System Development Engineer II, Region Flexibility Migration (RFM)

As a System Development Engineer II, you will take ownership of key workstreams within Amazon's Region Flexibility Migration team, driving critical infrastructure migration initiatives that enable Amazon's services to operate across multiple AWS regions. You will lead the development of automation frameworks, mentor junior engineers, and make technical decisions that shape the Boost Accelerator program's roadmap. you will drive efforts aimed at optimizing memory utilization across service fleets, identifying opportunities to right-size allocations, reduce infrastructure footprints, and preserve capacity to support continued growth and expansion. Join a team where you will have a direct impact on reducing migration burden for service teams and delivering zero-impact migrations at 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.
● Lead migration projects from planning through execution, including infrastructure setup, data replication, traffic management, and post-migration validation
● Identify and implement cost optimization strategies to reduce per-offering costs of the Boost program through automation and streamlined operations.
● Drive technical decisions for Boost program offerings, including pipeline infrastructure setups, DDB replication, containerization solutions, and new offerings such as RDS, DocumentDB, and VFI builds.
● Mentor and guide junior engineers, conducting code reviews, providing technical direction, and fostering a culture of operational excellence within the team.
● Lead root cause analysis for high-severity incidents, implement preventive measures, and drive operational improvements across the team's processes and tooling.
● 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
A day in the life
You will lead the technical direction for 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. You'll also mentor team members, participate in design reviews, and collaborate with Seattle-based leadership on strategic priorities.
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).
