About the role

Key responsibilities & impact

Design and execute structured evaluation frameworks to assess the quality, coverage, and fraud-signal value of incoming data assets from vendor partners
Build lift analyses, backtests, and champion/challenger comparisons to quantify the incremental value of new data signals against our existing fraud detection stack
Profile vendor datasets for completeness, freshness, match rates, and population coverage across verticals (crypto, fintech, neobanks, e-commerce, etc.)
Collaborate with fraud leadership to define evaluation criteria tied to real fraud outcomes — false positive rates, catch rates, precision/recall tradeoffs
Translate vendor data findings into clear, actionable recommendations: adopt, pilot, deprioritize, or decline
Partner with data engineering to define ingestion requirements and ensure test environments reflect production-like conditions
Document evaluation results and maintain an internal knowledge base on vendor data performance over time
Support ad hoc deep dives into fraud trends, model performance, and client-specific data questions as needed

Solid understanding of evaluation metrics and statistical concepts: precision/recall, AUC/ROC, lift, population distributions, and A/B testing basics
Experience working with external or third-party datasets — assessing data quality, match rates, and signal value
Strong written and verbal communication skills; ability to synthesize complex analysis into clear narratives for non-technical stakeholders
