C# /.NET Developer

About The Role: Jobrapido is seeking a mid-level C# / .NET Developer to build, maintain, and improve backend API services for our platform. This is a backend-focused position with particular emphasis on identity, authentication, and authorization services. You will contribute to cross-service capabilities and help deliver secure, high-performance APIs that operate reliably in a demanding production environment. You will work with ASP.NET Core, Redis, and relational databases, partnering with engineers across the platform to implement features and maintain established service patterns. The role involves building APIs within an internal REST server framework, supporting public and private hosting, and following conventions for documentation, compression, CORS, and error handling. The successful candidate brings sound .NET fundamentals, practical distributed-systems experience, and a careful approach to security and service reliability.

Qualifications: You have 3–5 years of professional experience developing with C# and .NET, including ASP.NET Core, and can contribute independently while collaborating effectively with other engineers. You understand REST API design, HTTP semantics, and API versioning, and are comfortable with asynchronous programming, dependency injection, and common .NET service patterns. You have hands-on experience with Redis, including caching, key design, connection management, and basic publish/subscribe patterns. You can write SQL queries, understand indexing and query performance, and have worked with PostgreSQL or SQL Server. Familiarity with Git, CI/CD pipelines, and deploying services to production is expected. Experience with OAuth 2.0, JWTs, API keys, multi-factor authentication, and key rotation is valuable. Additional relevant strengths include Polly or similar resilience libraries, observability and performance logging, production debugging under load, and experience tuning services for throughput and latency.

Responsibilities: Design, implement, test, and maintain REST API endpoints using C# and ASP.NET Core on .NET 8 or later. Contribute to identity and access services by applying appropriate authentication and authorization practices, protecting credentials and keys, and following established security standards. Integrate Redis-backed capabilities for cached data snapshots, low-latency data access, session and user-state management, and publish/subscribe use cases. Use Stack Exchange. Redis and related libraries where appropriate, and design data access patterns that support reliable operation across services. Write and optimize SQL queries and stored procedures for PostgreSQL or SQL Server as needed. Document endpoints with Swagger/OpenAPI and follow platform conventions for hosting, CORS, compression, and standardized error handling. Improve performance through effective asynchronous patterns, connection pooling, and relevant thread-pool configuration. Participate in code reviews, investigate production issues, and deliver iterative improvements in partnership with the wider engineering team.

Benefits: Jobrapido offers the opportunity to contribute to meaningful platform services and develop your skills alongside experienced technology professionals. You will work on backend systems involving modern .NET technologies, distributed data access, and production-scale API challenges. Further details about compensation, benefits, and working arrangements can be discussed during the recruitment process.

Equal Opportunity: Jobrapido is an equal opportunity employer. We are committed to providing a respectful and inclusive workplace and consider applicants without discrimination on the basis of protected characteristics under applicable law. We welcome candidates with diverse experiences and perspectives to apply.
