STEM PhD Expert for AI Reasoning & Evaluation

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

• 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.
