Senior .NET Migration Engineer (Cloud Modernization)

Permanent | London (Hybrid) | Tech: .NET 10, Kubernetes, AWS, Terraform, AI Agents

Forget standard "lift-and-shift." We are completely modernizing our Back End estate, moving from a Legacy London Datacentre straight into AWS and Kubernetes using .NET 10 as our target runtime.

You will build the "golden paths," shared templates, and automated pipelines to migrate applications at scale. Best of all? You will be pairing traditional automation with AI coding agents (like Claude Code) to drive massive, automated refactoring.

• Lead the application-layer migration of Back End services to AWS & K8s.

• Design shared libraries and service templates to ensure architectural consistency.

• Build migration pipelines combining Terraform, CI/CD, and agentic AI tools.

• Partner with the Platform team on observability, networking, and security.

• Mandatory: Deep C# experience (8+ years) across .NET Core and Legacy .NET Framework, plus production Kubernetes experience.

• Cloud & IaC: Strong AWS and Terraform skills.

• Data & Auth: SQL Server proficiency and experience upgrading Legacy auth to modern token patterns.

• AI-Forward: Active daily use of AI coding tools to accelerate development.
