About This Position

The role involves developing advanced fraud detection solutions using machine learning and data science techniques. Responsibilities include building models with gradient boosting and exploring deep learning approaches, designing supervised and unsupervised anomaly detection systems, and engineering features from transactional, behavioral, and identity data. The position requires deploying models into real-time production environments with scoring and explainability, conducting champion/challenger experiments, and creating monitoring dashboards for performance, drift detection, and feature stability.

The individual will analyze fraud patterns across corridors, customer segments, and transaction types, investigate false positives and negatives, and optimize trade-offs between approval rates and fraud losses. Additional duties include documenting model architecture and performance, supporting data labeling strategies, and communicating insights to both technical and non-technical audiences.

What You Will Do:

* 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

Who We're Looking For:

Experience

* 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

Technical Skills

* Strong proficiency with gradient boosting frameworks (XGBoost, Light

GBM, Cat Boost)

* Solid feature engineering skills-ability to extract signal from transactional and behavioral data

* Production ML experience including model serialization, deployment, and performance monitoring

* Proficient SQL for working with large datasets (Big Query, Snowflake, or similar)

* Proficiency in Python: pandas, Num Py, scikit-learn, and familiarity with deployment tools

* Understanding of model explainability (SHAP values, feature importance, gain importance)

* Experience with A/B testing or champion/challenger experimental design

Domain Knowledge

* Understanding of fraud detection concepts: false positive/negative trade-offs, precision/recall, threshold optimization

* Familiarity with common fraud signals (velocity, device, identity, behavioral)

* Ability to translate model outputs into business impact (approval rates, loss rates, customer friction)

Preferred

* Experience with payment fraud, account takeover, or identity fraud specifically

* Familiarity…
