About AI Training Work

AI training is the human work behind modern artificial intelligence. People write, review, rate, and refine examples that help language models produce more accurate, useful, and reliable responses.

As an AI Rater Guidelines Writer, you will contribute at the instruction-design layer of this process. Your guidelines and rubrics will help human raters evaluate model outputs consistently, including when examples are ambiguous or difficult to classify.

• Work on cutting-edge generative AI and RLHF projects
• Help shape how advanced language models are evaluated
• Apply writing, reasoning, and domain-translation skills to practical AI development

The Role

OpenTrain AI is seeking an AI Rater Guidelines Writer to turn high-level, sometimes ambiguous program specifications into precise instructions for human raters. You will bridge program requirements and field application by creating clear, non-contradictory guidelines that support consistent decisions across diverse subject-matter domains.

This is a part-time contractor opportunity for applicants in the United States who work in English. The listed rate is $45-$65 per hour.

Requirements

This role requires professional experience developing clear written guidance and direct experience supporting human rating in a generative AI or RLHF environment. You should be comfortable identifying ambiguity, resolving contradictions, and explaining complex requirements in straightforward language.
