Responsibilities
- Modernization & Development:** Design and build scalable, high-performance applications using **.NET 10, Blazor**, and **C#**.
- Legacy Maintenance & Migration:** Maintain, optimize, and refactor existing enterprise applications running on .NET Framework 4.8.
- You will be key in strategizing how to move these features forward using patterns like the Strangler Fig.
- Database Architecture:** Design and manage complex data structures in **Microsoft SQL Server**.
- You must be comfortable writing and tuning raw T-SQL and stored procedures---we deal with heavy data where ORMs aren't always enough.
- Complex Problem Solving:** Troubleshoot issues that span across generations of code.
- We need someone who can trace a bug from a modern API back to a legacy backend and fix the root cause.
- Mentorship:** Act as a technical anchor.
- Help the team adopt modern .NET features while respecting established business logic.

Education
- (Not required) – Modernization & Development:** Design and build scalable, high-performance applications using **.NET 10, Blazor**, and **C#**.
**The Mission**
We are looking for a **Senior .NET Developer** who can handle the complexity of a dual-stack environment. We operate with **.NET Framework 4.8** for our core legacy systems while actively developing new solutions in **.NET 10**.
We need a developer who can "get into the thick of it." You won't just be writing new features; you will be analyzing legacy logic, refactoring architectural debt, and building the bridge to the future. If you are comfortable digging into a complex 4.8 monolith one day and architecting in Modern .NET the next, this is the role for you.
