Amazon Web Services' Cloud Storage, AWS S3, is one of the largest distributed storage systems in the world. Managing trillions of objects in storage, retrieving them in sub-x ms, building software that deploys to tens of thousands of hosts, building applications serving billions of transactions per second, achieving 99.999999999% (you didn’t read that wrong, that’s 11 nines!) durability. These are just a few of the numbers that give you a sense of the scale of the exciting problems you will find every day working in Simple Storage Service (S3). Amazon S3 powers businesses across the globe that make the lives of consumers better daily. Whether its electronic content delivered to your home, technology that betters your remote working experience, allows you to plan travel to exotic places or simply get stuff delivered to your home. As a Software Development Engineer in S3, you get to deliver these capabilities and delight our customers through teams of talented engineers and leaders.

With trillions of objects to manage, keeping track of what is in S3 is hard. S3 Index develops software responsible for durability and availability of key-value metadata. We tackle some of the hardest computer science problems. We build systems that can handle wildly varying access patterns and unprecedented load by our customers. Managing this growth auto-magically, without the need for customers to provision capacity, is what puts the "Simple" in Simple Storage Service (S3).

S3 Index is looking for a passionate software engineer to build the next generation of S3 Index systems.

In AWS, if you build it, you own it. S3 is a highly available 7x24 worldwide service requiring dedicated support from our engineering teams. We pride ourselves on a high level of ownership in the work we do. This means we hold a high bar for test automation, verification processes, design and code reviews to ensure that our systems meet the exacting standards our customers demand. We maintain a regular on-call rotation across our teams with engineers and managers all taking part to resolve the inevitable issues that arise. We work hard to minimize getting paged in the middle of the night as we recognize that a well-rested employee is a productive employee.

We have a diverse team and drive towards an inclusive culture and work environment. Our team is intentional about attracting, developing, and retaining amazing talent from diverse backgrounds. Our team members can connect in Amazon’s 10+ affinity groups, sometimes known as employee resource groups, which bring employees together across businesses and locations around the world. These range from groups such as the Black Employee Network (BEN), Amazon Women in Engineering (AWE) and Glamazon (our LGBTQ+ community).

Upon joining S3, every employee is paired with a peer buddy who will help you to quickly come up to speed in understanding the technology we’re building, the tools we use and the business problems we’re trying to solve. We hire exceptional people and we recognize the importance of coaching others. We have a formal mentor search application that lets you find a mentor that works best for you based on location, job family, and job level. On our internal “Broadcast” video streaming website, you’ll find countless presentations by some of the brightest minds in computing discussing solutions to many of the exciting problems we’re solving in AWS today with new live-streaming videos added every week.


Creating a reliable, scalable, and flexible web service requires exceptional technical expertise, a sound understanding of the fundamentals of Computer Science, and practical experience building large-scale distributed systems. You should be somebody who enjoys working on complex system software, is customer-centric, and feels strongly not only about building good software but about making that software achieve its goals in operational reality. Come join us and help solve a challenging set of problems in a space packed full of opportunities.
