AWS Migration Technical Lead

We are looking for a hands on AWS Migration Technical Lead to take ownership of a major data centre exit programme.

This is a delivery-focused technical role for someone who has personally led complex production migrations from traditional data centre environments into AWS. You will work alongside existing engineering teams, assess the automation already in place, identify what is usable and build or improve anything required to complete the migration safely and on time.

This is not an enterprise architecture, cloud strategy or programme management position. You will be expected to get into the technical detail, make practical decisions, unblock engineering teams and lead critical migration and cutover activity from the front.

The programme involves multiple production workloads being migrated in parallel, including a critical platform serving more than 100 customers. All in-scope environments must be migrated ahead of a fixed data centre exit deadline.

• Own the technical delivery of data centre-to-AWS migrations across multiple production environments.
• Work directly with engineering teams to plan, build and execute migrations.
• Review existing migration tooling and automation to determine what is production-ready.
• Extend, repair or rebuild automation where gaps are identified.
• Provide hands-on technical leadership across several parallel migration work streams.
• Establish practical technical standards without creating unnecessary governance or delays.
• Make informed decisions around migration sequencing, re-platforming and technical risk.
• Identify and resolve infrastructure, application, licensing and dependency issues.
• Support teams that are less experienced with AWS, providing guidance and technical uplift.
• Own detailed cutover planning, including networking, DNS, data, access, validation and rollback.
• Lead migration rehearsals and production cutovers.
• Ensure customer-facing production services are migrated without avoidable disruption.
• Escalate technical and commercial blockers clearly to senior stakeholders.
• Provide concise reporting on progress, risks, decisions and delivery confidence.
• Support the safe decommissioning of legacy data centre infrastructure following migration.
• Proven hands-on experience delivering complex data centre-to-cloud migrations.
• Strong production-level AWS experience.
• Previous ownership of migration delivery from discovery and planning through to cutover.
• Strong knowledge of VMware and traditional data centre infrastructure.
• Experience reviewing and improving existing infrastructure automation.
• Hands-on experience with Terraform, Ansible or equivalent automation tooling.
• Strong understanding of networking, DNS, access, data movement and rollback planning.
• Experience migrating business-critical production applications with strict availability requirements.
• Ability to assess whether workloads should be rehosted, re-platformed or otherwise remediated.
• Strong troubleshooting skills across infrastructure and application dependencies.
• Experience coordinating multiple engineering teams working on parallel migrations.
• Confidence making technical decisions under time pressure.
• Clear communication with engineers, delivery teams and senior stakeholders.
• Willingness to travel occasionally for key workshops, rehearsals or production cutovers.
• Migration of hosted software or SaaS platforms serving multiple customers.
• Experience working with public-sector, healthcare or other regulated production systems.
• Knowledge of both AWS and Azure migration environments.
• Experience supporting teams through cloud capability uplift.
• Familiarity with licensing, commercial and third-party constraints during migration programmes.

• Leads by doing rather than producing strategy documents.
• Is comfortable reviewing partially completed work and forming an independent technical view.
• Can move between high-level migration sequencing and detailed engineering problems.
• Knows when to fix, rebuild, eliminate or simplify.
• Can provide technical direction without becoming a bottleneck.
