Senior Full Stack Developer (Blazor & .NET are MUST have)- Perm role

JOB SUMMARY:

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.

KEY RESPONSIBILITIES

• Collaborate closely with product teams to translate business challenges into scalable and maintainable software solutions

• Lead the development of web applications using Blazor (WebAssembly and Server), delivering dynamic, componentbased UI’s integrated with secure, high-performing API’s

• Design and maintain API layers using .NET Core, incorporating authentication (OAuth2, JWT), request validation, and rate limiting where applicable

• Architect robust, modular C# backend services, applying domain-driven design and deploying within containerized environments (Kubernetes experience is a plus)

• Build and maintain relational data models using Microsoft SQL Server, optimizing performance through indexing, partitioning, stored procedures, and other database tuning techniques

• Collaborate with data engineering teams to support ETL pipelines, operational data marts, and analytics-ready schemas within a structured medallion architecture

• Integrate Large Language Models (LLM’s) such as OpenAI into products using secure API calls, embedding techniques, and prompt engineering best practices

• 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

• Stay up to date with the latest advancements in the .NET ecosystem, Azure services, and Blazor framework, and proactively share knowledge with the wider team

REQUIREMENTS

• Fluent in English and Arabic

• Excellent communication and collaboration skills in cross-functional, agile environments

• Strong analytical mindset and attention to detail across quality, security, and performance
