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.
