- Configure and tune rules, thresholds, and predictive models within the fraud risk engine to enable real-time decisioning.
- Translate business needs into statistical or machine learning models. Validate and monitor model performance, ensuring alignment with governance standards.
- Ensure fraud decisions are accurate, timely, and actionable. Design alerting mechanisms that balance fraud prevention with customer experience.
- Present analytical findings and model outcomes to technical and non-technical stakeholders. Provide recommendations for continuous improvement.
