Job description
This is a remote position.
About the role
IL6 is C#-heavy. This is a C#-first role: the must-have is strong C# / .NET, and Java is a genuine plus that breaks ties, not a gate. Do not reject strong C# candidates for weak Java on this one. The developer will build and evolve C# services as part of Client's data migration and API work, including the data access layer and API surface pointed at the consolidated MySQL database.
What you will do
Build and maintain C# / .NET services in the IL6 codebase.
Contribute to the rebuilt data access layer and the new API design as 30 databases consolidate into one MySQL instance.
Design and implement REST APIs to stable contracts, including versioning and consumer segmentation (app, integration, reporting).
Tune data access for performance (EF Core or Dapper, query design, indexing, caching).
Write automated tests and support CI/CD.
Must have
Strong C# / .NET:8+ years, deep with .NET Core / .NET 6+, ASP.NET Core Web APIs, dependency injection, async/await.
Data access depth:EF Core and/or Dapper, connection management, query performance, SQL (MySQL or SQL Server).
API design:REST contract design, versioning, pagination, error handling.
Microservices and CI/CD:service-to-service communication, containerization, pipelines.
Communication:works independently, gives direct feedback, translates for stakeholders.
Nice to have (tie-breakers)
Java exposure, enough to read and reason about Java services during the migration. Valued, not required.
•Migration or modernization experience.
AI coding tool experience; interest in AI-assisted development.
•Kong, Azure or AWS, GraphQL.
