Sr C# Developer/Support

This is a remote position.

About the role

This is a versatile senior C# pod, not four slots on one project. These developers rotate across multiple Client workstreams, leaning into migration/conversion support when that work surges and picking up other C# projects otherwise. The role rewards people who ramp fast, context-switch cleanly, and are comfortable across different codebases and problem types. Frame it as flexible senior muscle, not bench or generic staff augmentation.

What you will do

• Move across multiple Client C# workstreams as priorities shift.
• Support the Java-to-C# migration effort during peak periods: reviewing and finishing AI-converted code, building out C# services, proving parity.
• Pick up feature development, defect work, and enhancements on other C# projects between migration surges.
• Ramp quickly on unfamiliar codebases and deliver with minimal hand-holding.

Must have

• Strong C# / .NET:8+ years, .NET Core / .NET 6+, ASP.NET Core, dependency injection, async/await.
• Adaptability:demonstrated history of working across multiple projects, clients, or codebases; comfortable ramping fast and switching context. This is a stated requirement, not a footnote.
• Data and API fundamentals:SQL, EF Core or Dapper, REST APIs.
• Self-direction:delivers independently across changing assignments.

Nice to have (strong pluses)

• Code migration or application modernization experience (including framework upgrades such as .NET version migrations). Directly relevant to migration overflow.
• Java familiarity, enough to help on conversion work when needed. Valued, not gated.

•AI coding tool experience.

• Cloud (Azure or AWS), containerization, CI/CD.
