Why this role exists:

This role exists to protect sportsbook margin and safeguard our betting ecosystem against real-time operational risk and targeted sports fraud. You’ll help us maintain high-velocity platform integrity by identifying sophisticated exploitation, executing precise risk mitigations under tight SLAs, and fine-tuning automated risk controls.

What you’ll drive:

Monitoring & Fraud Discovery

• Monitor real-time risk signals and betting velocity across pre-match and live sports markets to detect arbitrage, latency exploitation, late lines, and syndicate activity.
• Investigate complex account networks by linking bet patterns, timing, odds anomalies, device fingerprints, IPs, and payment trails.
• Analyze suspicious fixtures and irregular betting volumes to isolate systemic manipulation and potential match-fixing from organic player action.
• Differentiate high-volume winners from fraudulent abusers, ensuring commercial profitability while protecting VIP experience from unjustified restrictions.

Risk Decisions & Operational Execution

• Execute calibrated risk interventions—including sports segmentation, stake limits, delay adjustments, and settlement blocks—within approved operational authority.
• Process technical refunds and manual bet recalculations swiftly when third-party data feeds, line drops, or settlement engines encounter edge-case errors.
• Manage critical incidents and mass alerts during high-profile sporting events, triaging financial exposure under high concurrency and strict time constraints.
• Maintain audit-ready case files, structured tags, and detailed shift logs so that cross-shift investigations never lose operational context.

Cross-Team Alignment & Stakeholder Collaboration

• Partner directly with Trading and Sport Integrity teams to align on margin targets, line discrepancies, market suspensions, and external integrity alerts.
• Manage operational tickets through Jira/Service Desk, resolving risk queries within strict response-time SLAs.
• Coordinate with sports data providers during external investigations requiring upstream event validation or official result verification.

Optimization & Tool Evolution

• Validate new risk algorithms and automated detection rules, participating in UAT to minimize false positives and repetitive manual workflows.
• Pinpoint system edge-cases and detection gaps, submitting reproducible bug reports and clear functional requirements for internal risk tooling.
• Mentor junior specialists and document standard operating procedures in our shared knowledge base to elevate shift performance.

What makes you a GR8 fit:

Must-have

• 1+ years of hands-on experience in sportsbook risk operations, sports trading, antifraud, or integrity analysis.
• Deep fluency in sports betting mechanics: market pricing, Asian lines, parlay settlements, margin calculations, and typical exploitation vectors (e.g., latency, arbitrage, steam).
• Demonstrated track record of independent risk triage, including managing back-office risk configurations (segments, delays, limits, manual resettlements).
• Operational stamina: Proven ability to prioritize calmly and execute accurate financial interventions during high-volume live event incidents.
• Fluency in Ukrainian and Russian, alongside Intermediate English or higher for platform systems, documentation, and engineering communication.

Nice-to-have

• Experience configuring alert rules or running acceptance testing for internal risk/fraud prevention tooling.
• Exposure to query/visualization tools (e.g., SQL, Tableau, Power BI) for analyzing GGR trends and false-positive alert ratios.
• Academic background in Finance, Economics, Statistics, IT, or Sports Management.
