Software Development Engineer, Brazil Build Compute Team

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.

What You'll Do

• Own critical components of Amazon's Tier-1 build infrastructure
• Design and implement core components to power large scale NAWS-based build fleet
• Leverage AI/ML for intelligent task scheduling and resource optimization
• Scale systems handling 2-3x growth while maintaining high performance and availability
• Debug complex distributed systems issues
• Mentor teammates on operational excellence and system architecture

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

Key job responsibilities

• Design, implement, and maintain distributed systems for Brazil Build System (Tier-1) processing 25 million tasks daily
• Build next-generation NAWS-based infrastructure to harden security boundaries, scaling to 120K+ build instances
• Operate and continuously improve task dispatching (NBTM) and build execution (DockerBuildFleetNode) with 99.99% availability
• Participate in on-call rotation, solving difficult customer and operational problems while addressing root causes over short-term workarounds
• Deliver high-quality, maintainable code with comprehensive test automation (unit and integration testing)
• Review code, mentor teammates, and train new engineers on system architecture, testing practices, and operational procedures
• Work with legacy and modern technologies, making appropriate trade-offs to leave systems better and easier to maintain
• Communicate status and changes to stakeholders, keeping all informed of updates to plans and deliverables

About the team

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.
