About your role: In this role, you'll work at the intersection of fraud prevention, billing, and payment operations across multiple web products with monthly volumes of up to $1M. You'll take part in building an anti-fraud system from scratch — from selecting and implementing the tool to writing rules and monitoring, handle chargebacks and alerts, and sync anti-fraud filters with the payment orchestrator.
This is an opportunity for a billing/fraud specialist to gain full ownership of the anti-fraud function within an international product, work with tools like SEON and Merchanto, and see the direct impact of your work on chargeback rates and the overall financial health of the products.
In this role, you will
- Implement the anti-fraud tool across all products, build and maintain rules to ensure their effective performance
- Handle billing-related customer requests via support lines, resolving issues professionally and efficiently
- Collect and analyze information with high attention to detail when making decisions with financial impact or working with customer payments
- Manage risks: prevent chargebacks and fraud, monitor VAMP & ECM ratios, and maintain ongoing transaction monitoring
- Work with alert systems and process alerts through PSP and acquirer partner dashboards; resolve disputes with customers or banks that have filed chargeback requests
- Sync anti-fraud tool rules with the payment orchestrator to ensure filters work in harmony without conflicting, and monitor traffic drop-off caused by overlapping anti-fraud logic
It’s all about you
- 2+ years in billing/payment operations or fraud/risk management (payment operations: chargebacks, disputes, fraud monitoring as your primary focus)
- Hands-on experience with the full chargeback management cycle — alerts (Ethoca/Verifi) via third-party services such as Chargebackhelp, SEON, Merchanto, Disputer, or Dispu
- Practical experience with anti-fraud tools — SEON, Sift, Riskified, Kount, Feedzai, Forter, or similar — with a solid understanding of rule configuration
- Understanding of card scheme dispute programs: Visa VDMP/VFMP, Mastercard ECM; familiarity with reason codes, escalation stages, and what it means to enter a monitoring program and why it matters
- Analytical skills and confidence in identifying patterns in approval rates, decline reasons, and fraud trends
- Upper-Intermediate written English
- Proactive approach, ability to work both autonomously and as part of a team
Would be a plus
- Experience with Tableau, Superset, or Looker
- Effective use of AI tools in day-to-day work
