Social Media Content Evaluator

About the role

You will stand at the intersection of artificial intelligence and media analysis, helping to define how content is understood and categorized. Your work will directly influence the training data that powers models designed to interpret video, speech, and text. Every decision you make contributes to the creation of reliable, high-quality information sets used by researchers and engineers. You will own the entire lifecycle of evaluation for short-form video, from initial viewing through final classification. This position requires a deep commitment to accuracy and consistency in a fast-paced, detail-oriented environment. By validating language use within your native context, you ensure that the resulting datasets reflect real-world usage. Your role is essential for building trustworthy ground truth that can be scaled across global applications.
