• Assist in development, validation, and maintenance of real-time features.
• Design, build, evaluate, and defend machine learning models to predict fraud risk.
• Build efficient and reusable data pipelines for feature generation, model development, scoring, and reporting using Python and SQL.
• Deploy models in a production environment in collaboration with other data scientists and engineering teams.
• Collaborate with business partners to create policies utilizing model results.
• Implement metrics like AUC, KS, and Gini to monitor/measure model performance, and PSI/CSI to measure stability indices.
• Ensure model fairness, interpretability, and compliance with FCRA, ECOA, and other relevant regulatory frameworks.

Required Skills & Experience:

We are looking for someone with a proven track record of successful contract engagements. The ideal candidate will have:

• 2+ years of industrial experience in Data Science, Machine Learning, and related areas.
