics, or a closely related quantitative subdomain such as Mathematics or Physics
  • Strong analytical and critical-thinking skills, with the ability to spot subtle errors in technical reasoning
  • Fluent written English and the ability to communicate complex ideas clearly

Nice to Have

  • Research experience (academic or industry)
  • Prior experience with data annotation or AI model evaluation
  • Experience reviewing or publishing research papers

Compensation

Up to $150/hr, depending on your area of expertise, depth of experience, and assessment performance.

Location

This role is fully remote. We are currently accepting applicants based in:

United States, Canada, Puerto Rico, Mexico, United Kingdom, Australia, New Zealand, and Argentina.
