Statistics subject-matter work can bring careful quantitative judgment to AI-training projects. A role may involve reviewing whether an AI response interprets data correctly, assessing reasoning that uses statistical concepts, labeling examples for model development, or evaluating the quality of data-related outputs. Some projects may also involve reviewing search results, written responses, or code where statistical understanding is relevant. The individual posting explains the actual responsibilities, so read it closely before deciding whether a role matches your background.
OpenTrain hires for the public roles available through OpenTrain. Candidates apply through OpenTrain, and successful candidates may be placed or referred to the client whose project they will support.
