Full-Stack Developer (Blazor / .NET)

WHERE YOU FIT IN |

As a Full-Stack .NET Developer at Whiteshield, you will play a critical role in designing, building, and scaling high-performing web applications that underpin our digital platforms and flagship policy advisory products. You will be responsible for end-to-end development across the application stack, including Blazor front-end components, .NET Core back-end services, and Microsoft SQL Server data layers.

You will build modern, maintainable, and secure applications using the Blazor WebAssembly/Server framework, C#, and Entity Framework, while applying best practices in RESTful API design, domain-driven architecture, and database optimization. Your work will extend to developing cloud-native applications deployed on Azure  & on-premise deployments to IIS, incorporating CI/CD pipelines, infrastructure-as-code, and DevSecOps principles to ensure robust, scalable, and secure deployments.

This role demands a strong understanding of software architecture, data modelling, and emerging AI technologies, including opportunities to integrate LLM’s (e.g., OpenAI, Gemini) to enhance user experience and analytics. You’ll collaborate closely with cross-functional teams across design, technical, and business domains to deliver high-impact, production-grade software.
