Intern Data Science in Group Treasury

Group Treasury is at the core of the bank: we manage liquidity, steer interest rate risks and support strategic decision-making. Within this context, you will work on a machine learning project focusing on the analysis and prediction of customer behaviour in mortgage products (Baufinanzierung).

The objective is to better understand key behavioural drivers and improve our modelling approach in close collaboration with IT. This internship is designed for a duration of 3–6 months (preferred: 6 months).

Your tasks include:

• Support the development and improvement of a machine learning model for customer behaviour forecasting
• Analyse large datasets to identify relevant drivers and patterns in mortgage portfolios and key drivers of customer behaviour
• Work closely with Treasury and IT to translate analytical findings into model improvements
• Prepare results and visualizations for internal stakeholders

You will work on a hands-on project with real impact, where you are expected to take ownership and proactively drive topics forward.
