Software Engineer (C#)

What You Will Do Daily :

• Develop next-gen features for Visual Studio : You will actively contribute to feature specifications and write high-quality C# code to bring them to life. You will dive deep into the Visual Studio Extensibility SDK , becoming the squad’s specialist in the Microsoft ecosystem to deliver software that feels snappy and native.
• Bridge the gap to our Core Engine : While your primary focus is C#, you will interact with our shared analysis engine (SLCore, written in Java). You will ensure the Visual Studio extension consumes this shared logic efficiently, collaborating with the team to expose new capabilities.
• Solve real engineering constraints : You will learn to build for "Zero Friction." You will write code that respects the user's memory and CPU, ensuring we never block the UI thread or slow down the developer's "inner loop."
• Implement the "AI Verification" UX. You will build the user interfaces (diff views, issue highlights, fixes) that guide developers when checking AI-generated code, helping turn "generated code" into "shippable code."
• Grow your craft in the Open Source world . You will review code from peers, engage with community feedback, and see your contributions used by millions of developers.
