Day to day, responsibilities include:

• Deliver in-depth theoretical assessments of pricing models across various asset classes.

• Independently benchmark Front Office pricing models using C++ and Python.

• Perform qualitative analyses and stress tests to measure model performance.

• Compile comprehensive validation reports that clearly detail your findings and recommendations.

• Develop, enhance, and maintain internal tools that support and streamline the model validation process, contributing to the team’s overall efficiency and impact.

Why join us?

What we’re looking for?

• A Master’s degree or higher in a quantitative discipline (e.g., Mathematics, Physics, Quantitative Finance) or equivalent experience in a quantitative role.

• A solid theoretical understanding of, and familiarity with, derivative pricing models, stochastic calculus, partial differential equations and Monte Carlo methods.

• Excellent problem-solving and time management skills.

• Strong written and verbal communication skills, with the ability to articulate complex mathematical concepts clearly and concisely.

• The ability to work independently, meet deadlines, and perform well under time pressure.

And any experience of these would be great

• Prior experience in a Model Validation or Front Office Quant role.

• Programming experience in C++ and/or Python including library architecture design.

• Strong understanding of financial derivatives and risk modelling.

• Ability to critically evaluate model performance and identify limitations.

• Familiarity with regulatory expectations related to model risk.
