Software Development Engineer, Efficiency & Performance, Alloy - Amazon

Description In eCommerce, we operate in an ultra-low-margin business. Our ability to operate efficiently makes the difference between profit and loss, or between prices a customer is happy or displeased with. It is at the core of our business DNA, enshrined in both the Leadership Principle of Frugality and the Amazon flywheel (lower cost structure). The costs of running the Amazon website are now measured in billions of dollars, and it is our collective responsibility to ensure that we are realizing an economy of scale, rather than having scale kill our economy. The Alloy team is a central efficiency team which drives cost savings for all service teams within Amazon via efficient use of AWS resources as they build and operate their services. This team is special in 3 ways (1) business impact - we have proven records to save cost by hundred million dollars annually. We have earned trust and reputation from service teams, partner teams (business and technical), and senior leadership (2) technical complexity - our system is not a single product but the whole Amazon. We create central efficiency solutions which save costs for thousands of internal services with minimal or zero efforts from their engineers; (3) professional network - we work with a group of Principal Engineers and Distinguished Engineers closely. Working with brilliant people helps you grow your career. We are standing up a new central Performance Engineering team to expand our scope from hardware utilization (unused resources) to software optimization (used resource), via profiling with central fixes, proper upgrade of library, central scheduling from resource pools, etc., In addition, we are expanding our scope from compute to storage resources, such as auto migration to cheaper storage classes, removal of duplicates and unused data, applying proper data retention policy, logging with proper compression format, etc. We are also building a large resource sharing infrastructure to maximize the utilization of scarce GPU resources. While a lot of these are common techniques for individual teams, how to create a central, safe, and scalable solution to reduce their undifferentiated efforts is the amazing part of this team!
