Lead Migration Engineer- US shift overlap

InOpTra Digital seeks a hands-on Lead Migration Engineer to lead the migration of a legacy Linux estate from a VMware data center to GCP. The role includes discovering and documenting system dependencies, planning and executing migration waves, coordinating cutovers and rollback, and leading an offshore engineering team.

Responsibilities:

• Lead hands-on discovery of the source estate with the client’s engineers: servers, applications, databases, scheduled jobs, network flows and every dependency on the shared file system. Document what is undocumented
• Group applications into logical units (application, minimum OS version, database integration, file dependencies) and plan the migration waves
• Plan and run the proof of concept and production pilot with the GCP Architect, and report go/no-go results to the client
• Prepare applications for the move. Work with the developers to containerize Perl applications where they fit, redeploy and test them on the existing servers, and move the rest as VMs
• Move MySQL databases as-is on VMs with their applications, with a tested backup, sync and rollback plan
• Keep the shared file system working at the same paths in the target, and move scheduled jobs with their applications
• Coordinate the move of the Strongmail email platform with the mail engineer
• Write and own the cutover and rollback runbooks, and lead the rehearsals, weekend cutovers and hypercare
• Support the decommissioning and data wipe of the source environment
• Lead the offshore team day to day: set priorities, review their work, and keep risks and the schedule visible
• Work closely with the client’s DevOps, DBA, security and network teams

Requirements:

• 12 to 15+ years in Linux infrastructure and data center operations, including hands-on leadership of data center migrations
• The candidate has led at least one data center exit or migration to the cloud
• 5–6 hours of daily overlap with the client's team is required
• deep hands-on knowledge of the RHEL family, including end-of-life CentOS and Oracle Linux
• working knowledge of FreeBSD
• Troubleshooting, performance tuning, and package and dependency management
• Perl 5, CPAN, Apache, cron and Make-based builds
• Reading code to find hidden dependencies such as shared paths, hard-coded hosts and database endpoints
• VMware vCenter and VM migration tooling
• Dependency mapping, wave planning, runbooks, rehearsals, weekend cutovers, rollback and hypercare
• NFS and NetApp, including moving a shared file system without changing its paths
• MySQL/Percona operations, replication, backup and restore, and moving databases with minimal downtime
• Docker (building and running images for legacy applications)
• working knowledge of Kubernetes (deployments, CronJobs, volumes)
• DNS, load balancers such as NetScaler, Cloudflare, firewall rules and IP allowlisting
• Bash, Perl, Ansible and Packer; Git and GitLab CI/CD
• AI coding assistants for code analysis and runbooks, with engineering review of every output
• leading an offshore team, writing clear documentation, and working side by side with the client's engineers
• Bachelor's degree in Computer Science or a related field
• Google Cloud experience: Compute Engine, GKE, Filestore / Google Cloud NetApp Volumes, Migrate to Virtual Machines and Migration Center
• Red Hat Certified Engineer (RHCE), Google Cloud Professional Cloud Architect or similar certification
