Data Tester

We are establishing a new Finance UAT & Enablement team to support the delivery of large, complex Finance change initiatives, including the integration of Virgin Money and major transformation programmes. 

This role is hands‑on and delivery focused, with opportunities to shape test coverage and contribute to improving how we approach testing. 

This role is ideal for a tester who enjoys working closely with business users, handling data‑rich testing, and delivering high‑quality evidence in a regulated environment. 

We are happy to consider flexible working approaches to help you perform at your best.
 

The working hours (per week) for this role can be between 30 and 35 hours.

At Nationwide we offer hybrid working wherever possible. More rewarding relationships are supported through our hybrid approach, bringing colleagues together across our UK wide estate, whilst also supporting generous access to home working. We value our time in the office to solve problems, to learn, and to feel connected.

For this job you'll spend at least two days per week, or if part time you'll spend 40% of your working time, based at either our Swindon, London, Northampton, Bournemouth or Glasgow office. If you’re based at our Glasgow office, this will apply from 1 April 2027 and ahead of that there will be a need to regularly connect with colleagues for collaboration events. If your application is successful, your hiring manager will provide further details on how this works. You can also find out more about our approach to hybrid working here. 

If we receive a high volume of relevant applications, we may close the advert earlier than the advertised date, so please apply as soon as you can.

What you’ll be doing

Working with SMEs and delivery teams, you’ll build a clear understanding of business processes and testing requirements. You’ll also scope and design test cases aligned to requirements, user stories and acceptance criteria, and carry out functional and regression testing across change activity. 

Additionally, you’ll support User Acceptance Testing (UAT), helping ensure solutions meet business needs. As issues arise, you’ll identify, log and track defects, working closely with teams to resolve them. You’ll also provide clear, timely updates on testing progress, contributing to an accurate view of overall delivery status.

Our customer first behaviours put customers and members at the heart of how we work together. They are the set of behaviours that every colleague needs to display, in every role:

• Say it straight - We are brave in speaking out and saying what we think – we’re honest and direct with good intent, openly sharing diverse perspectives to reach the best conclusions and using language everyone can understand

• Push for better - We don’t settle for mediocrity, we challenge the status quo, taking responsibility for continuous improvement and personal development

• Get it done - We prioritise what will have the greatest impact, we are decisive, and we take accountability for delivering brilliant customer outcomes

You can strengthen your application by showing how our customer first behaviours resonate with you, and where you may have already demonstrated these.

We forge our own path at Nationwide.
