Job description

Nationwide is investing heavily in cloud, DevOps and agile ways of working to modernise our technology estate and improve how our teams build and operate services. Within Customer Servicing, the Conversational Banking value stream is central to this transformation, delivering the platforms used by our frontline colleagues to support members across a range of interaction channels.

Our focus spans Voice, Video and Chat interactions, which are being engineered, owned and evolved by the team as a single AWS Connect platform. This role sits at the heart of that journey by helping to transition from a complex legacy estate towards a more standardised, cloud-native stack, while continuing to operate and support existing services throughout the transition.

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

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 or London office. 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.

Banking – but fairer, more rewarding, and for the good of society

We forge our own path at Nationwide.

As a mutual, we’re owned by our members - those customers who bank, save or have a mortgage with us. We challenge the financial sector status quo. We don’t see customers as the engine of our own profit. We share our profits with them and put their needs first. Always there when they need us. Supporting them and their lives.

If you’re inspired by fairer finances, passionate about making a meaningful impact, and truly care about our customers, you’re one of us.

At Nationwide, you are challenged to grow and rewarded for doing so. Valued. Recognised. Inspired to be your best. As a community, we want our working lives to count. As a team, we celebrate what we achieve. As a standard-setter, we work for the good of customers, communities, and broader society.

We are purpose-driven. Uncompromisingly customer. Unstoppably Nationwide.

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