Amazon is looking for a Decision Scientist I to join 1P Lending team and help drive data-informed business decisions.
In this role, you will apply statistical modeling, machine learning, and experimentation techniques to solve well-defined problems across key business areas. You will build and validate models using standard methodologies (logistic regression, gradient boosting, survival analysis, classification), design and analyze A/B tests, and create metrics to quantify business impact. Working with large-scale datasets from multiple sources, you will partner with product, business, and engineering teams to translate data-driven insights into actionable strategies.

You will write mathematically rigorous documentation, follow best practices in model development, and deliver artifacts that directly improve business processes and customer outcomes.

Key job responsibilities
1. Build and validate statistical and machine learning models using standard methodologies (logistic regression, decision trees, random forests, gradient boosting, survival analysis).
2. Develop classification, regression, and segmentation models to support business decisions
Monitor deployed models for drift and degradation, and recommend recalibration when needed
Design, execute, and analyze A/B tests and controlled experiments to evaluate product and policy changes.
3. Drive end-to-end delivery of scalable data pipelines from ideation to production deployment.
4.



Gather and use large-scale datasets from multiple sources to build analytical solutions.
5. Write production-quality SQL and Python/R scripts to extract, transform, and analyze data at scale.
6. Create and maintain metrics and KPIs to quantify model performance and business improvement (e.g., AUC-ROC, precision-recall, Gini, KS statistic).
7. Partner with product, business, science, and engineering teams to translate complex analyses into actionable recommendations.
8. Write accurate, transparent, and mathematically rigorous technical documents, model documentation, and reports.
9. Conduct root cause analysis on business performance trends and anomalies.
10. Deliver artifacts for project components that improve processes or systems to inform business decisions.
11. Follow best practices to discover and adapt existing knowledge (internal and external research) to meet customer needs.
12. Understand what the team owns, including data pipelines, model infrastructure, and business impact.
