Role Overview

We are looking for an experienced Storage Migration Expert to lead large-scale data migrations from on-premise storage platforms into AWS for major enterprise transformation programmes. This role focuses on petabyte-scale data movement, replication, cutover execution and ensuring data integrity across complex environments.

Remote role with occasional on-site attendance during discovery or cutover weekends.

Key Responsibilities

• Lead data migration from legacy SAN/NAS arrays (EMC, NetApp, IBM, HPE etc.) to AWS storage services (EBS, S3, FSx).
• Develop strategies for transferring very large datasets (including replication, delta syncs, snapshots, or Snowball).
• Deliver migration cutovers during weekend/outage windows and ensure data integrity throughout.
• Create detailed runbooks, rollback plans and validation steps.
• Troubleshoot performance issues across hybrid on-prem/cloud storage environments.
• Collaborate with application, database, OS and cloud teams to plan dependencies and sequencing.

Experience Required

• Strong background with enterprise storage platforms (EMC, NetApp, IBM, HPE or similar).
• Hands-on experience migrating large datasets into AWS or another major cloud platform.
• Knowledge of replication technologies, block/file transfer tools, snapshots and cloning.
• Experience tuning performance and resolving latency/throughput issues.
• Comfortable working during cutover weekends and high-pressure migration windows.

Nice to Have

• Exposure to AWS DataSync, Snowball, Storage Gateway or similar tools.
• Understanding of storage integration patterns for emulation platforms (e.g., Stromasys CHARON).
• Experience supporting OS/database teams during large migration waves.
