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 engineers who want to work on distributed storage systems that serve real workloads at significant scale. You'll tackle challenges in replication, consistency, and fault tolerance. You'll operate what you build.
Key job responsibilities
What You'll Work On

• Distributed systems design: consensus protocols, replication strategies, failure handling


• Systems-level programming for storage engines and critical data paths


• Operating services at scale: performance tuning, debugging production issues, capacity planning


• Building tooling and automation that makes a small team effective at running large infrastructure

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.
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.
