Amazon runs one of the world’s most complex eCommerce platforms, where operational efficiency directly drives profitability and customer satisfaction. Efficiency is foundational to Amazon’s DNA, reflected in the Leadership Principle of Frugality and the Flywheel strategy that lowers cost structures to accelerate growth. With the cost of operating Amazon’s global infrastructure measured in billions of dollars, achieving true economies of scale—rather than allowing scale to increase costs—is essential to sustaining our competitive advantage.

The Alloy team serves as Amazon’s central efficiency organization, leading company-wide cost optimization through intelligent and automated use of AWS resources. Our work spans thousands of internal services, enabling large-scale efficiency improvements with minimal engineering effort from partner teams. We drive optimization across multiple layers of Amazon’s technology stack, focusing on GPU efficiency infrastructure for AI/ML workloads through centralized scheduling, software performance profiling, and end-to-end storage optimization through data lifecycle management. These cross-cutting initiatives transform isolated team efforts into scalable, secure, and reusable systems that deliver sustained efficiency gains across Amazon.

As a Software Development Manager in Alloy, you will lead a team of engineers and partner with service and infrastructure teams across Amazon to identify, prioritize, and eliminate performance and efficiency bottlenecks in large-scale distributed systems. You will define the technical vision, set long-term efficiency goals, and drive execution across multiple organizations. You will collaborate closely with Principal and Distinguished Engineers to influence architectural decisions, shape company-wide optimization strategies, and deliver solutions that enhance performance at scale. Your leadership will directly impact how Amazon’s services operate globally, driving measurable cost savings in the tens to hundreds of millions of dollars annually while advancing Amazon’s commitment to operational excellence and sustainability.

In this role, you will lead the design and delivery of scalable performance engineering systems, establish and measure efficiency metrics, guide cross-organizational initiatives, and develop top engineering talent to innovate at the intersection of performance, scale, and cost efficiency.
