Quant / Risk modeler: developing, calibrating and validating models
A quant or risk modeler develops, calibrates and validates the quantitative models that underpin capital and valuation decisions: VaR, Expected Shortfall, XVA, PD/LGD. They work under a model governance framework that requires documentation, independent validation and, where AI components are involved, controls under ISO 42001.
What they do / responsibilities
- Model development — builds the market, credit and counterparty risk models: VaR, Expected Shortfall, XVA, PD/LGD, pricing models.
- Calibration — fits parameters to market and historical data and documents the assumptions and their limits of validity.
- Validation and independence — subjects the model to independent validation, backtesting and sensitivity analysis before production use.
- Documentation and governance — produces the documentation required by the model risk management framework (SR 11-7) and maintains the model inventory.
- Governance of AI components — when the model incorporates machine learning, applies management controls under ISO 42001.
Why it is scarce / why it matters in banking
The risk modeler combines statistics and numerical methods with a deep understanding of the financial product and the regulatory framework. The scarcity stems from that dual demand: few profiles master both the quantitative technique and the model governance discipline the supervisor expects. In banking and insurance, models determine regulatory capital, provisions and the price of risk; a poorly calibrated or insufficiently validated model translates into losses, sanctions or incorrect capital consumption. The Federal Reserve's SR 11-7 framework set the reference standard for managing that model risk.
