About the Role
Senior Fraud Data Labeling Specialists are experienced contributors who not only perform complex data labeling tasks but also take expanded ownership over quality, process improvement, and cross-functional collaboration.

In this role, you will label high-impact datasets from customers, deliver consistently high-quality annotations, and help elevate labeling standards across the team. You will serve as a subject matter expert (SME) for fraud detection workflows, support audits and quality assurance efforts, and partner closely with Engineering, Product, and Operations to refine processes and improve model performance.

This role is ideal for someone who is highly detail-oriented, thrives in ambiguous and fast-evolving environments, and demonstrates strong ownership and leadership without direct authority.
