We are looking for a seasoned Senior .NET Developer to join our core engineering team. In this role, you will serve as a technical anchor, bridging the gap between our established enterprise systems and our next-generation applications.
You are the ideal candidate if you are just as comfortable debugging a complex MVC 5 application as you are architecting microservices in .NET 8. You understand that "modernization" isn't just a buzzword—it's a careful process of refactoring, migrating, and improving existing codebases without disrupting business operations.
Key Responsibilities
Develop & Maintain: Support and enhance existing legacy applications built on .NET Framework 4.8 (MVC) while ensuring stability and performance.
Modernize & Migrate: Lead initiatives to port modules and functionalities from legacy frameworks to .NET 8+, utilizing EF Core.
Database Optimization: Write, analyze, and optimize complex T-SQL scripts, stored procedures, and triggers. You will be responsible for tuning performance in high-transaction environments.
Full-Stack Implementation: Build responsive and user-friendly interfaces using Bootstrap 5, utilizing jQuery for DOM manipulation in legacy views and modern vanilla JS/Blazor for new components.
Architecture & Mentorship: Guide junior developers on best practices for both ORMs (EF6 and EF Core) and conduct code reviews to ensure clean, maintainable architecture.
Backend Core:
Deep expertise in C# and .NET Framework 4.8 (ASP.NET MVC).
Strong proficiency in .NET 8+ (Core) for new API and service development.
Data Access (ORM):
Extensive experience with Entity Framework 6 (edmx, database-first, or code-first workflows).
Proven experience implementing EF Core 8+ in a modern dependency-injection environment.
Database:
Advanced T-SQL scripting skills (stored procedures, views, indexing, execution plans) on Microsoft SQL Server.
Frontend:
Solid grasp of jQuery for maintaining and extending existing client-side logic.
Proficiency in Bootstrap 5 for building responsive, mobile-first layouts.
Experience with Azure or AWS cloud services (App Services, SQL Azure).
Knowledge of modern JavaScript frameworks (Vue.js, React, or Angular) to assist in future frontend migrations.
Experience with CI/CD pipelines (Azure DevOps, GitHub Actions).
Understanding of Dependency Injection (DI) patterns in both legacy and modern .NET.
Pragmatism: The ability to choose the right tool for the job (knowing when to refactor vs. when to rewrite).
Communication: Ability to explain technical debt and modernization strategies to non-technical stakeholders.
