You should have deep expertise in both source and target platforms, strong scripting skills (Python or shell), and a solid understanding of large-scale source control and CI/CD systems. You will be responsible for planning, executing, and validating migrations, ensuring minimal disruption to development workflows, and optimizing post-migration processes. Relevant Experience: 3 to 4 years of specific experience working with GitHub Enterprise and Azure DevOps (ADO), with hands-on migration of ADO pipelines to GitHub Actions. Experience with migration from other SCMs (Perforce, Bitbucket, SVN, etc.) to GitHub is required. Responsibilities: Analyze and prepare repositories in ADO, Perforce, Bitbucket, SVN, and other SCMs, including workspace cleanup, stream merging, and file optimization. Lead the migration of source code and CI/CD pipelines from various SCMs to GitHub and GitHub Actions, including workflow translation, secrets management, and integration with third-party tools. Configure and optimize GitHub Actions workflows to replicate or enhance existing pipeline functionality from source SCMs. Handle large files efficiently by configuring Git Large File Storage (LFS) to accommodate files exceeding GitHub's size limits. Use migration tools (e.g., git-p4, custom scripts) to move repositories and pipelines, ensuring data integrity and workflow continuity. Plan migration scope, including history retention, repository structure, and pipeline mapping. Manage branch renaming, repository organization, and workflow optimization post-migration. Collaborate with development and DevOps teams to determine migration points, validate workflows, and confirm shared migration strategies. Troubleshoot issues related to file sizes, workflow compatibility, permissions, and network during migration. Validate CI/CD pipeline functionality post-migration to ensure seamless build, test, and deployment processes. Document migration processes, best practices, and provide knowledge transfer to internal teams. Required Qualifications: Strong knowledge of Git/GitHub version control systems and Azure DevOps (ADO), including pipeline and workflow management. Demonstrated experience migrating source code and pipelines from ADO, Perforce, Bitbucket, SVN, or similar SCM tools to GitHub and GitHub Actions. Experience with YAML workflow translation and secrets management in GitHub Actions. Familiarity with cloud infrastructure (AWS, Azure) and containerization (Docker, Kubernetes). Proficiency with migration tools (e.g., git-p4) and custom scripting (Python, shell) for automation and workflow translation. Ability to analyze and restructure repositories and pipelines for optimal performance in GitHub. Experience planning and executing source control and CI/CD migrations, including branch mapping, permission translation, and workflow validation. Familiarity with CI/CD pipeline integration and validation post-migration to ensure uninterrupted testing and deployment. Understanding of source code management best practices, version history handling, and repository organization in GitHub. Excellent communication and collaboration skills to work with cross-functional teams and address technical challenges. Practical migration experience, source control expertise, and the ability to manage repository history, large file storage, and CI/CD pipeline configurations for a smooth transition from other SCM tools to GitHub and GitHub Actions.
