Full-Stack Developer (Blazor / .NET) - Immediate Start Only

Overview

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.

• Participate in Agile ceremonies, help refine user stories, and challenge assumptions to ensure technically sound and valuable feature delivery
• Work from design prototypes in Figma, implementing responsive, accessible, and pixel-perfect UI components using Razor, Blazor bindings, and modern CSS frameworks (e.g., TailwindCSS or Bootstrap)
• Ensure strong application security through secure storage, encrypted communications, and identity protocols aligned with best practices
• Build and maintain automated testing suites using xUnit, bUnit, Playwright, or similar frameworks to ensure high-quality releases
• Manage CI / CD workflows and infrastructure provisioning via Azure DevOps, including pipelines, artifacts, configuration management, and release automation
• Monitor application performance and reliability post-deployment using Application Insights, Log Analytics, or similar telemetry solutions
• Drive continuous improvement across the engineering lifecycle, contributing to the evolution of internal frameworks, coding standards, and dev tooling
