The Model Validation Group (MVG) is currently seeking a model validation analyst at Analyst or Senior Analyst level based out of our Toronto office.

The MVG is part of the Criteria Review and Approval Group which reports to the Chief Risk Officer. The core objective of the department is to ensure the quality and consistency of Fitch’s rating criteria and models. The MVG team focuses on reviewing and validating all models used in the credit rating analysis across Fitch Ratings and works closely with the Criteria Officers to review and approve criteria.

What We Offer:

Gain valuable credit modeling and validation experience, along with a good understanding of related credit products, their rating methodology, and criteria.
Develop a solid knowledge of model governance practices and the regulatory environment.

We’ll Count on You To:

Review and validate a wide range of credit rating models, such as default models, cashflow models, capital models, and regression models, covering asset classes including ABS, CMBS, Covered Bonds, RMBS, Structured Credit, Corporates, Financial Institutions, Insurance, and Sovereigns.
Review model codes and documentation, build replica models, design and execute comprehensive testing (conceptual soundness, performance/back-testing, sensitivity analysis, benchmarking).
Discuss review outcomes and observations with the model owners, developers, and Criteria Officers.
Write high-quality validation reports and memos aligning with internal standards and applicable regulatory expectations.
Contribute to enhancements in validation approaches, testing framework, and automation tools.

What You Need to Have:

Master's degree in quantitative disciplines or finance.
0-3 years of experience in financial modelling/analysis.
Capability to explain and communicate model review observations and model technical aspects clearly to technical and non-technical audiences.
Self-motivation with an ability to manage timelines across multiple projects.
Thorough attention to detail.
Strong work ethic.

What Would Make You Stand Out:

Demonstrated proficiency in programming in Python, R, VBA for quantitative statistical analysis. Familiarity with common libraries (e.g., pandas, NumPy/SciPy, scikit-learn) and Python object-oriented programming.
Previous exposure to credit rating analysis or cash flow modelling
Understanding of model risk management practices
A Certificate in Quantitative Finance (CQF)
