Senior Developer in Newcastle upon Tyne

Join our day-to-day Banking team as a Senior Developer, helping to deliver change and maintain the Fujitsu Mainframe savings platform. You’ll play a key role in supporting account migration to a new platform, enabling safe decommissioning of the current system, and protecting reliable service for colleagues and customers.

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 21 and 35 hours. This is a 6-month secondment opportunity. 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 role, you'll be based at your nearest regional office or hub. We value time spent together to connect with colleagues for collaboration so there will be a regular requirement to attend our Gosforth site approximately once per quarter. If you are based at an office location, you'll be expected to meet our hybrid working requirement of at least two days a week, or 40% of your working time if part-time, in the office.

If your application is successful, your hiring manager will provide further details on how this works. Virgin Money is now part of Nationwide. Nationwide acquired Virgin Money in October 2024. Virgin Money continues to serve customers on the high street, and there will be a phased and considered integration over the coming years. You’ll be employed by Nationwide from day one, delivering real impact and benefitting from a highly competitive range of benefits. We’re a workplace where you’re rewarded, recognised and celebrated. Nationwide is committed to the redeployment of our employees impacted by change, as such applications for redeployment candidates will be prioritised in this recruitment process.

Responsibilities

In this role, you’ll design, build, test and support Fujitsu Mainframe solutions that help deliver business change safely and effectively. You’ll work in a small specialist team, planning and tracking work through Jira while balancing multiple priorities. Day to day, you may be developing new changes, reviewing code, sharing knowledge with colleagues, resolving defects, or supporting live service incidents. The role also includes participation in an on-call rota to help protect out of hours processing and keep critical services available for colleagues and customers.

About you

As a minimum requirement, you’ll have:

• Fujitsu Mainframe development experience across the full change lifecycle, from analysis and design through to build, test and implementation
• Experience supporting business-critical core banking applications in a complex technology environment
• A practical problem-solving approach, with the ability to stay calm, focused and effective during live service incidents
• The ability to manage your own workload across multiple concurrent tasks, priorities and delivery timelines
• A collaborative working style, including experience of peer review, knowledge sharing and constructive feedback
• A focus on quality, standards and safe delivery when making changes to critical systems

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.
