Strong experience writing unit, integration, and performance tests (JUnit, Mockito, etc.).
Practical experience with CI/CD pipelines and deployment automation.
Strong knowledge of Docker and container-based development environments.
Ability to mentor other engineers and elevate the technical quality of the team.
Strong communication and decision-making skills.
(Optional) Exposure to additional backend languages (Node.js, Python, Go).
