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
