Associate/Vice President - Inflation Quant | SCIB

We are looking for a talented and motivated Inflation Quantitative Analyst to join our Quantitative Products team. The successful candidate will focus on the development, implementation, and maintenance of pricing analytics and curve construction frameworks for inflation products, with a particular emphasis on inflation options, caps/floors, and volatility products. This is a high-impact role working at the intersection of research, technology, and trading.

Responsibilities

• Designing, developing, and maintaining models and analytics for inflation derivatives, including inflation revenue swaps, year‑on‑year swaps, LPI swaps, caps/floors, and inflation‑linked optionality.
• Developing and enhancing inflation curve construction methodologies, including bootstrapping, interpolation, extrapolation, and seasonality‑adjusted curves.
• Building and improving analytics for pricing, risk, calibration, and scenario analytics for inflation and rates products.
• Supporting the development of pricing and/or calibration models for inflation options, inflation cap/floor markets, and related volatility analytics.
• Working closely with inflation traders, structurers, and risk managers to ensure models and curves are accurate, robust, performant, and fit for purpose.
• Implementing and testing new models within production analytics libraries using Python, C++, and/or Rust.
• Monitoring and improving the performance, stability, and accuracy of existing analytics, resolving production issues in a timely manner.
• Producing clear model documentation and presenting methodology, assumptions, and results to traders, senior quants, and model risk stakeholders.
• Staying current with academic literature, market practice, and regulatory expectations in inflation modelling, calibration, and pricing.

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 be a commercially minded quant who enjoys working close to the trading desk. You combine strong mathematical modelling skills with practical implementation ability and a clear understanding of how models are used in production trading environments. You should be comfortable balancing model sophistication with robustness, explainability, and performance. You will be proactive, collaborative, and able to work effectively with traders, structurers, developers, risk managers, and model validation teams. You will play a key role in designing, building, and maintaining models and analytics for inflation derivatives trading.

Qualifications

• Extensive quantitative experience gained in a bank, asset manager, hedge fund, or similar financial markets environment, with direct exposure to inflation products.
• Professional quant experience with options modelling, ideally in a front‑office or trading‑aligned environment.
• A higher qualification in Financial Mathematics, Engineering, Applied Mathematics, Physics, Computer Science, or a relevant mathematical based degree.
• Excellent knowledge of interest rate and inflation derivatives modelling, ideally with experience in inflation options, inflation caps/floors, or related rates volatility products.
• Experience in inflation/rates curve construction, bootstrapping, interpolation, seasonality adjustments, and calibration techniques.
• Excellent programming skills in Python and/or C++ are essential, with deep experience in numerical libraries (e.g., NumPy, SciPy, pandas).
• Familiarity with model validation processes, model documentation, and regulatory requirements relating to model risk.
• Experience with automated testing, CI/CD pipelines, and version control such as Git.
• Well‑developed communication skills, with the ability to explain complex modelling concepts clearly to both technical and non‑technical stakeholders.
• PhD in Financial Math, Engineering, Applied Mathematics, Physics, Computer Science, or a relevant mathematical based discipline.
• Hands‑on experience with products such as YoY swaps, revenue swaps, LPI swaps, caps/floors, and options.
• Knowledge of real‑money inflation markets (linkers, breakevens) in addition to derivatives.
• Professional experience with inflation volatility modelling, smile/skew modelling, calibration frameworks, or hybrid rates/inflation models.
• Professional experience with a compiled language (Rust or C++) for performance‑critical analytics.
• Familiarity with production quant libraries and large‑scale analytics platforms.
