AWS Technical Lead

Key Responsibilities

• Take technical ownership of datacentre-to-AWS migrations across multiple production environments.
• Work directly with engineering teams to plan, build and execute migrations.
• Review existing infrastructure, tooling and automation to determine what is ready for production use.
• Improve, extend or rebuild automation where gaps are identified.
• Provide hands-on technical leadership across several parallel migration workstreams.
• Make practical decisions around migration sequencing, rehosting, re-platforming and technical risk.
• Identify and resolve infrastructure, application, networking, licensing and dependency issues.
• Support and guide engineering teams with varying levels of AWS experience.
• Own detailed migration and cutover planning, including networking, DNS, data, access, validation and rollback.
• Lead migration rehearsals and production cutovers.
• Ensure customer-facing services are migrated with minimal disruption.
• Escalate technical and delivery blockers clearly to senior stakeholders.
• Provide concise updates on progress, risks, decisions and delivery confidence.
• Support the safe decommissioning of legacy datacentre infrastructure following migration.

Essential Experience

• Strong hands-on AWS engineering experience within complex production environments.
• Proven experience delivering datacentre-to-cloud migrations.
• Previous technical ownership of migrations from discovery and planning through to cutover.
• Strong knowledge of VMware and traditional datacentre infrastructure.
• Hands-on experience with Terraform, Ansible or equivalent automation tools.
• Experience reviewing, improving or rebuilding existing infrastructure automation.
• 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 remediated.
• Strong troubleshooting skills across infrastructure and application dependencies.
• Experience coordinating or technically leading multiple engineering teams.
• Confidence making technical decisions under pressure.
• Clear communication with engineers, delivery teams and senior stakeholders.

Desirable Experience

• Experience delivering large-scale datacentre exit programmes.
• Migration of hosted software or SaaS platforms supporting multiple customers.
• Experience within public-sector, healthcare or regulated environments.
• Knowledge of both AWS and Azure migration environments.
• Experience helping engineering teams improve their cloud capability.
• Familiarity with licensing, commercial and third-party constraints during migration programmes.

This Role Will Suit Someone Who

• 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 planning and detailed engineering problems.
• Remains calm during high-pressure rehearsals and production cutovers.
• Knows when to fix, rebuild, simplify or escalate.
• Can provide technical direction without becoming a bottleneck.
