Junior Data Scientist, AI Evaluation

The Work

You will assess AI-generated answers to problems in data science, statistics, machine learning, experimentation, and quantitative reasoning. Your reviews will help identify weak methods, statistical errors, and unsupported conclusions.

You will also create prompts and datasets that test analytical reasoning, develop reference solutions, and write structured feedback to improve model accuracy and usefulness.

About AI Training Work

AI training is the human work behind many AI systems. People review model answers, create examples, and give feedback so models produce more accurate and useful results. Experience in fields such as statistics, machine learning, and data science is valuable because it helps reviewers judge technical reasoning carefully.
