Model Risk Validator
Jobs UK — 2026 Career Guide
Model Risk Validation is the most in-demand hidden AI career in UK finance. With the PRA's SS1/23 supervisory statement now in force, every regulated bank must have independent model validation — and the demand for qualified MRV professionals is outpacing supply. This guide covers what the role involves, what it pays, and how to get hired.
What Does a Model Risk Validator Do?
Model Risk Management (MRM) is the independent function within a financial institution responsible for identifying, assessing, and mitigating the risks that arise from using models in decision-making. A Model Risk Validator sits within this function, performing independent technical reviews of models built and used by the business.
The scope of models subject to validation is broad: credit scoring models, market risk models (VaR, CVA), fraud detection ML models, anti-money laundering surveillance models, algorithmic trading models, capital stress testing models, and increasingly LLM-based tools used in financial decision support. Any model used for regulatory capital calculations or significant business decisions requires documented independent validation.
A typical Model Risk Validator's responsibilities include: reviewing model design documentation, independently replicating model results using the stated methodology, testing model assumptions (often by deliberately violating them), assessing model performance on out-of-sample data, stress testing behaviour under extreme scenarios, benchmarking against alternative approaches, and producing written validation reports that summarise findings and residual risks.
The outputs of validation feed directly into Model Risk Committees and Boards — and are reviewed by the PRA, FCA, and US Federal Reserve during regulatory examinations. This gives MRV work unusually high visibility within the organisation.

Key Skills for Model Risk Validators
Regulatory Knowledge (SS1/23, SR 11-7)
The PRA's SS1/23 and US Federal Reserve's SR 11-7 are the core regulatory frameworks. Understanding what they require for validation documentation, independence, and tiering is essential.
Python and/or R
For independently replicating model results and running your own validation tests. Python is more common at tech-forward banks; R is still widely used in actuarial and statistical MRM functions.
Statistical Modelling
Regression, classification, time-series analysis, and hypothesis testing. You need to understand what the model is doing deeply enough to independently challenge its assumptions.
ML / AI Model Familiarity
Gradient boosting, neural networks, NLP models. Increasingly required as banks validate AI/ML models rather than purely statistical ones. SHAP and LIME for explainability.
Credit Risk Fundamentals
For validating credit models (PD, LGD, EAD) — understanding credit scoring, IFRS 9, and the Basel framework is required at most banks.
Technical Writing
Model validation reports are formal documents reviewed by regulators. Clear, precise technical writing is a critical skill — often underemphasised in job descriptions.
Market Risk (VaR, Greeks)
For validating trading and market risk models at investment banks. Black-Scholes, Monte Carlo, sensitivity analysis.
Model Performance Metrics
Gini, KS statistic, PSI, Hosmer-Lemeshow for credit models. RMSE, MAE, Sharpe ratio for other model types. PSI for monitoring model stability.
Career Progression for Model Risk Validators
Junior MRM Analyst
Supporting validation of simpler models (scorecard, logistic regression), learning the regulatory framework, and building your understanding of the bank's model inventory. Typically working closely with senior validators on complex model reviews.
MRM Analyst / AVP
Leading validation of mid-complexity models independently. Owning your validation reports from scoping to sign-off. Building domain specialisation (credit, market risk, or AI/ML models).
Senior Validator / VP
Validating complex models including AI/ML systems and regulatory capital models. Leading small teams on large validations. Engaging directly with regulators during examinations. Managing model risk for a portfolio of models.
Head of Model Risk / Director
Setting MRM strategy for a business or the whole institution. Managing the MRM function, owning the model inventory policy, and acting as the primary point of contact for PRA/FCA examinations. Reporting to the CRO.

Frequently Asked Questions
What does a Model Risk Validator do at a UK bank?
Independently challenges and validates AI and statistical models used in financial decision-making — reviewing design, testing assumptions, checking data quality, stress testing, and producing validation reports for risk committees. The role sits in MRM — separate from development teams.
What is SS1/23 and why does it matter?
SS1/23 is the UK PRA's supervisory statement on model risk management (effective May 2024). It sets out expectations for governing, developing, validating, and using models — including AI/ML. MRV work must demonstrate SS1/23 compliance. US SR 11-7 is the equivalent for US-owned banks.
What salary can a Model Risk Validator expect?
Junior/analyst level: £55,000–£80,000. Mid level (AVP/VP): £80,000–£120,000. Senior (Director/MD): £120,000–£175,000+. At bulge-bracket banks, total comp including bonus is 30–80% above base.
Do you need a PhD?
A PhD in a quantitative discipline is highly valued at bulge-bracket banks but not always required. An MSc plus several years of quant modelling experience is a viable route. Strong Python/R skills and regulatory knowledge (SS1/23) are the core requirements.
Which UK banks have the strongest model risk functions?
Goldman Sachs, JP Morgan, Morgan Stanley, HSBC, Barclays, and Standard Chartered all have large MRM functions in the UK. The function has grown significantly since SS1/23, as all regulated firms must demonstrate independent model validation.
