• Strong understanding of Maven, Gradle, dependency management, and artifact lifecycle management. 

• Experience with Artifactory or similar enterprise artifact repositories. 

• Knowledge of CI/CD pipelines, automated testing, code quality controls, and release management. 

• Experience with GitHub, source control management, branching strategies, and pull request processes. 

• Familiarity with legacy modernization, mainframe-to-Java migration, code conversion, or re-platforming initiatives. 

• Working knowledge of relational databases and SQL; DB2 LUW experience preferred. 

• Strong debugging and root-cause analysis skills.

Artifact Repository Management 

• Build, package, version, and publish approved Java artifacts to Artifactory. 

• Manage artifact versioning, release governance, dependency tracking, and deprecation strategies. 

• Ensure shared artifacts are properly documented and available for enterprise consumption. 

Development & Support 

• Review, maintain, and enhance converted Java utilities, common-code components, and shared services delivered through Mainframe modernization. 

• Analyze code for maintainability, performance, reliability, operational supportability, and security. 

• Support defect triage, root-cause analysis, remediation planning, and validation activities involving shared platform components. 

Consumer Team Enablement 

• Partner with application teams consuming shared libraries and common services. 

• Provide guidance on library adoption, upgrade planning, dependency management, and integration best practices. 

• Support onboarding of new application teams to common components. 

Build, Release & Quality Engineering 

• Maintain build pipelines and automated validation processes for shared components. 

• Implement and support automated testing, code quality analysis, and security scanning. 

• Ensure artifacts meet enterprise quality, security, and compliance standards before publication.
