  • Experience with asynchronous programming, dependency injection, and unit testing frameworks.
  • Experience with Git, CI/CD pipelines, and Agile development methodologies.
  • Strong understanding of backend architecture, service integration, and scalable application design.
  • Strong analytical, troubleshooting, and problem-solving skills.
  • Excellent communication and collaboration skills.

Nice to have:

  • Experience with Microsoft Azure or AWS cloud services.
  • Familiarity with microservices architecture and containerization technologies such as Docker or Kubernetes.
  • Experience with message queues, caching mechanisms, or distributed systems.

Job Duties:

  • Design, develop, and maintain RESTful APIs and backend services using C# and .NET Core.

  • Define and maintain API specifications to ensure consistency, discoverability, and integration across applications.
  • Develop and optimize data access layers using Entity Framework Core and SQL Server.
  • Collaborate with Product, Front-End, QA, and Engineering teams to translate business requirements into reliable technical solutions.
  • Apply software engineering best practices, including clean code, design patterns, automated testing, and version control.
  • Contribute to CI/CD processes and continuous improvement of development workflows.
  • Troubleshoot and resolve complex application performance, scalability, and integration issues.
  • Conduct code reviews and provide technical guidance and mentorship to other developers.
  • Participate in architectural discussions involving backend services, API governance, and system integration.
  • Ensure applications meet quality, performance, security, and maintainability standards.

  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
