Lead Generative AI Analyst

We are looking for highly detail-oriented Lead Generative AI Analyst to lead day-to-day execution of Chinese (zh-CN) multimedia and language data labeling and review work (e.g., video, images, and related metadata). This role serves as the primary liaison between annotators, quality stakeholders, and internal project teams, with accountability for throughput, quality performance, and guideline consistency.

• Track team performance and quality metrics (throughput, error rates, rework, backlog) and drive corrective actions
• Own calibration and consistency efforts across the team; reduce reviewer-to-reviewer variance through structured reviews and refreshers.
• Create, maintain, and improve guidelines and specifications; document edge cases and update instructions as workflows evolve.
• Establish and run quality workflows (sampling, second-pass review, audits) and ensure follow-up actions are completed.
• Coordinate across internal stakeholders and third-party partners as needed to meet delivery targets. Support onboarding and training for new annotators, including assessments and ongoing coaching. Maintain clear reporting on delivery status, risks, and blockers

• 2+ years of experience leading teams (people leadership, workflow leadership, or lead reviewer responsibilities).
• Demonstrated track record of delivering high-quality outputs on schedule in a production environment.
• Strong written and verbal communication in English, including the ability to write clear guidelines and provide actionable feedback.
• Experience working from structured guidelines and managing complex edge cases with consistent decision-making.
