We launched Chase UK to revolutionise mobile banking with seamless journeys that our customers love. We’re already trusted by millions in the US and we’re quickly catching up in the UK — but how we do things here is a little different. We’re building the bank of the future with a start-up mentality, meaning you’ll have the opportunity to make a real impact. As a Data Scientist within JPMorganChase’s International Consumer Bank, you’ll sit in our Business Analytics team and partner closely with Product, Marketing, Operations and Engineering. Your focus will be on using data, experimentation, and lightweight predictive modelling (e.g., churn/retention signals, propensity models). You’ll contribute to analytical direction, deliver high-quality analysis and experimentation, and translate outcomes into clear actions that improve customer experience and business performance. Our Business Analytics team is at the heart of this venture, focused on getting smart ideas into the hands of our customers. We’re looking for people who are curious, thrive in collaborative squads, and are passionate about practical problem-solving. We work in tribes and squads aligned to products and projects, and depending on your strengths and interests, you’ll have the opportunity to move between them. While we’re looking for strong professional skills, culture is just as important to us. We value diversity of thought, experience and background, and we want our teams to reflect the communities we serve.

Apply statistical methods to quantify impact and drivers (e.g., segmentation, cohorting ), and clearly communicate trade-offs and limitations. Build, validate, and maintain lightweight predictive models to support decisions (e.g., churn risk/retention targeting, response propensity, customer value proxies), prioritizing interpretability, stability, and measurable lift under guidance and with appropriate review. Follow and contribute to best practices for reproducible analysis and experimentation (documentation, code review norms, clear metric definitions).

Product and commercial curiosity: ability to balance rigor with speed and learn what is “good enough to decide” with guidance from senior partners.
