As a Senior .NET Developer, you'll work closely with end users, Product Owners, and Business Analysts to turn real business needs into automated solutions that cut costs and boost productivity. You'll build across the full stack - from React front ends to Azure-based backend services - and take ownership of both new development and the modernization of legacy .NET applications. You'll collaborate daily with QA Engineers, Architects, and business stakeholders, and your voice will carry weight in architecture and technical design discussions. Success in this role looks like shipping reliable, well-architected software with urgency, while helping the team around you get better along the way.
Key Responsibilities

• Design, develop, and maintain enterprise applications using C# and modern .NET, delivering cloud-native solutions on Azure.
• Build modern, responsive web applications with React, React Router, and ASP.NET Core, with a strong focus on UI/UX.
• Develop and publish RESTful APIs through Azure API Management, and build scalable serverless solutions with Azure Functions.
• Architect event-driven integrations using Azure Service Bus and Azure Storage, and implement distributed caching with Azure Cache for Redis.
• Optimize Azure SQL Database and SQL Server performance, including stored procedures, functions, and complex queries powering high-performance applications.
• Lead the modernization of legacy .NET applications into cloud-native architectures, partnering with Product Owners, Business Analysts, QA Engineers, and Architects throughout the SDLC.
• Drive code quality and team growth through code reviews, mentorship of junior developers, and adoption of AI-assisted development tools like GitHub Copilot.

Required:

• 7+ years of professional software development experience with C# and .NET, including .NET 8+ (or modern .NET), ASP.NET Core, and Entity Framework Core
• Strong experience with SQL Server and Azure SQL Database, and designing, building, and consuming RESTful APIs
• Strong front-end experience with React, React Router (v7 or modern routing frameworks), TypeScript, HTML5, CSS3, and responsive design
• Hands-on experience building cloud-native applications in Microsoft Azure, including App Services, Functions, API Management, Service Bus, Storage Accounts, Cache for Redis, Key Vault, and Application Insights/Monitor
• Experience securing APIs and applications using Microsoft Entra ID, OAuth 2.0, and OpenID Connect
• Strong understanding of object-oriented design, software architecture, and design patterns, with experience writing unit tests, using Git, and troubleshooting production systems within CI/CD pipelines
• Bachelor's degree in Computer Science, Information Technology, Engineering, or a related field, or equivalent professional experience

Preferred:

• Experience with legacy Microsoft technologies (ASP.NET Web Forms, ASP.NET MVC 5, jQuery, CSS2) or modernizing legacy .NET Framework applications
• React Router v7 Server-Side Rendering (SSR), TurboRepo/Monorepo architecture, Tailwind CSS, or component libraries like Base UI
• Azure AI Services or experience building AI-powered applications
• GitHub Actions, Azure DevOps, Docker, or Infrastructure as Code (Bicep, ARM Templates, or Terraform)
