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., 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.

It’s Always Day 1 At Amazon, it’s always “Day 1.” Now, what does this mean and why does it matter? It means that our approach remains the same as it was on Amazon’s very first day - to make smart, fast decisions, stay nimble, invent, and stay focused on delighting our customers. In our 2016 shareholder letter, Amazon CEO Jeff Bezos shared his thoughts on how to keep up a Day 1 company mindset. “Staying in Day 1 requires you to experiment patiently, accept failures, plant seeds, protect saplings, and double down when you see customer delight,” he wrote. “A customer-obsessed culture best creates the conditions where all of that can happen.” You can read the full letter here
