Full Time
3 days ago
Job summary
Our team is working to modernize and optimize critical parts of S3's data-path. We are writing new libraries and services in Rust that are being used to improve both customer and developer experience. We have launched a re-write of a core library running at S3 scale and are now leveraging that as a foundational building block for S3 and exploring opportunities in AWS more broadly.

Managing trillions of objects in storage, retrieving them in milliseconds, building software that deploys to tens of thousands of hosts, designed for 99.999999999% 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 on Amazon Simple Storage Service (S3). Amazon S3 provides a simple web services interface that can be used to store and retrieve any amount of data at any time, from anywhere on the web. It gives any developer access to the same highly scalable, reliable, secure, fast, inexpensive infrastructure that Amazon uses to run its own global network of web sites.

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.

We are looking for software engineers to lead innovation in our Amazon S3 storage request plane team and help us build the next generation of highly scaleable, fault tolerant services. We seek smart, passionate and visionary people to help us define this exciting new technology.

Responsibilities include:
  • Design, implementation, deployment and maintenance of innovative software solutions to deliver new features in performance, cost, high availability
  • Use software engineering best practices to ensure the standard of quality of all team deliverables
  • Build and implement high quality distributed system software.
  • Work in an agile environment, prioritizing most important and impactful projects
  • Collaborate and communicate in team settings
  • Mentor team members as well as build relationships with business and technical leadership
Our team puts high value on work/life balance. We recognize that the circumstances of our team members vary, and we balance work across the team so that we're all able to maintain high standards on behalf of our customers, as well as allow for rich and happy personal lives. 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 don't like getting paged outside of work hours so we work to ensure our systems are fault tolerant. When we do get paged we work together to resolve root cause so that we don't get paged for the same issue twice.

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.

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 are active 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).
