Job Description
- Identify, extract, and engineer relevant features from diverse data sources (e.g., customer data, transaction data, behavioral data) to effectively discriminate between legitimate and fraudulent users.
- Conduct feature selection and dimensionality reduction techniques to optimize model performance and computational efficiency.
- Develop and implement advanced machine learning models (e.g., anomaly detection, supervised classification, time series analysis) to accurately detect and prevent fraudulent activities.
- Rigorously evaluate model performance using appropriate metrics (e.g., precision, recall, F1-score, AUC-ROC) and conduct A/B testing to validate effectiveness.
- Analyze raw data to uncover patterns, trends, and anomalies that may indicate fraudulent behavior.
- Generate actionable insights and recommendations to enhance fraud prevention strategies.
- Collaborate with engineering teams to deploy and operationalize developed models into production environments.
- Establish robust monitoring and alerting systems to track model performance, detect concept drift, and ensure ongoing effectiveness.
