Responsibilities
Build fraud detection models using gradient boosting and experiment with deep learning approaches where appropriate
Build supervised / unsupervised anomaly detection models on labeled and unlabeled data to identify outliers
Engineer features from transaction history, device fingerprints, behavioral signals, and identity data
Deploy models to production with real-time scoring and reason code generation
Design and execute champion/challenger experiments to validate model improvements
Build monitoring dashboards for model performance, drift detection, and feature stability
Analyze fraud patterns by corridor, customer segment, and transaction type to identify modeling opportunities
Investigate false positives and false negatives to drive continuous model improvement
Quantify trade-offs between approval rates and fraud losses at different threshold levels
Document model architecture, feature definitions, and performance characteristics
Support data labeling strategy and quality assurance with operations teams
Communicate insights and recommendations clearly to both technical and non-technical audiences
Qualification
Required
4+ years of experience in machine learning and data science
2+ years building production ML models in fraud, risk, payments, or financial services
Proven experience deploying and maintaining models in real-time production systems
Strong proficiency with gradient boosting frameworks (XGBoost, LightGBM, CatBoost)
Solid feature engineering skills—ability to extract signal from transactional and behavioral data
Production ML experience including model serialization, deployment, and performance monitoring
