As a System Development Engineer, you will play an essential part in Amazon's Region Flexibility Migration team, executing critical infrastructure migration initiatives that enable Amazon's services to operate across multiple AWS regions. You will work on large-scale migration projects, build automation tools, and ensure operational excellence while supporting the RFE Boost Accelerator program. In addition, you will contribute to efforts aimed at optimizing memory utilization across service fleets, helping reduce infrastructure footprints, and preserve capacity to support continued growth and expansion. Join a team focused on reducing migration burden for service teams and delivering zero-impact migrations at a massive scale. Key job responsibilities - Design, implement, maintain, and deploy components that solve problems in a complex ecosystem. We work in lots of different languages (not limited to, but most often Python and Java). It is more important to us that you understand coding in the context of working in distributed systems and/or widely scaled web applications. - Execute migration projects including infrastructure setup, data replication, traffic management, and post-migration validation. - Monitor system health, troubleshoot issues, and respond to operational events during migration activities. - Build and enhance the Boost program offerings, including pipeline infrastructure setups, DDB replication, and containerization solutions. - Develop operational runbooks, documentation, and standard operating procedures for migration workflows. - Collaborate with service teams across Amazon to identify and resolve migration blockers. - Participate in on-call rotations to ensure operational support for critical migration activities. - Conduct root cause analysis for incidents and implement preventive measures to improve operational excellence A day in the life Your focus will be on solving complex migration challenges using AWS technologies and modern development practices. You might collaborate with our Boost program team on pipeline infrastructure setups, build AI-assisted workflows that streamline migration operations, or develop tools in Python and Java to automate critical migration tasks. You'll work closely with service teams across Amazon to identify and resolve migration obstacles, analyze memory efficiency across service fleets, and contribute to expanding our Boost program offerings. Your work will span infrastructure setup, data replication, traffic management, and post-migration validation—all while supporting operational excellence through monitoring, troubleshooting, and continuous improvement. About the team The Region Flexibility Migration (RFM) team is part of Amazon's Intelligent Cloud Hosting (ICON) organization. The RFM team was formed in 2024 with the purpose of proactively discovering and mitigating issues that service teams would encounter when migrating services across AWS regions like eu-south-2 and eu-central-1. During the last year and a half, the team has developed expertise in identifying these issues and leveraging those findings to save builder effort. The team has also developed expertise in identifying undifferentiated work within these migration workloads and created the Boost program that reduces the migration burden for service teams by offloading foundational and undifferentiated migration work to a central team. In 2026, the RFM team structured its work across four themes: Region Flexibility Beyond ExitDUB, Optimizing Boost costs, Improving Boost’s customer experience, and Operational Excellence and Operational Support (KTLO). ### Basic qualifications - Experience in automating, deploying, and supporting infrastructure - Experience programming with at least one modern language such as Python, Ruby, Golang, Java, C++, C#, Rust - Experience with Linux/Unix - Bachelor's degree in Computer Science, Computer Engineering, Systems Engineering, Electrical Engineering, or other related discipline - Experience on highly concurrent, high throughput systems and knowledge of complex distributed systems ### Preferred qualifications - Experience with CI/CD pipelines build processes - Knowledge of and proficiency in the use of Python scripting language - Knowledge of best practices for software deployment - Knowledge of distributed, multi-tiered systems, algorithms, and relational databases Our inclusive culture empowers Amazonians to deliver the best results for our customers.
