What you will do… Rules engine strategy and ownership Author complex, multi-factor fraud rules (e.g., using FICO Falcon, Actimize, Sardine, etc.) that evaluate 200+ data points per transaction, including merchant category, velocity, IP reputation, and behavioral biometrics. Manage the constant lifecycle of a rule. Proactively audit the legacy ruleset to retire stale logic that no longer catches fraud but still adds latency or causes false positives. Identify and resolve rule overlap where multiple rules trigger on the same pattern, ensuring the decisioning engine remains lean and fast. Champion-challenger testing and simulation Before any new rule goes live, it must be tested in shadow mode, testing it against 30 days of real historical traffic to predict exactly how many good users it would have blocked. Justify every new rule with a data-backed cost-benefit analysis. Rather than static rules, write dynamic and adaptive rules that adjust thresholds based on the user’s individual behavior. Data forensics and emerging pattern detection Use SQL and Python to perform cluster analysis. For example, if three cards are used at the same digital merchant within 5 minutes, one must identify if this is a carding attack and write a temporary circuit breaker rule immediately. Link data from EWA transfers, direct deposits, and card swipes to identify account takeovers (ATO). Incorporate external merchant risk data to write rules that are stricter at high-risk digital goods stores but leaner at local grocery stores. Performance tuning and KPI accountability Optimize false positive ratio and keep it below mandated threshold. If fraud losses spike in a specific category (like Travel or Fast Food), pivot the strategy within hours to close the gap. Ensure rules don’t accidentally decline high value transactions that generate significant interchange revenue unless the risk score is undeniably high.
