  • Assess fraud-control effectiveness and provide recommendations for improvement.
  • Analyse customer friction metrics to balance fraud prevention objectives with customer experience.
  • Support remediation activities for emerging fraud risks and elevated loss trends.
  • Build and maintain dashboards using Looker, Power BI, Tableau, or similar analytics platforms.
  • Develop and optimize SQL queries for fraud, portfolio, compliance, and operational reporting.
  • Create recurring and ad hoc reports for Risk, Compliance, Product, and senior stakeholders.
  • Develop data visualizations that communicate actionable insights effectively.
  • Partner with Data Engineering teams to improve data quality, accessibility, and reporting capabilities.
  • Monitor portfolio performance against internal risk thresholds and payment network requirements.
  • Track fraud-to-sales ratios, chargeback ratios, dispute rates, approval rates, and transaction-risk indicators.
  • Analyze emerging payment-risk trends and provide early warning indicators to stakeholders.
  • Provide analytical support for fraud prevention, risk management, and portfolio optimization projects.
    • Requirements:
  • 4-7 years of experience in Fraud Analytics, Portfolio Analytics, Payments Risk, Financial Crime Analytics, Business Intelligence, or Data Analytics.
  • Strong analytical and problem-solving skills.
  • Experience working with large datasets and identifying actionable insights.
