Senior .NET Engineer

We are searching for a Senior .NET Engineer to become part of the migration team, contributing to the breakdown of a .NET Framework 4.8 / VB.NET desktop application into ASP.NET Core (Current) backend services running on Kubernetes. The engagement kicks off with the project's highest-risk element — profiling and replacing a 14,518-line VB.NET data layer with EF Core repositories against a multi-tenant PostgreSQL schema secured by Row-Level Security — and then extends across backend services depending on team allocation. All services follow the same consistent patterns throughout: ASP.NET Core, EF Core, PostgreSQL, JWT tenant middleware, Docker, Kubernetes manifests.
