At KBC we use a number of  models to support business decisions. These cover the domains of credit, markets, finance, treasury, asset management and insurance. This vacancy is for Interest Rate Risk in the Banking Book (IRRBB) models in the treasury context.  
 
As a Model Validator for IRRBB, your core responsibility is to validate models, both qualitatively and quantitatively. You critically assess their design, challenge assumptions, and verify their performance. The result? Stronger, more reliable models that support sound decision-making across the organisation.

  • You validate models, independently from a to z.
  • You present your findings to model owners, Chief Risk Officers and Chief Financial Officers. Based on your analyses and your knowledge of regulations and business practices you give substantiated answers to the questions ‘Can we use this model? Does it do what it is meant to?’
  • You are in frequent contact with colleagues in Belgium and abroad, and sometimes also external parties like auditors and regulators. So you build an interesting network.
  • You contribute to discussions regarding methodology.

  • You’re not afraid to ask critical questions and dive deep into challenging topics.
  • Giving clear advice on complex issues? No problem for you.
  • You like to work independently. Always with respect for deadlines.
