Job description

Your primary platform will be the Microsoft power platform and as such you will be supporting the development of both model driven and canvas-based applications which integrate with our on-premise system of records. However, we have several other solutions which your skills may be applicable to and as such you will be keen to learn and develop a broader set of skills ensuring that you can lead change in several areas.

The role will face challenges and require solutions involving third parties, cloud and some internally developed; creating a diverse opportunity to work within software development, integration and upgrades for a variety of solutions.

This role is within the colleague servicing value stream, who are responsible for building and maintaining solutions which support our retail colleagues. This role continues to develop our commitment to building key capabilities, enabling us to provide platforms and services which enable our colleagues and members to thrive.

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 offices. 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.

What you'll be doing

Your designs will ensure we continue to follow guardrails & best practice while maintaining a standard look and feel so that our solutions remain 'easy to adopt' by our business colleagues. Working with your team you will ensure this is delivered in the most efficient and pragmatic way.

About you

Your experience will be varied having been potentially gained from several roles, but will include the following:

• Strong experience developing on Microsoft technologies including Microsoft power (specifically power apps, power automate and dynamics 365). This will include building and developing teams to delivery specific goals.
• Development experience within a highly regulated environment with existing guardrails / standards. Ideally within a CoE (Centre of Excellence). Implementation of best practice and how such practices can be governed.
• Managed environments ideally with pipelines for delivery which have solid controls and gateways ensuring standards and quality are maintained.
• Experience of cloud to on premise integration including the configuration and use of on-premises gateways, ePaas, DLP Policies and (where appropriate) Firewall and DNS configuration. This will also include the building and integrating with SOAP, WCF, REST and microservices.
• Experience developing data stores (either relational (SQL) or NOSQL) and the use of the dataverse which support all Microsoft power solutions.
• Experience of azure related components (e.g. AzureAD, app registration & managed identities).
• Understanding complex problems, providing root cause analysis, and identifying options for resolution which you can communicate to both technical and non-technical colleagues.
• Strong leadership, stakeholder management & engagement skills

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.
