You will set high standards of technical excellence, exercise sound judgement, and foster strong, effective engagement with stakeholders across the Group.

Your core responsibilities will include

• Model Validation & Technical Leadership – Lead the design and execution of comprehensive validation plans assessing data quality, modelling methodologies, model performance and regulatory compliance.
