Quant Developer Credit

A leading global investment bank in the City of London is looking to hire a Quant Developer – Credit on a contract basis. This is an initial 6-month contract with the option to extend, paying a day rate in the region of £800 to £925 per day.

This role sits within a Quantitative Analytics function, initially aligned to a credit-focused programme supporting the development and improvement of risk models. The focus is on modernising existing models and improving how they are built, structured and maintained, rather than pure front office pricing.

The business is going through a broader modernisation programme and is looking for someone to play a key role in that transition. There is also scope to gain exposure to other asset classes and areas of the business over time, as well as the opportunity to move into a permanent role if of interest.

Key responsibilities

1. Redevelop and translate existing quantitative models into Python
2. Improve model structure, performance and maintainability
3. Work closely with quants and risk teams to understand model logic and outputs
4. Support testing, validation and deployment into production
5. Contribute to development best practices, including version control and testing

Experience required

1. Strong Python development experience within a quant or risk environment
2. Experience working with credit risk, fixed income or similar asset classes
3. Good understanding of econometrics or time series modelling
4. Experience working within financial services, ideally banking
5. Comfortable working across the full development lifecycle

Beneficial

1. Experience working with or translating R code
2. Exposure to C++ or working within mixed technology environments
3. Front office or desk facing exposure working with quants or traders
4. Knowledge of derivatives, XVA or broader risk modelling
5. Experience working with modern data platforms or cloud environments

This is a strong opportunity to join a well-established team working on a high-priority programme within a global bank, with scope to broaden your exposure beyond credit over time.

If you are a Quant Developer with the above experience, please respond with an up-to-date CV.
