A major public sector organisation is modernising internal applications and building new cloud-native services on Microsoft Azure. The work focuses on developing and maintaining ASP.NET Core Blazor frontends together with .NET backend services, supported by CI/CD pipelines and containerised deployment. This role combines hands-on .NET development with operational ownership of Azure services.
The mission
The modernisation programme is delivered by application teams aligned with a Cloud Center of Excellence, migrating legacy web apps to cloud-native architectures and introducing reusable modules and automation. You will work on managed, production-facing systems where efficiency, scalability and compliance are tracked through automated pipelines and monitoring.
As a junior Full Stack Developer you will translate requirements from analysts, project managers and architects into incremental delivery plans and working code. Typical activities include implementing new features in Blazor and ASP.NET Core, building REST APIs (including Minimal APIs), participating in code reviews, and helping to automate CI/CD and container deployments for Azure. You will also contribute to operational tuning and cost-aware optimisation of running services.
Your responsibilities
- Deliver production-ready features in ASP.NET Core Blazor and .NET backend services, ensuring code is testable and maintainable
- Implement and maintain REST APIs (ASP.NET Core, Minimal APIs) that integrate with SQL stores and caching layers
- Build and improve CI/CD pipelines to automate build, test and deployment to Azure and container platforms
- Monitor and optimise Azure services and containers for performance, availability and cost efficiency
- Enforce quality through code reviews, automated tests and team-level best practices defined by the Cloud Center of Excellence
- Troubleshoot and resolve technical incidents affecting the applications you own, including root cause analysis and corrective work
