The posting

SUMMARY:

We are looking for an experienced Senior .NET/AWS Cloud Migration Engineer to join a highly skilled engineering team migrating and modernising complex, business-critical services to AWS.

This is a hands-on engineering role for someone who combines a strong .NET software engineering background with current, practical AWS experience.

You will work across an existing service estate, understand applications and their dependencies, define migration approaches, and help move services safely into a modern, cloud-native AWS environment.

This is not simply a lift-and-shift project. The focus is on incremental modernisation, cloud-native engineering and safe production migration with minimal or zero downtime.

WHAT WILL YOU BE DOING:

As part of an agile software development team, you will:

  • Assess existing .NET services, infrastructure, integrations, data stores and operational dependencies.
  • Map service dependencies and identify the appropriate sequencing and approach for migration.
  • Design and implement cloud-native solutions within AWS.
  • Containerise and operate services using AWS ECS.
  • Build and maintain infrastructure using Terraform and Infrastructure as Code (IaC).
  • Work with event-driven and asynchronous architectures using technologies such as SNS, SQS, NServiceBus and RabbitMQ.
  • Plan and execute incremental migration waves rather than relying on traditional lift-and-shift approaches.
  • Design safe migration and cutover strategies for business-critical services.
  • Implement approaches such as blue/green deployments, parallel running, progressive traffic switching and rollback strategies.
  • Solve complex migration challenges involving shared databases, authentication, legacy dependencies and service-to-service integrations.
  • Work closely with engineering teams and stakeholders to identify dependencies, risks and delivery priorities.
  • Improve automation, observability, documentation and overall operational readiness as services move into AWS.

WHAT WE ARE LOOKING FOR:

  • Strong professional experience developing and operating production systems using modern .NET.
  • Recent, hands-on commercial experience with AWS.
  • Direct experience migrating production applications or services into AWS.
  • Strong practical experience with AWS ECS and containerised workloads.
  • Current hands-on experience with Terraform and Infrastructure as Code.
  • Strong understanding of event-driven and asynchronous architectures.
  • Production experience with SNS/SQS or comparable messaging technologies.
  • Experience delivering complex migrations involving multiple interconnected services and dependencies.
  • Strong understanding of CI/CD, automated deployments, rollback strategies and production readiness.
  • Experience executing production migrations where downtime was unacceptable or heavily restricted.
  • Ability to quickly understand an unfamiliar technical estate and turn discovery into an actionable migration plan.
  • Strong personal technical ownership; you should be comfortable explaining what you personally designed, implemented and changed, including the decisions and trade-offs you made.
  • Experience working on large-scale, high-availability platforms where production downtime has significant business impact.
  • Experience working in an Agile, cross-functional team
  • Strong verbal and written communication skills in English

TECHNICAL ENVIRONMENT:

You will be working with technologies and concepts including:

  • .NET
  • AWS
  • ECS
  • Containers
  • Terraform
  • Infrastructure as Code
  • SNS / SQS
  • NServiceBus
  • RabbitMQ
  • CI/CD
  • Event-driven architecture
  • IAM
  • AWS networking and load balancing
  • Logging, monitoring and observability
  • Blue/green and zero-downtime deployments

Experience with New Relic would also be beneficial.

NICE TO HAVE:

  • Hands-on experience with NServiceBus.
  • Experience with RabbitMQ.
  • Experience with New Relic.
  • Previous experience modernising complex or legacy .NET service estates.

WHAT’S IN IT FOR YOU?

  • Be part of our collegial environment where responsibility and authority are shared equally amongst colleagues and help create our company culture.
  • A culture in which we don’t criticise failure but ensure we learn from our mistakes
  • An Agile environment where your ideas are welcome
  • The possibility to grow and experience different projects
  • Ongoing Training & Mentoring
  • The possibility of travelling
