Senior Model Validation Quantitative Analyst - Quanteam in London

We are seeking a Senior Model Validation Quantitative Analyst to provide independent review and challenge of quantitative models used across risk, pricing, capital, and stress testing. The role sits within the Model Risk / Quantitative Analytics function and plays a critical part in ensuring models are theoretically sound, well-implemented, and compliant with regulatory expectations. You will work closely with model developers, risk stakeholders, and governance committees, contributing to robust model risk management across the firm.

Key Responsibilities

• Perform end-to-end independent validation of quantitative models, including:
• Conceptual soundness and theoretical foundations
• Assumptions, limitations, and appropriateness of use
• Empirical testing, benchmarking, and sensitivity analysis
• Validate models across areas such as market risk, credit risk, capital, stress testing, and pricing (scope depending on experience).
• Review model implementation (code, calculations, data usage) and identify model risk issues.
• Produce clear, well-structured validation reports for senior governance forums.
• Provide constructive challenge to model developers and propose remediation actions.
• Support regulatory reviews, internal audits, and ongoing model governance activities.
• Contribute to the continuous improvement of model validation standards and methodologies.

Who We’re Looking For – Technical Expertise

• Strong academic background in mathematics, statistics, econometrics, physics, engineering, or quantitative finance.
• Solid experience in model validation, quantitative analytics, or model risk management within banking, consultancy, or financial services.
• Strong understanding of:
• Statistical modelling and time-series analysis
• Risk modelling frameworks (e.g. VaR, stress testing, PD/LGD, capital models)
• Proficiency in Python, R, or similar quantitative programming languages; ability to review and challenge model code.
• Familiarity with model risk governance and regulatory expectations (e.g. SR 11-7, ECB, PRA, Basel).
• Ability to independently design validation tests and benchmarks.

Who We’re Looking For – Behavioural Traits

• Intellectually curious with a strong instinct to challenge assumptions and dig into model behaviour.
• Confident but collaborative, able to engage constructively with model developers and senior stakeholders.
• Clear and concise communicator, capable of translating complex quantitative topics for non-technical audiences.
• High standards of professional judgement, independence, and integrity.
• Well-organised, resilient, and comfortable managing multiple model reviews in parallel.
• Motivated to develop technical depth while contributing to broader model risk strategy.
