Software Development Engineer, Brazil Build Compute Team

Amazon • Seattle, WA

32d

About The Position

Build the infrastructure that builds Amazon. Join the Build Compute Team and
work on distributed systems processing 25 million tasks daily across 12K hosts -
powering every software deployment from Alexa to AWS.

As an SDE II, you'll solve challenging distributed systems problems at massive
scale - from optimistic concurrency and circuit breakers to AI-powered
optimization. We're building next-generation infrastructure on NAWS architecture
to harden security boundaries, scaling to 120K+ build instances across Amazon.

We're looking for engineers who thrive on making systems faster, more reliable,
and more secure at Amazon scale.

We power Amazon's Brazil Build System - a Tier-1 platform processing 25 million
tasks daily across 12K hosts (384K cores). Every AWS and SDO engineer depends on
us to transform source code into deployment-ready artifacts.

Our stack: NeverBuildTwiceManager (NBTM) handles distributed task orchestration
with JournalDB transactions, optimistic concurrency. DockerBuildFleetNode
manages containerized build execution with sophisticated resource allocation and
real-time capacity management across the fleet.

The challenge: maintain 99.99% availability at massive scale while continuously
optimizing performance, mitigating risks, and solving complex distributed
systems problems. Your code directly impacts thousands of developers and
Amazon's deployment velocity.
