• Assessment of the planned subscription business model from a fraud and chargeback perspective
• Identification of operational and technical risks
• Recommendations for reducing fraud and chargeback ratios

• Proven experience working with subscription/recurring billing merchants, including free trial, auto-renewal, and negative option billing models
• Hands-on experience building a VAMP rate calculation system (methodology, data sources, validation, reporting)
• Deep knowledge of Visa and Mastercard monitoring programs: VAMP, VDMP (Visa Dispute Monitoring Program), VFMP (Visa Fraud Monitoring Program), Mastercard ECM/EFM
• Understanding of the transaction and dispute lifecycle: authorization, clearing, chargeback, representment, pre-arbitration, arbitration
• Experience working with Visa and Mastercard reason codes, with a clear understanding of the differences between fraud and non-fraud disputes
• Knowledge of early warning and dispute prevention tools: Ethoca Alerts, Verifi CDRN, Verifi Order Insight, RDR (Rapid Dispute Resolution)
• Strong SQL and Excel skills for working with large transactional datasets
• Understanding of KYC, AML, and merchant underwriting principles in acquiring

Nice to Have

• Experience in international acquiring (cross-border, multi-currency)
• Experience integrating and configuring anti-fraud systems (3DS 2.x, device fingerprinting, behavioural analytics)
• Knowledge of PCI DSS and card data handling requirements
• Experience with BI tools (Tableau, Power BI, Looker) for building monitoring dashboards
• Experience working with card schemes on remediation programs

Personal Qualities

• Analytical mindset and strong attention to detail
• Ability to work with large datasets and identify patterns
• Proactive approach to risk identification and solution proposals
• Strong structured communication skills with business, operations teams, and card schemes
