Oversee and actively participate in labeling and reviewing tasks to maintain high standards and model best practices.
Ensure strict guideline adherence, taxonomy management, and quality assurance processes.
Drive efficiency by identifying and resolving operational bottlenecks, implementing process improvements, and tracking performance via KPI dashboards (e.g., quality metrics, throughput, send-back rates).

Collaborate closely with Human Data Managers, fellow Team Leads, and Engineering to translate model needs into clear labeling strategies and requirements.
Coach and develop talent while maintaining strong accountability and a high-performance culture; support disciplinary actions as needed.
Document outcomes, suggest process iterations, and report project status, risks, and results.
Act as the voice of your tutors while fostering strong collaboration across the broader Human Data organization.
