- Perform migration readiness checks before each scheduled migration wave.
- Validate network bandwidth headroom and replication concurrency requirements.
- Confirm data-freeze requirements and server tagging before migration.
- Execute production cutovers under client direction and approved procedures.
- Support rollback activities when migration or cutover issues arise.
- Contribute technical evidence for migration go/no-go decision meetings.
- Review AI-generated migration artefacts for technical accuracy and completeness.
- Validate migration documentation instead of simply accepting automated outputs.
- Troubleshoot replication, connectivity, Windows, Linux, and migration-related issues.
- Work hands-on with AWS Application Migration Service (AWS MGN).
- Support large-scale block-level server replication and migration activities.
- Administer Windows Server environments throughout the migration lifecycle.
- Provide Linux administration support for migration-related activities.

- Candidates with partial AWS migration exposure may also be considered.
- Resources who are technically strong and fast learners are encouraged.
- Suitable candidates can be trained intensively on AWS migration technologies within 7 - 10 days.
- Priority will be given to candidates demonstrating strong learning ability, troubleshooting skills, and infrastructure fundamentals.
