Digital Controls & Innovation

• Design and implement digital controls and automated workflows to mitigate fraud impact
• Develop innovative analytical solutions to address emerging fraud schemes and attack vectors
• Create data-driven business rules and decision frameworks for fraud prevention
• Build monitoring systems and dashboards to track model performance and fraud trends

Research & Continuous Improvement

• Conduct time series analysis to identify seasonal fraud patterns, emerging trends, and change points in fraudulent activities
• Apply graph mining techniques to discover new fraud networks and relationship patterns
• Research and implement state-of-the-art anomaly detection methods for evolving fraud schemes
• Experiment with novel approaches including graph neural networks, temporal anomaly detection, and multivariate time series analysis
• Collaborate with business stakeholders to understand evolving fraud challenges

Collaboration & Communication

• Partner with claims, underwriting, and compliance teams to implement analytical solutions
• Present findings and recommendations to senior leadership and cross-functional teams
• Document methodologies, model logic, and analytical processes for regulatory compliance
• Contribute to team knowledge sharing and collaborative problem-solving
