Data Validation Specialist

The Data Validation Specialist checks that data entering and moving through our systems is accurate, complete, and consistent. The Data Validation Specialist is responsible for labeling, tagging, categorizing, and reviewing large volumes of structured and unstructured data (text, images, audio, video, or multimodal content) according to detailed project guidelines. This role also validates work completed by other annotators, identifies inconsistencies or errors, and provides feedback to improve annotation quality and guideline clarity. The ideal candidate is meticulous, comfortable with repetitive, detail-oriented work, able to follow complex and evolving instructions precisely, and confident flagging ambiguity rather than guessing. As a flex position, the role scales hours up during peak periods such as new AI model launches and down when volume is lower. Assignments are checked to verify progress, through a reporting mechanism by the Artificial Intelligence Project Manager.
