Job Summary (List Format) – Credit Risk Data Scientist
Design, build, evaluate, and defend machine learning models to predict credit risk for short-term lending products (e.g., tax refund advances, BNPL, installment loans).
Collaborate with product and risk teams to align models with business goals and drive actionable lending decisions.
Develop efficient and reusable data pipelines for feature generation, model development, scoring, and reporting using Python, SQL, and CK ML/AI infrastructure.
Deploy models to production in collaboration with data science and engineering teams.
Partner with business stakeholders to create policies based on model results.
Implement and monitor model performance metrics (AUC, KS, Gini) and stability indices (PSI, CSI).
Ensure model fairness, interpretability, and compliance with relevant regulatory frameworks (FCRA, ECOA).
Utilize expertise in Python (scikit-learn, XGBoost, LightGBM, pandas, numpy) and SQL for large-scale data processing.
Apply advanced machine learning techniques (tree-based models, regression, time series, causal analysis, clustering) to solve credit risk problems.
Analyze and interpret large, complex datasets to extract actionable insights.
Leverage deep understanding of credit risk modeling concepts (PD calibration, reject inference, adverse action logic, risk segmentation).
Work with tax and/or credit bureau data (e.g., TransUnion, Experian, Equifax) in credit model development.
Incorporate cash flow data and other alternative data sources into credit risk models.
Demonstrate strong business problem-solving, communication, and collaboration skills.
Requires a degree in Mathematics, Statistics, Computer Science, or related field, and at least 2+ years’ experience in Data Science, Machine Learning, and credit risk/lending/fintech domains.
Overall 9+ years of relevant professional experience required.
