Key job responsibilities

The services you will own are the foundation of S3, and managing them at the scale of S3 provides challenging technical problems that you will solve. That scale provides leverage for your work to improve the experience of many customers, and you will tackle some of the most difficult problems in S3 head-on. You will be responsible for the design and implementation of new components and improvements to services within our space, and will work with other engineers on your team to deliver.

A day in the life

A typical day for an SDE in S3 Storage is based around writing code and solving problems at scale. On any given day, you may spend time delivering features and fixing bugs, add testing to existing code, improve operational tooling, collaborate with senior engineers to design new components that shape the future of the system, and build expertise in specific areas of the service and grow to be a subject matter expert in your domain.

Occasionally, you will be involved in operational investigations to resolve and root cause customer impacting issues, as well as write documents outlining your solution to complex problems. In addition you will leverage gen AI to automate many of the root causing reducing manual operator involvement.
