Role Overview
This is a hands-on, full-cycle role that owns the whole fraud control loop: investigate, analyze, set up rules, monitor, and improve. You will work tickets daily, turn what you find into data-backed fraud rules and strategies, monitor how they perform, and keep refining them. Each stage feeds the next.
You will own the card risk control strategy, from set-up through ongoing performance, and be accountable for the fraud rate and the interception rate.
Key Responsibilities
1. Investigation
  • Handle card risk tickets daily: review rule-triggered alerts, investigate suspicious accounts and transactions, and decide on block, decline, step-up, or card-lifecycle actions within SLA
  • Investigate fraud typologies: account takeover, card testing, BIN attacks, merchant collusion, friendly fraud, and first-party abuse
  • Assess merchant and transaction risk by MCC risk type, including high-risk merchants and non-card payment flows
  • Manage disputes and chargebacks end to end under Visa/Mastercard rules: evidence, representation, pre-arbitration, and arbitration
2. Data Analysis
  • Turn investigation findings into patterns: analyze ticket, alert, and transaction data to identify fraud trends, attack vectors, and coverage gaps
  • Measure false positives against loss to judge whether existing rules are effective
3. Rule Set-up
  • Design and set up fraud rules, velocity limits, and strategies based on the analysis
  • Make sure rule triggers and decisions stay compliant; escalate linked AML/sanctions concerns to Compliance
4. Rule Monitoring
  • Continuously monitor alert and ticket data after rules go live
  • Track and report KPIs: fraud loss rate (bps), chargeback ratio, approval rate, alert handling time, recovery rate
  • Keep the programme within scheme monitoring thresholds (e.g. VAMP, ECM/EFM) and support scheme and partner audits
5. Rule Improvement
  • Adjust, retire, and add rules in response to monitoring results, balancing fraud loss against false positives and approval rate
  • Feed fraud trends back to Product and Engineering to improve onboarding, 3DS, and authorisation controls
Requirements
  • 3+ years in card fraud strategy or payments risk at an issuer, EMI, neobank, PSP, or card programme manager
  • Proven hands-on experience building and tuning fraud rules and strategies, not only working tickets
  • Hands-on knowledge of Visa and/or Mastercard dispute rules, reason codes, and chargeback timelines
  • Experience with MCC-based risk, high-risk merchants, and non-card payments
  • Strong data skills: SQL and Excel/Sheets to pull, slice, and explain fraud trends
  • Fluent English; Mandarin or other European languages are a plus
Nice to Have
  • Crypto-linked or prepaid/debit card programme experience, including crypto-to-fiat conversion at authorisation
  • Card risk control experience across multiple countries/regions
  • Experience launching a card programme in a new market or with a new BIN sponsor
  • Scheme monitoring programme remediation experience
  • Python or BI tooling (Looker, Tableau, Metabase)
  • Certifications: CFE, ACAMS, or equivalent
