What we do

We use Data Science techniques to support colleagues in delivering value for Nationwide and our members, identifying opportunities to generate income, reduce costs and maintain legendary service.

Our employee benefits

Competitive salary

And a range of special offers to reward employees who pay their salary into a Nationwide current account

Generous holiday allowance

24 days, increasing to 30 days per year. We also give our employees the option to ‘buy’ up to an extra 10 days holiday.

Flexible working

This can include options such as flexi-time, part-time, job sharing and term-time working.


Using Big Data

The world is a noisy place with constant interactions producing mountains of structured and unstructured data, aptly called Big Data. Data Scientists use their expertise and cutting-edge technology to draw actionable insights from this Big Data and Nationwide has put in place an infrastructure to support them. Senior Business Intelligence Manager Graeme Reed explains.

Rewarding our members

Data scientists commonly find that insights are not used in decision-making, but at Nationwide we are enriching our data enabled capability, with Data Science supporting core business decisions. Investing in listening to our members and analysing how they prefer to do business with us means we can make developments that save them time and money, which is key to what we do as a Society and rewarding for us. 

Rising to the challenge

Challenges for Data Scientists can be around the data itself, including how 'dirty' it is, its availability as well as privacy issues. Our Data & Analytics Community has expanded its Data Quality capability to ensure that issues are addressed at an early stage of the data life cycle.

We all need the right tools for the job too, and we have a slice of the £4 billion investment in tech announced recently. We're ensuring tooling for key technical activities is robust and up-to-date, with for example Hive Hadoop and Python3 being rolled out across the business.

Nationwide has a clear Data Strategy that recognises the importance of Data Science and has a clear direction to go in with the available data.

We'll continue to put insight from data at the forefront of business decisions. If you want to join us, check out our vacancies or get in touch via the start a conversation form above.
