Senior .NET / AWS Cloud Migration Engineer

About This Opportunity

We are representing a confidential technology organization seeking an experienced Senior.NET / AWS Cloud Migration Engineer to join their engineering team. This hands-on role focuses on migrating and modernizing business-critical services to AWS, requiring someone who combines strong.NET engineering expertise with current AWS cloud experience.

You will assess existing service estates, map dependencies, define migration strategies, and execute safe production migrations with minimal downtime. This is not a lift-and-shift project—the emphasis is on incremental modernization and cloud-native engineering.

Location: Brazil or Portugal

Responsibilities

Working as part of an agile development team, you will:

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

What We're Looking For

Required:

• 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 containerized 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 unfamiliar technical estates and develop actionable migration plans
• Strong personal technical ownership with ability to explain design decisions and trade-offs you have made
• Experience working on large-scale, high-availability platforms where production downtime has significant business impact
• Experience working in Agile, cross-functional teams
• Strong verbal and written communication skills in English

Nice to Have:

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

Technical Environment:.NET, AWS, ECS, Containers, Terraform, Infrastructure as Code, SNS/SQS, NServiceBus, RabbitMQ, CI/CD, Event-driven architecture, IAM, AWS networking and load balancing, logging and observability, blue/green deployments
