Summary Generated by Built In

 

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.

 

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.

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

 

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.

 

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.

Responsibilities

 

What you’ll be doing

 

As an E3 Engineer within the Conversational Banking value stream, you will work across our conversational platforms, contributing to both the modern AWS Connect-based stack and the existing legacy solutions that remain critical to our day-to-day operations.

 

Designing, building, deploying and operating features and services that support Voice, Video and Chat interactions on AWS Connect whilst contributing to the ongoing transition from legacy technologies to a more unified, cloud-native platform whilst ensuring stability and continuity.
 

About you

 

As a minimum you’ll have:

 

  • Development experience ideally in Python and/or Node.js
  • Experience with AWS including AWS Connect, Lambda, S3 and DynamoDB
  • REST API design and integration experience aligning to industry standards
  • Experience working in agile, DevOps-driven teams
  • Experience leading code reviews, design discussions and knowledge sharing
  • Problem-solving and root cause analysis skills, with industry best practices

 

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:

 

  • Feel what customers feel - We step into our customers’ shoes, using their feedback and insights to empathise with them and to understand their needs, so that every decision we make starts and finishes with our customers in mind

  • 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.

Qualifications

 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.
