Would you enjoy diving deep into, operating, and improving some of the largest software systems humanity has ever built? Do the challenges that come of driving technical, business, and cultural change to improve the reliability, performance, and efficiency excite you? The AWS Managed Operations (MO) organization was founded in April 2023, with the objective to reduce operational load and toil through long-term engineering projects. MO is building the best-in-class engineering and operations team that will own the day-to-day operations for AWS Regions; improving the availability, reliability, latency, performance and efficiency to operate AWS regions. Amazon is looking for highly motivated Senior Systems Development Engineers who can balance the day-to-day operations of AWSu2019 software systems with long-term software engineering to reduce operational toil. We need engineers who enjoy constantly learning and diving deep into the wide range of systems and technologies that make up one of the worldu2019s largest cloud providers. Amazon will provide relocation support for successful applicants relocating within the European Union. A day in the life Youu2019ll roughly spend 50% of your time operating production systems and 50% making long-term improvements to the reliability, availability, and performance of those software systems. An example week could look like: Monday morning you root caused why some deployments recently failed, and in the afternoon, you made fixes for those bugs. Tuesday you realized thereu2019s actually a common thread to those bug fixes yesterday, and designed a solution to that class of problem, seeking feedback from your team. On Wednesday you investigated a Service Level Objective (SLO) that recently became less than useful. You dove deep, talked with the partner team, and found out the thresholds no-longer makes sense, so you updated their infrastructure as code (IaC) to fix it. Then on Thursday and Friday you were developing software with your team on a system you designed which safely replaces the fleets in your teamu2019s care with a more optimal hardware type, increasing the performance whilst decreasing its carbon emissions.
