Vice President - Inflation Quant | SCIB

Join our community.

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.

The difference you’ll make:

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

What you’ll bring:

Our people are our greatest strength. Every individual contributes unique perspectives that make us stronger as a team and as an organisation. We’re enabling teams to go beyond by valuing who they are and empowering what they bring.

You will bring strong quantitative experience gained within a bank, asset manager, hedge fund or similar financial-markets environment, together with direct exposure to inflation products.

You will be a commercially minded Quant who enjoys working close to the trading desk and wants to see your work used in real pricing and risk decisions. You will combine strong mathematical modelling skills with the practical engineering judgement required to build reliable, production-quality analytics.

You will understand that the best front-office models balance mathematical sophistication with robustness, explainability, stability and performance. You will take ownership of problems, communicate clearly and work effectively with traders, structurers, quantitative developers, technology teams, risk managers and Model Validation.

Essential experience and skills include:

• An MSc, or equivalent, in Mathematics, Physics, Engineering, Computer Science, Quantitative Finance or another relevant quantitative discipline
• Professional experience developing pricing models for options and/or exotic derivatives within a financial institution, ideally in a Front Office Quant team working closely with Trading
• Strong knowledge of interest-rate and/or inflation derivatives modelling, together with a sound understanding of calibration and numerical techniques
• Practical experience in inflation and/or rates curve construction, including interpolation and calibration
• Excellent programming skills in Python and/or C++, with strong experience using scientific and numerical libraries such as NumPy, SciPy and pandas
• Familiarity with model-validation processes, model documentation, model-risk governance and relevant regulatory expectations
• Strong written and verbal communication skills, with the ability to explain complex modelling concepts clearly to both technical and non-technical stakeholders

Desired experience and skills are:

• A PhD in Mathematics, Physics, Engineering, Computer Science, Quantitative Finance or another relevant quantitative discipline
• Hands-on experience with products such as YoY options, LPI swaps, inflation caps/floors and Bermudan options
• Knowledge of cash inflation markets, including linkers and inflation-linked asset swaps, alongside derivatives experience
• Front Office Quant experience in inflation options and/or hybrid Rates–inflation models
• Professional experience using Rust within a large-scale quantitative or trading analytics ecosystem
• Experience with automated testing, continuous integration and deployment pipelines, version control and modern software-development practices

What else you need to know:

This role is based at our offices in Triton Square, London, within easy walking distance of Warren Street and Euston stations.

We want our people to thrive at work and at home, deliver the best outcomes for our customers and help one another develop.
