Description

Amazon EFS provides fully managed, elastic file storage that scales from gigabytes to petabytes without provisioning or management overhead. Customers rely on it for everything from simple web serving to large-scale analytics and ML training pipelines.

We're looking for senior engineers to own and drive significant technical initiatives within EFS. You'll design systems, lead implementation across teams, and mentor engineers while staying hands-on with code. This is a role for someone who can work through ambiguous problems, make sound technical tradeoffs, and help others grow.

Key job responsibilities
What you'll work on:
- Owning the design and delivery of major subsystems or cross-cutting initiatives
- Distributed systems challenges: consensus protocols, replication strategies, failure handling
- Systems-level programming for storage engines and critical data paths
- Driving operational excellence: leading reviews, improving reliability, reducing toil
- Mentoring engineers and improving team capabilities through design reviews and code quality

A day in the life
Tech environment: Java, C/C++, Rust, Go, and internal AWS systems. You'll work across the stack, from low-level optimization to service architecture. We're investing in AI-assisted development for systems engineering and you'll help define how we use it, from code generation to operational automation.

This role includes on-call responsibilities. We take operational excellence seriously: automated remediation, thorough runbooks, and a culture of fixing root causes rather than firefighting the same issues repeatedly.

About the team
EFS is built entirely in Boston. We're working on new capabilities that expand how customers use file storage with AWS. The team operates with a customer focus, working backward from real problems to build storage infrastructure that customers depend on for their most critical workloads.
