Software Engineer (Full Stack)

As a Software Engineer, you will be at the forefront of designing, developing, and maintaining cutting-edge software solutions. This role is perfect for individuals who are passionate about technology, possess strong problem-solving skills, and have a keen eye for detail. You will collaborate with cross-functional teams to deliver innovative products that meet the needs of our clients and drive the success of our organisation. You will work within the Digital Innovation team, building features that enhance our digital products and services.

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 our London office. If your application is successful, your hiring manager will provide further details on how this works.

As a Full Stack Software Engineer in our Digital Innovation team, you’ll play a key role in building and evolving the digital services that power experiences for millions of Nationwide members. You’ll work across the full software development lifecycle—designing, developing, testing, and deploying scalable web applications and APIs. You’ll collaborate closely with designers, product owners, and fellow engineers to deliver high-quality, accessible, and secure digital experiences. You’ll contribute to both front-end and back-end development, using modern frameworks and cloud-native technologies. You’ll help shape and maintain CI/CD pipelines, write automated tests, and ensure code quality through peer reviews and continuous integration practices. You’ll also look for opportunities to improve performance, simplify architecture, and reduce technical debt, whilst mentoring junior engineers and contributing to a culture of continuous learning and innovation.

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.
