This professional acts as the "human intelligence" required to train, validate, and refine Machine Learning (ML) models. By providing a deep understanding of content, this role ensures that AI applications—such as automated clipping, "chapters and topics" navigation, and scene-level brand suitability—are accurate, reliable, and contextually aware. You will focus on a deep understanding of video content to describe it accurately for AI systems, prioritizing content quality and descriptive accuracy over high-volume output. You will collaborate closely with ML data scientists to bridge the gap between creative content and technical model requirements. RESPONSIBILITIES: Identify and create high-quality, trusted "golden sets" of video data to serve as the ground truth for training robust AI models. Audit and validate ML model outputs to identify inaccuracies or "hallucinations," providing structured feedback to improve model performance. Analyze video to identify and timestamp significant events, such as award presentations, specific news topics, or sports highlights. Add detailed metadata and contextual information to video segments to improve discoverability and machine understanding. Work with engineering and product teams to
