Linux Engineer - Server Migration

Responsibilities

• Own and engineer the Linux computer platform at client during the server migration project ensuring its stability, security, and performance throughout all migration phases.
• Plan, coordinate, and execute end-to-end server migrations from the source data center to target location including physical servers, ESXi hosts, and virtual machines.
• Manage and migrate VMware ESXi environments, including vMotion, storage vMotion, and coal migrations of VMs across data center sites with minimal disruption.
• Configure, troubleshoot, and migrate iSCSI storage networks, ensuring proper connectivity, multipathing, CHAP authentication, and performance between source and target environments.
• Manage LVM configurations during migration, including volume group export/import, logical volume resizing, snapshot-based migrations, and file system integrity validation.
• Develop and maintain automation tooling to streamline migration tasks, implement, scale, and test infrastructure services for repeatable and reliable migration workflows.
• Develop and execute migration runbooks, rollback plans, and validation checklists to ensure each migration wave is completed successfully and within defined maintenance windows.
• Collaborate with internal clients and partner engineering teams across the organization to understand their needs, assess migration readiness, and deliver effective solutions.
• Contribute to the evolution and integration of modern stack components, including Kubernetes, OpenStack, and other emerging technologies as part of post-migration target architecture.
• Work closely with first and second-level support organizations to perform in-depth technical troubleshooting and resolve complex issues arising during and after migration activities.
• Develop and implement technical solutions and process improvements to enhance system reliability, efficiency, and scalability to the target data center environments.
• Manage and optimize virtualization environments using VMware (ESXi) and Red Hat OpenShift virtualization (CNV) with a focus on cross-site VM migration and re-platforming.
• Participate in the design and implementation of CI/CD pipelines for infrastructure as a code to support automated migration and provisioning workflows.
• Monitor system performance, identify bottlenecks, and implement proactive measures to ensure optimal performance before, during, and after each migration wave.
• Ensure adherence to security best practices and compliance requirements across Linux infrastructure throughout the migration lifecycle.

Skills, Qualifications, and Experience

• Bachelor's degree in science or engineering with a minimum of four years of hands-on experience in a relevant role.
• Proven experience leading or participating in large-scale data center or server migration projects including physical to virtual (P2V), virtual to virtual (V2V), and site to site migration.
• Experience with architecture, implementation, and operation of Linux-based compute environments, including deep understanding of Linux OS internals.
• Strong hands-on expertise with VMware ESXi - vSphere, including ESXi host builds, VM provisioning, vMotion, storage vMotion, DRS, HA, and cross-site ESXi and VM migration techniques.
• In-depth knowledge of iSCSI storage networking, including iSCSI initiator/target configuration, multipathing (DM-Multipath), network segmentation for storage traffic, jumbo frames, and troubleshooting iSCSI connectivity issues.
• Expert-level understanding of logic volume manager including physical volume, volume group, and logical volume management; LVM snapshots; volume group migrations (vgexport/vgimport); thin provisioning; and LVM-based backup and restore strategies.
• In-depth knowledge of advanced networking concepts (e.g., TCP/IP routing firewalls, load balancing, blank configurations for iSCSI networks) and traditional storage platforms.
• Proven experience with containerization technologies and tools, such as OpenShift, Kubernetes, and Docker, including orchestration and management at scale.
• Strong understanding of software development and CI/CD tools including Git, Subversion, Maven, and Jenkins.
• Expertise in virtualization products from VMware (ESXi) and Red Hat (OpenShift CNV) for managing compute infrastructure at scale.
• Demonstrated ability to set and achieve project goals when implementing and integrating complex technology concepts, particularly within structured migration timelines and maintenance windows.
• Proficiency in scripting languages such as Bash and Python for automation of migration tasks and system administration.
• Strong troubleshooting and problem-solving skills, with the ability to analyze complex system issues and identify effective solutions, especially in high-pressure migration scenarios.
