As Card Product Manager, you will own the full lifecycle of the card issuing payment risk control product. This is a complex, high-impact role requiring you to build an end-to-end risk platform encompassing real-time authorization interception rules, static/dynamic limit systems, and abnormal transaction alerting mechanisms.
Key responsibilities include:
- Continuously refine risk engine rules and threshold configurations to improve fraud detection while reducing false-positive rates, balancing risk control against payment approval rates
- Establish scalable post-transaction monitoring and manual review workflows; design authorization holds, offline force-debit protection, and settlement-cycle FX slippage prevention
- Tailor differentiated limit controls, 3DS verification strategies, and risk protection mechanisms for different user tiers, card types, and suspicious payment scenarios
- Work closely with risk operations to optimize alert routing, case management, and review workflows
- Partner with data and engineering teams to ensure millisecond-level decision engine stability and compliance with Visa/Mastercard and BIN Sponsor requirements
- Explore and apply AI/ML models to improve detection accuracy for complex fraud rings and anomalous transactions
You will need 3+ years of experience in payment risk control, card issuing systems, or digital banking product management, with demonstrated experience in card issuing risk control, real-time authorization interception, limit management, or loss prevention. Strong data-driven mindset with SQL and data analysis proficiency is essential. You must excel at cross-functional collaboration with risk operations, compliance, data analytics, and engineering teams. Experience with crypto cards, Web3 payments, or building card issuing systems from 0 to 1 is highly valued.
