Credit Model Validation Manager

Monzo is looking for a Credit Model Validation Manager to join its second line of defence team as its lending business grows. The team gives independent oversight and challenge to the people who build Monzo's credit models, making sure those models are fit for purpose, well governed and deliver good outcomes for customers.

• Review and challenge impairment adequacy, ICAAP and stress testing assessments
• Review ongoing model performance monitoring and support first line teams
• Run statistical analysis, model replication and challenger work
• Help improve the Model Risk Framework and build reusable, AI-assisted validation tools
• Write validation reports and present findings to committees

What they ask for:

• Practical experience developing or validating credit models, including IFRS 9, IRB or other capital models
• A solid understanding of model risk management and regulatory expectations
• Strong SQL and Python, with clean, tested, version-controlled code
• Clear communication with non-experts and the confidence to give respectful challenge
