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.
