Data Scientist (Credit Risk)

The role of Data Scientist (Credit Risk) is important to us. They will be responsible for designing, building, validating and maintaining the credit risk models that will sit at the heart of how Radius makes credit decisions. The role will also share responsibility for data modelling and engineering within the credit department.

We will be happy to welcome you to our office in Crewe, with working hours from Monday to Friday from 8.30 am to 5.30 pm.

Your daily responsibilities will be...

• Design, build and validate credit risk models – application scorecards, behavioural scorecards, recovery propensity and lifetime-value models: using modern techniques such as gradient boosting and survival analysis.
• Translate credit and commercial questions into clear modelling problems, and turn model outputs into decisions the business can act on.
• Validate model performance and design monitoring so models stay accurate as the portfolio changes (for example Gini / CAP tracking and population stability).
• Work hands-on with raw data from multiple source systems, shaping it into clean, model-ready datasets.
• Partner closely with the Head of Credit Insights, the wider analytics team, Finance and Commercial to make sure models drive real credit decisions.
• Document methodology clearly and explain technical work to non-technical audiences.

• At least 3 years in a data science or quantitative modelling role, with a track record of building and validating predictive models.
• Strong Python and SQL, with practical experience across classification, regression and ideally survival analysis.
• Confidence working with messy, real-world data drawn from multiple source systems.
• A clear communicator who can explain models, and their limitations, to a business audience.
• Genuine curiosity about the credit domain and a drive to build, not just analyse.

What to expect from us?

• A friendly culture that reflects our proposition to customers.
• A fast-growing organization that defines itself as agile and innovative.
• A drive for continuous improvement, which will give you the opportunity to support from day one.
• A commitment to building a work environment that values inclusivity, innovation, agility and grit.

And, of course, competitive pay, a potential bonus, and a good range of basic benefits including hybrid working, real autonomy and the chance to help build a new data science capability within Credit from the ground up.
