• Collaborate with data teams to build data infrastructure and early‑read monitoring and dashboards (first payment default, delinquency, vintage and roll rates) that help senior management understand credit risk trends and exposures
• Work with cross‑functional teams including DSML, Product, Design, Engineering, and Decision Platform to test and implement risk models and strategies in production, including accurate adverse action reasons
• Partner with Compliance, Legal, Fair Lending, Model Risk Management, Fraud, and our bank partners to document, approve, and govern credit policies
• Mentor and work collaboratively with other credit risk data scientists to develop strategies, share knowledge, and raise the team s analytical bar

• Excellent SQL and Python skills, advanced Microsoft Excel skills, and experience working in Looker or a similar business intelligence tool
• A strong grounding in statistics and machine learning for credit, including scorecards / gradient‑boosted models, swap‑set analysis, vintage analysis, and experiment design
• Hands‑on, detail‑oriented leader with exceptional communication skills who can explain a trade‑off to executives and defend the math behind it
• Ability to work in a fast‑paced, complex environment and meet ambitious deadlines while ensuring flawless completion
