Data Scientist

Data Excellence – Data Science
Full Time
Hello there. We’re Zopa the Feel Good MoneyTM company.
In 2005 we built the first ever peer-to-peer lending company to give people access to simpler, better-value loans and investments. Since then we’ve helped hundreds of thousands of customers take the stress out of money by building our business on honesty, transparency and trust.

It works so well that we want to give our customers access to other great products and tools, empowering them to better manage their money. That’s why, in December 2018, we launched a different type of bank, allowing us to bring a greater range of smart 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
