  • Partner with the product/engineering team to improve annotation tooling , dashboards, and automation.
  • Stakeholder Communication Serve as primary contact for internal teams needing labeled data (research, product, T&S, etc.).
  • Provide regular status updates : progress vs plan, blockers, quality metrics, and risks.
  • Gather feedback on label quality, edge cases, and evolving requirements; turn those into updated guidelines and processes .
