Vice President - Inflation Quant

Santander Corporate & Investment Banking (SCIB) is Santander's global division, supporting some of the world's most complex and sophisticated corporate and institutional clients with customised services and value-added wholesale products designed around their needs across Europe, US, Latam and Asian markets.

The Front Office Quant Team develops the pricing and risk models, production analytics and tools that support our Sales and Trading businesses. It is a highly respected, trading-aligned team that works side by side with traders and structurers in a dynamic, collaborative environment.

As an Inflation Quant in London, you will help shape the inflation curve and derivatives pricing libraries used by trading teams across SCIB's global platform—not only in London—while gaining broad exposure across the Rates business.

We are looking for a talented and motivated Quant who wants to see rigorous mathematical modelling translated into practical tools used at the trading desk. You will focus on the research, development, implementation and maintenance of pricing analytics and curve-construction frameworks for inflation derivatives, with particular emphasis on optionality, including caps/floors, Bermudan structures and path-dependent products.

This is a visible, high-impact role at the heart of research, trading and technology. It combines deep inflation modelling, broad Rates exposure, global desk interaction and hands-on development across Python, C++ and Rust. You will have the opportunity to take ownership of meaningful problems from initial research through to production implementation and desk adoption.

You will join at a pivotal stage in the evolution of our quantitative platform. This is a rare opportunity to review, redesign and migrate established Python and C++ libraries into a modern, purpose-built ecosystem spanning Python, Rust and C++.

You will play a key role in designing, building and maintaining the models and analytics across both the current and target platforms that support our inflation trading business. Your responsibilities will include:

• Designing, developing and maintaining models for inflation swaps, YoY and LPI structures, caps/floors, Bermudan options and other inflation-linked optionality
  , with related exposure to cash inflation instruments linkers / US TIPS
• Researching, developing and calibrating pricing models for inflation options, inflation cap/floor markets and related volatility analytics
• Developing and enhancing robust inflation curve-construction methodologies, including calibration, interpolation, extrapolation and the treatment of seasonality
• Building and improving production analytics for pricing, risk, calibration and scenario analysis across inflation and related Rates products, with a strong focus on accuracy, resilience and performance
• Developing practical modelling and pricing solutions for structured products with inflation components, working directly with Structuring and Trading from initial idea through to implementation
• Producing clear and rigorous model documentation and presenting methodologies, assumptions, limitations and results to traders, senior management and Model Validation
• Implementing, testing, optimising and supporting production analytics in libraries written in Python, C++ and Rust
  , helping move research efficiently from prototype to production while contributing to the modernisation of the wider quantitative platform

You will bring strong quantitative experience…
