About the Role:
Responsibilities
- Lead the card-issuing risk control product architecture: Own the full lifecycle of the card issuing payment risk control product, building an end-to-end risk platform encompassing real-time authorization interception rules, static/dynamic limit systems, and abnormal transaction alerting mechanisms.
- Optimize rules and reduce false-positive rates: Continuously refine risk engine rules and threshold configurations to improve fraud detection quality while significantly reducing false-positive (false-decline) rates, balancing risk control red lines against payment approval rates.
- Build post-transaction monitoring and loss-prevention tools: Establish scalable post-transaction monitoring and manual review workflows; design authorization holds, offline force-debit protection, and settlement-cycle FX slippage prevention mechanisms.
- Design tiered and scenario-based controls: Tailor differentiated limit controls, 3DS verification strategies, and risk protection mechanisms for different user tiers, card types, and suspicious payment scenarios.
- Collaborate on risk operations and case efficiency: Work closely with the risk operations team to optimize alert routing, case management, and review/unblocking workflows, improving investigation and processing efficiency.
- Interface with card networks and BIN sponsors on compliance: Partner with data and engineering teams to ensure the stability of millisecond-level decision engines, ensuring the card portfolio's fraud rate complies with Visa/Mastercard and BIN Sponsor compliance and regulatory requirements.
- Enable AI and advanced analytics: Explore and apply AI and machine learning models to improve detection accuracy for complex fraud rings and anomalous transactions, reducing manual operational costs.
