Data Scientist

Data Excellence – Data Science
Full Time
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 Science at Zopa is hands-on and quantitative. Our Data Scientists propose ideas, formulate them as hypotheses, test them with statistics, and present insights with actionable information across a broad range of topics, such as risk, marketing, fraud, pricing, and operations. Working within a multi-disciplinary team using the latest technologies in analytics and big data, a Data Scientist at Zopa will have the programming skills to go beyond what the tools can do.
For more clarity on our values and mode of operation, see our tech blog, and especially our posts on PredictorData Democratization, and the cross-functional tribal model we use.
