Job Description

The Quantitative Analytics team within the investment banking division is seeking a skilled and motivated Credit Quant Developer to support a high‑priority migration of risk model code. This role focuses on quantitative risk (Market, Credit and Interest Rate Risk) rather than front‑office pricing, and plays a vital part in enhancing the stability and adaptability of the firm's credit banking book models.

You will be responsible for translating and restructuring existing model components, primarily migrating code from R to Python - ensuring the newly implemented versions are efficient, well‑organised and maintainable. This role requires strong technical ability, excellent problem solving skills and a solid foundation in econometrics and time‑series methodologies.

Key Responsibilities:

• Lead the migration and translation of quantitative model code, focusing heavily on transitioning existing R models into Python.
• Develop and implement clean, logical and scalable code structures that can be easily adapted to evolving business and regulatory needs.
• Apply strong econometric knowledge to handle model challenges, identifying improved coding solutions when direct translation is not suitable.
• Work collaboratively within the Credit QA team to produce well‑documented, thoroughly tested and production‑ready model code.

Ideal Qualifications

• Strong programming ability in Python, including experience using GIT or similar version‑control tools.
• Solid understanding of econometrics, including foundational concepts such as linear regression, time‑series analysis and factor analysis.
• Experience working within the banking or broader financial services sector, ideally within a regulated environment
• A critical, analytical mindset with the ability to review and challenge model behaviour and code quality.

Nice to have

• Familiarity with R / R‑Studio or the ability to comfortably interpret R code, which supports the migration process.
• Understanding of C++ for potential cross‑team collaboration.
• Exposure to quantitative risk domains including Market Risk, Credit Risk or Interest Rate Risk.
• Advanced econometric knowledge, such as experience with capital models, meta‑models or correlation modelling.
