AWS Cloud Migration Engineer

About the role

We are hiring an AWS Cloud Migration Engineer to move our on-premises VMware estate to native Amazon EC2, using AWS Application Migration Service (MGN). You will join a small core migration team for a 20-week program covering about 100 Windows and Linux VMs. You will run the hands-on work: replication, test launches, cutovers and post-migration tuning. You will work closely with the cloud architect, network and security engineers, and application owners.

Reports to: Migration Project Manager (day to day) and Cloud Architect (technical direction). Team: Cloud architect, 2 migration engineers, network engineer, security engineer, DBA, and application owners per wave.

Responsibilities

Discovery and assessment

• Run AWS Application Discovery Service collectors or Export for vCenter to gather inventory and utilization data
• Help map server and application dependencies and group VMs into move groups
• Check guest OS compatibility with MGN and flag unsupported systems
• Right-size VMs to EC2 instance types and EBS volume types using real utilization data

Landing zone and setup

• Work with the architect to build VPCs, subnets and security groups, including the MGN staging subnet

• Validate network paths from source VMs to AWS (TCP 443 and 1500)

Migration execution

• Build post-launch actions: remove VMware Tools, install SSM and CloudWatch agents, apply configuration
• Execute rollbacks when a go/no-go decision requires it

Post-migration

• Support hypercare: troubleshoot performance, connectivity and application issues on EC2
• Set up backups (AWS Backup), monitoring and alerts (CloudWatch), and patching (Systems Manager)

• Clean up staging resources, snapshots and decommissioned source VMs

Documentation and handover

• Write and keep runbooks, wave records and as-built documentation current
