  • Deep understanding of microservices architecture, asynchronous messaging systems, and web communication (REST, OpenAPI/Swagger, and API-First approach).

  • Everyday proficiency with Git and Maven.

  • Sound knowledge of backend security practices and a commitment to writing clean, high-coverage unit and integration tests.

  • Fluency in English (both written and spoken).

Nice to Have

  • Hands-on experience with cloud-native and infrastructure tools like Kubernetes, Ansible, or OpenSearch.

  • Familiarity with build and deployment automation (CI/CD via Jenkins, SonarQube).

  • Experience implementing automated testing frameworks.

  • Past involvement in high-level technical architecture and design.
