Equity Exotics Quant Modeller | 1st Line Challenge

A leading Tier 1 Investment Bank is seeking a Director-level Equities Exotics Modelling Quant to join its Equity & Hybrids team in London. Salary range £180k-£200k base plus bonus. This is a highly technical and hands-on role focused on complex and exotic equity pricing models (Local Vol, Stochastic Local Volatility, Local Correlation, Cliquets and cross-asset hybrids). The position is embedded within the equities quant function globally, providing expert model challenge and shaping submissions ahead of independent validation.

This will suit a senior quant modelling specialist who has actually built and calibrated complex equity exotics models and can intellectually challenge pricing frameworks because they understand them deeply. A real unique opportunity to become a platform-level modelling authority offering broader influence across the equities business. This role requires a true modelling specialist — not just governance oversight. Strong recent experience in Equity exotics is essential.

Full details of the Role:

• 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.

Key Responsibilities

• 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.

Candidate Profile

• 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.
