Why this role exists:
This role exists to protect our sportsbook ecosystem from financial leaks and sophisticated fraud. You’ll help us maintain platform integrity and profitability by analyzing real-time betting data, neutralizing risks, and catching vulnerabilities before they scale.
What you’ll drive:
Real-Time Detection & Monitoring
- Validate live deposit and withdrawal activity using internal monitoring tools and anti-fraud alert systems.
- Detect and intercept suspicious transaction patterns, including carding, money laundering (AML), account takeover (ATO), and payment method abuse.
- Analyze player behavior at the cashier level to uncover organized fraud rings and sophisticated bonus abuse linked to payment schemes.
Risk Decisions & Execution
- Apply immediate risk mitigation actions, independently triggering transaction holds, account freezes, and payment method restrictions.
- Drive KYC and EDD (Enhanced Due Diligence) requests for suspicious accounts to strictly validate player identities and source of funds.
- Manage and resolve complex chargeback disputes and internal JSM tickets related to financial suspicions without compromising operational SLAs.
Cross-team Collaboration & Process Improvement
- Partner with Compliance, Payments, and Finance teams to conduct deep-dive investigations into financial anomalies and potential security breaches.
- Document audit-ready case notes and maintain accurate internal tracking tables for all anti-fraud and payment actions.
- Optimize workflows by reporting bugs in payment logic, clarifying risk rules, and suggesting improvements to automated velocity checks.
What makes you a GR8 fit:
Must-have
- 1+ year of hands-on experience in payments fraud, risk operations, or financial crime monitoring (preferably in iGaming or FinTech).
- Strong understanding of payment ecosystem mechanics, including credit card processing, e-wallets, and chargeback lifecycles.
- Proven ability to make fast, autonomous decisions under time pressure with high operational accuracy.
- Readiness to work in a 24/7 environment on a structured 4/2 rotating shift schedule (morning, evening, and night shifts).
- Intermediate (B1+) English level to communicate clearly with international payment partners and maintain documentation.
- Native Ukrainian or Russian.
Nice-to-have
- Experience working with BI tools (like Tableau) or handling large transactional datasets.
- Familiarity with specialized fraud detection systems (e.g., SEON, Sift, or Accertify).
- Basic understanding of SQL for independent data validation and reporting.
