Description du poste

A public-sector social-security organisation is maintaining and extending applications that support statutory services for self-employed workers. The fullstack .NET developer role covers frontend and backend delivery with C#, .NET Framework, .NET Core and Blazor, alongside Azure Cloud automation through Azure DevOps CI/CD pipelines.

The mission

More than 150 people work in the IT department, which is organised into ten multidisciplinary development teams. Each team has around ten members, including developers, business analysts, test analysts, an Ops Engineer, a Product Owner and a Scrum Master. Teams use Agile/Scrum delivery within a SAFe environment and maintain applications that support core administrative processes. The landscape includes C#, .NET Framework, .NET Core, Blazor, MS SQL and Azure Cloud, with service communication through gRPC Remote Procedure Calls and NServiceBus messaging, as well as WCF.

Working in this role, you will design, develop and maintain .NET applications across frontend and backend layers. You will translate functional analyses into technical designs, support business analysts in validating specifications, and ensure that new functionality meets expected quality and performance levels. Delivery takes place iteratively with developers, testers, business analysts, the Product Owner, Scrum Master and Ops Engineer. You will also resolve second-level technical issues, contribute to documentation and share implementation knowledge with junior developers.

Your responsibilities

• Design and deliver frontend and backend functionality with C#, .NET Framework, .NET Core and Blazor, keeping implementations aligned with validated technical specifications.
• Build Azure DevOps CI/CD pipelines for .NET applications and maintain unit tests that keep development, test and production environments stable.
• Integrate application components through gRPC Remote Procedure Calls, WCF, NServiceBus or another suitable messaging pattern.

• Improve development processes, software quality and application performance by evaluating relevant technologies and methods.
• Produce and review technical documentation, and share knowledge across the multidisciplinary team.
