Partner with first-line credit strategy teams and wider risk teams to embed consistent validation standards.
Embrace innovative technology by adopting AI tools to improve the overall validation approach.

Requirements

Extensive practical experience in credit model development or validation within financial services.
Strong background working with machine learning or statistical models used in credit decisioning, such as origination PD models, underwriting scorecards, and NPV or unit economics models.
Deep understanding of statistical techniques for credit and model risk.
Familiarity with how models function in real-time lending strategies and how to balance risk versus commercial outcomes.
