About The Position

Establish and maintain standards for the development of models used in Wholesale Credit loan loss forecasting and Obligor Grading. Enhance these standards in accordance with evolving industry practices and regulatory expectations. Evaluate the adherence of model development processes to established standards by assessing the soundness of model design, validity of assumptions, reliability of input data, thoroughness of testing and implementation, and the appropriateness of performance metrics for Wholesale Credit loan loss forecasting and Obligor Grading models. Perform model reviews by identifying weaknesses, limitations, and emerging risks through techniques including benchmarking, independent testing, and continuous monitoring activities. Prepare detailed technical documentation and reports outlining model risk assessments and communicate findings and recommendations to internal stakeholders and senior management. Support the organization in ensuring appropriate use of models on an ongoing basis and contribute to maintaining the overall model risk within the firm's risk appetite framework. Participate in internal and external audits, as well as regulatory examinations related to model risk governance and compliance.
