Equities & Hybrids Quant Modeller – Director
Location:
London (On-site)

A leading Tier 1 Investment Bank is seeking a Director-level Equities Quant to join its Equity & Hybrids team in London.

This is a highly visible role at the intersection of model development, governance and strategic oversight. You will provide senior technical leadership across complex equity derivatives models, ensuring robustness, transparency and strong model control standards.

You will work closely with Front Office quant teams developing and enhancing pricing and risk models across Equity and Hybrid products, particularly exotic derivatives. Acting as a senior technical authority, you will review and challenge model assumptions, guide enhancements, and help shape the overall modelling framework.

This role goes beyond pure model review — you will influence model standards, testing frameworks and governance practices across the function.

• Perform detailed technical reviews of complex equity and hybrid derivatives models
• Assess model assumptions, limitations and associated risk impacts
• Develop alternative models or benchmarking approaches where appropriate
• Specify, build and run analytical tests (primarily in Python; C++ exposure beneficial)
• Analyse results and clearly articulate findings to senior stakeholders
• Produce high-quality documentation aligned to internal governance standards
• Strengthen model testing coverage and promote automation where possible
• Partner with traders, strategists, developers and validation teams across the model lifecycle
• Contribute to broader strategic initiatives relating to model standards and controls
• Provide mentorship and technical guidance to less experienced quants

• PhD or Master’s degree in Financial Mathematics, Mathematics or Physics
• Significant experience developing and/or implementing Equity Derivatives models (hybrids advantageous)
• Strong knowledge of exotic derivatives modelling (equity preferred; other asset classes considered)
• Advanced Python skills; C++ beneficial
• Experience interacting with validation and control functions
• Exceptional attention to detail and high professional standards
• Strong communication skills with the ability to influence senior stakeholders

This is an opportunity to operate at Director level within a leading global investment bank, combining deep quantitative expertise with strategic influence across Front Office model development and governance.
