Position Summary
We are seeking a Systems Engineer to support the migration of Windows-based workloads from an on-premises datacenter to AWS. This onsite role will work closely with infrastructure, application, networking, and security teams to assess existing systems, prepare migration plans, execute workload migrations, and provide post-migration support.
The ideal candidate brings hands-on experience administering Windows Server environments, managing VMware infrastructure, and deploying and supporting Amazon EC2 instances. Citrix experience is a plus.

Key Responsibilities
  • Assess and document existing Windows servers, VMware virtual machines, application dependencies, and infrastructure configurations.
  • Support migration planning, including workload readiness assessments, migration sequencing, cutover procedures, validation criteria, and rollback plans.
  • Prepare AWS EC2 environments and migrate workloads in coordination with cloud architecture, networking, and security teams.
  • Administer and troubleshoot Windows Server environments, including operating systems, services, patching, storage, and connectivity.
  • Manage VMware vSphere, ESXi, and vCenter environments throughout the migration.
  • Validate server functionality, connectivity, performance, monitoring, and backup coverage following migration.
  • Troubleshoot migration issues and provide post-cutover stabilization support.
  • Maintain system documentation, migration runbooks, configuration records, and knowledge-transfer materials.
  • Follow established change management, security, and operational procedures.

Required Qualifications
  • Hands-on systems engineering or infrastructure administration experience in enterprise environments.
  • Strong Windows Server administration and troubleshooting skills.
  • Experience managing VMware vSphere environments, including ESXi and vCenter.
  • Practical experience deploying, configuring, and supporting AWS EC2 instances.
  • Working knowledge of AWS networking and access controls, including VPCs, subnets, security groups, and IAM.
  • Understanding of Active Directory, DNS, Group Policy, TCP/IP networking, and server storage.
  • Experience supporting server migrations, infrastructure transitions, or datacenter consolidation initiatives.
  • Ability to troubleshoot issues across operating systems, virtualization, networking, and cloud infrastructure.
  • Strong documentation, communication, and cross-functional collaboration skills.
  • Ability to work onsite at the designated location and participate in scheduled migration cutovers or maintenance windows.

Preferred Qualifications
  • Experience supporting Citrix Virtual Apps and Desktops, including supporting infrastructure and application delivery.
  • Experience with AWS Application Migration Service or similar migration tools.
  • PowerShell scripting and automation skills.
  • Familiarity with backup, recovery, monitoring, and security tools across on-premises and AWS environments.
  • Relevant AWS, Microsoft, VMware, or Citrix certifications.

Success Measures
  • Assigned workloads are migrated and validated within approved migration windows.
  • Post-migration issues are resolved promptly, with minimal disruption to business operations.
  • Migration runbooks and operational documentation are complete and accurate.
  • Migrated systems are successfully transitioned to ongoing support teams.
