Job description

This role modernizes a large, mission-critical Microsoft estate, SQL Server, Active Directory and Windows Server workloads, moving it from Azure to AWS for a regulated financial services client. The scope for year one: 35 SQL Server VMs to migrate across mixed Windows Server versions and editions, a 77 TB primary data warehouse that must be replicated and cut over without loss, 600+ stored procedures that BI and API consumers depend on staying functional, and two Always On Availability Groups plus a custom backup-restore refresh process with no native AWS equivalent. This is a deep, hands-on Microsoft/SQL Server role not a generalist cloud position inside a PCI-scoped environment held to zero-data-loss cutover standards.

Requirements

What you will do

• Migrate SQL Server workloads from Azure VMs to Amazon EC2 and RDS, choosing the right target per workload and defending that choice.
• Rebuild Always On Availability Groups and replicate a custom scheduled backup-restore process used to populate a BI server.
• Redirect full, differential and transaction log backups from Azure Blob Storage to Amazon S3, and prove recovery works end to end.
• Migrate Active Directory Domain Services running on Azure VMs, including Okta and Entra ID synchronization.
• Manage SQL Server license portability under Software Assurance and support AWS Optimization and Licensing Assessment (OLA) reviews.
• Execute cutovers to zero-data-loss standards in a PCI-scoped, regulated environment.

Required

• Deep, hands-on production SQL Server experience: Always On Availability Groups, backup and recovery, performance tuning. This is the core of the role.
• Strong Windows Server administration across multiple versions, including failover clustering.
• Active Directory Domain Services design and migration, Group Policy, DNS, and hybrid identity with Entra ID.
• Working AWS knowledge: EC2, RDS, VPC, S3 and IAM. AWS Solutions Architect Associate or higher, or a firm commitment to certify within the first six months.
• Production-grade PowerShell automation.
• Demonstrated experience migrating real database workloads between platforms, including handling the operational consequences.
• Professional written and spoken English for daily work with an international, English-speaking team.
