Description :

We are seeking a software engineer to help modernize and maintain our core applications across the Microsoft stack. The role involves working with C# in both .NET Framework 4.8 and .NET 8, supporting migrations from legacy ASP.NET MVC / Web API patterns to modern solutions using EF Core and SQL Server. You’ll also contribute to front-end development as we transition from AngularJS to Angular, integrating with secure .NET Web API backends.

Experience with performance tuning, DevOps practices, and secure configurations will be valuable in ensuring reliable, scalable systems.

  • Entity Framework 6 and EF Core (migrations, performance tuning, parameterized LINQ, interceptors)
  • SQL Server 2019-2022 (T-SQL, indexing, query plans, performance troubleshooting)

Frontend

  • AngularJS to Angular (v20) experience, solid TypeScript, but from an integrated MS Stack perspective
  • Familiarity with integrating Angular frontends into an .Net 4.8 / 8 Web API backend leveraging MSAL

    • Windows / IIS & services

  • Understands the impacts of IIS hosting, ARR / load balancing, Windows Authentication / Entra ID transitions
  • Understands the impacts of Windows Services, Windows Scheduled Tasks, and Hangfire for background jobs
