AWS is seeking a Systems Engineer to build and operate services for our customers, to automate service operations and deployment methods, and provide mentoring for junior team members. You will be working in a large-scale, high availability environment, building and operating critical Access and Identity services for our customers.

This exciting role is designed for someone with a strong engineering background and a passion for driving efficiency, quality, and process improvements within our service operations. We are an operations team, but a key focus is driving automation to increase ops efficiency. You will have the opportunity to utilize AI tooling and to build your own solutions that automate away manual tasks.

As a Systems Engineer at Amazon you will utilize your Linux skills to troubleshoot, innovate fixes and workarounds, keep software up-to-date, and provide data and metrics that help manage the capacity and efficiency of our services. You will draw on your networking knowledge to identify and troubleshoot network connectivity issues. Our Systems Engineering roles enable engineers to develop a broad range of skills; our engineers take ownership and gain knowledge across a complex technology stack.
