At Nationwide we offer hybrid working wherever possible.

Day to day that means a mix of development work (developing RESTful APIs and microservices complex SQL queries depending on what the problem needs), execute production deployments, proactive monitoring and incident response, and working directly with our Fraud or Financial Crime business teams to understand what we need to build next. You’ll coordinate with our platform vendors to improve operational processes and improving observability., Our customer first behaviours put customers and members at the heart of how we work together.

• 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.
