Monzo is hiring a Credit Model Validation Manager to independently validate credit decisioning, machine-learning, statistical, and NPV/unit-economics models for its lending portfolio. The role provides second-line model-risk oversight, including model performance review, challenger-model development, framework enhancement, and clear reporting to governance committees. It requires deep credit-risk modelling knowledge, hands-on Python and SQL capability, and familiarity with underwriting scorecards, PD models, IFRS 9, stress testing, and lending strategy. The manager will partner closely with first-line credit modelling and strategy teams while providing constructive independent challenge. The position is based in London, Cardiff, or remotely within the UK, with occasional London meetings. ## Role DNA A quick view of the complexity, pace, ownership and collaboration implied by the job description. ### Job Complexity 5/5EasyHard ### Pace & Pressure 4/5RelaxedFast-paced ### Autonomy Level 5/5GuidedFull ownership ### Communication Load 5/5IndependentCollaborative AI insightThis is a senior, highly regulated financial-model-risk role requiring both technical depth in machine learning and credit modelling and independent judgment over material lending decisions.

I would assess conceptual soundness, variable selection, segmentation, assumptions, and training methodology; then independently test discrimination, calibration, stability, bias, and out-of-time performance. I would document limitations, compare results with policy and risk appetite, and recommend remediation or monitoring thresholds where needed. What is your approach to validating a machine-learning model used in real-time credit decisioning? I would evaluate whether the model is appropriate for the decision and whether its complexity is proportionate to the benefit over simpler alternatives. My validation would cover data quality, leakage controls, feature governance, explainability, robustness, fairness, latency, performance decay, and implementation consistency between development and production. I would also ensure there is effective monitoring, a clear escalation process, and a fallback approach if performance deteriorates. How would you use a challenger model in a validation exercise? I would build or select a suitably independent benchmark that is transparent and fit for the validation objective, such as a logistic-regression scorecard for comparison with a more complex ML model. The challenger would test whether key performance claims, feature relationships, segmentation choices, and commercial conclusions are robust. Differences would be investigated to determine whether they reflect genuine incremental value, overfitting, implementation issues, or unsupported assumptions. Describe how you would communicate a significant model weakness to stakeholders who developed the model. I would present the issue factually, clearly distinguish evidence from judgment, and link the weakness to customer, financial, regulatory, and risk impacts. I would explain the technical finding in plain language, show the relevant test results, and propose practical remediation options with priority and timelines. Maintaining a respectful, collaborative tone is important, but I would remain clear on the level of residual risk and required governance action. What would you review when assessing ongoing monitoring for an NPV or unit-economics model? I would review whether monitoring covers both predictive inputs and realised economic outcomes, including default, repayment, interest, fees, funding costs, collections, and customer-behaviour assumptions. I would test threshold design, segmentation, data timeliness, drift detection, overrides, and whether reported outcomes reconcile to the model's approved methodology. I would also assess whether breaches trigger timely investigation, escalation, and model recalibration or redevelopment.
