  • 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
