Job title: Systems Engineer (Active Directory Migration)
Location: UK (Remote-first) | Occasional travel:
Manchester
Type: Contract (initially 2-3 month with possible extension).

We are hiring an experienced Systems Engineer to deliver a critical Active Directory migration within an AWS-hosted legacy estate. This work is essential to improving operational resilience and enabling disaster recovery testing across Windows-based services. You will take ownership of untangling a partially completed AD migration and leading the move to a single, well-managed Active Directory domain within our core AWS platform environment.

This role requires strong technical judgement, not just execution.

• Assess and validate the current AD setup, risks, and dependencies.
• Design the target-state AD architecture and migration approach.
• Build a new consolidated AD environment in AWS.
• Migrate identities and services using a staged approach, preserving SIDs where required.
• Migrate an initial service as a blueprint, then scale across the remaining estate.
• Ensure AD supports reliable backup, recovery, and DR testing.
• Document decisions, risks, and runbooks clearly.

• Strong hands-on experience with Active Directory migrations and consolidation.
• Deep knowledge of Windows Server and AD operations.
• Experience running Windows workloads in AWS (EC2).
• Proven ability to deliver high-risk infrastructure change safely.

• Experience migrating away from AWS Managed Microsoft AD.
• AWS disaster recovery and backup experience.
