Mechanical engineering subject-matter work can help make AI training data more accurate and useful. Depending on the individual posting, tasks may involve applying engineering concepts and terminology while annotating content, reviewing model responses, evaluating technical information, or checking whether examples meet stated labeling guidance. Some assignments may also involve images, video, audio, text, or code when those materials relate to the project. Read each live posting carefully to understand the actual responsibilities and requirements for that role.
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. Because each project can have its own requirements, the individual live posting is the source of truth for the role’s eligibility, qualifications, responsibilities, and other terms.
