• Monitor model performance, diagnose prediction errors, and continuously improve model quality

• Build and maintain datasets and features, and support A/B test analysis and statistical interpretation

• Bring models from research to scheduled production calculations and gradually expand modeling to other areas, including risk models

Nice to have

• Experience with subscription-based products, recurring billing, and payment data
