• Participate in architecture reviews, design sessions, and backlog refinement.
• Conduct code reviews and refactor existing backend components for scalability, maintainability, and security.
• Integrate backend services into CI/CD pipelines with automated builds, tests, and scans.
• Ensure secure coding practices and interpret output from static and dynamic security analysis tools.
• Use scripting languages, including Python and Bash, to automate operational and deployment tasks.
• Troubleshoot complex backend issues across application logic, integrations, data stores, and cloud resources.
• Mentor team members in API design, backend architecture, and secure coding patterns.

• Minimum Experience: 3+ years of professional development, including at least 3 years of Java development.
