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.

A day in the life

A Software Development Engineer in this role will be responsible for designing features and components, upholding best practices and quality standards, delivering high quality engineering solutions and code. You will work daily with other engineers and leadership, across S3 and our partners in other AWS organizations to prioritize the right solutions for the long-term success of S3 and AWS storage health.
