JT AI Labs is recruiting Statistics and Data Science experts to evaluate quantitative reasoning produced by AI models. You will assess statistical methods, identify flawed inference, test data interpretation quality, and provide expert feedback on whether a model's reasoning is genuinely sound or only superficially convincing.

This is remote, flexible, project-based work. No prior AI experience is required. We are looking for candidates who can spot weak methodology fast and explain why it fails.

Typical topics include probability, inference, regression, experimental design, causal reasoning, machine learning evaluation, and data interpretation.
