.Net Senior Engineer E2 in Swindon

We’re looking for a Senior .Net Engineer to join our Credit Risk engineering team. You’ll be part of a feature team delivering high-quality, cloud-native services that support credit decisioning across a range of products, whilst ensuring strong engineering standards and alignment with platform guardrails. You’ll be part of our Credit Risk engineering team, working on a strategic platform that enables responsible lending decisions across mortgages, credit cards, current accounts, loans, and emerging business banking capabilities.

In this role, you’ll combine hands-on development with leadership of the junior engineering team. You’ll be responsible for delivering well-designed, scalable and high-quality solutions aligned with enterprise architecture and engineering standards. You’ll play a key role in translating technical designs into working software, driving engineering best practices, and maintaining delivery momentum within your feature area.

You will work closely with other engineers, architects, and product teams, contributing to a collaborative environment that supports continuous improvement and reliable delivery. 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 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 Swindon, London or Bournemouth site approximately once a month. 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. 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. If you’re a colleague on long-term absence (for example, on parental leave) or a temporary worker, please use your personal email address to submit an application.

Responsibilities

A typical day involves supporting your feature team to design and build services that support the Credit Risk platform while also supporting the junior engineering team. You will turn solution designs into working software, making sure the code is well structured, reliable, and performs well. Throughout the day, you will review code, support team members with technical challenges, and ensure everyone follows agreed standards and ways of working. You will also work with data systems and make sure changes are delivered smoothly through the release process. Alongside this, you will stay in close contact with stakeholders to keep work on track and deliver features on time.

For this role you will need experience of:

• Hands-on experience building applications using .NET Core (APIs)
• Experience working with document-based/NoSQL databases (e.g., MongoDB or equivalent)
• Solid understanding of API design principles and microservices-based architectures
• Experience contributing to production-grade systems with a focus on quality and reliability
• Working knowledge of CI/CD pipelines (GitHub Actions, Jenkins, or similar) and their importance in delivery
• Experience supporting a feature team or workstream, ensuring alignment to standards and timelines and supporting junior engineers.
• Ability to enforce engineering guardrails and ensure consistent implementation across the team
• Experience demonstrating problem-solving skills and attention to detail in design and implementation
• Effective communicator with the ability to collaborate across engineering and product team
