Simple loans. Smart investments.


At Zopa, we’re shaping the future of finance.

We offer simple loans and smart investments that help people take control of their finances and do more with their money. In the 12 years we’ve been in business, we’ve helped more than 60,000 people lend over £3 billion to 246,000 UK consumers.

And our journey’s only just beginning. In November 2016 we announced our plans to build a next generation bank so that we can bring a greater range of smart, ethical finance products to even more people.

The role
Data scientists at Zopa work on a broad range of topics such as risk modelling, pricing, marketing and operational research. The daily job of a data scientist includes extracting actionable insights from data with statistical analysis, identifying problems and opportunities in the business, proposing new ideas and experiments, developing and deploying machine-learning models and optimization algorithms in production.
 
Data scientists at Zopa work primarily as part of cross-functional teams known as Tribes, which are autonomous groups with ownership of one of our products, such as personal loans, P2P investments, credit cards, etc. Data scientists interact daily with analysts, product managers and software engineers in their own Tribes.
 
Data scientists also have close interactions with each other through the functional group known as the Data Excellence Chapter, where we share knowledge and experience on data science technologies and research. You may also help build our AWS analytical infrastructure with data engineers, mentor data analysts, and contribute to our efforts on Data Democratization
