Do you enjoy balancing being hands-on, leading by example, with helping shape strategic direction? Do the challenges that come of driving technical, business, and cultural change to improve the reliability, performance, and efficiency of one of the largest cloud providers excite you? The Amazon 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 Amazon Regions; improving the availability, reliability, latency, performance and efficiency to operate Amazon regions. Amazon is looking for a highly motivated Principal Systems Development Engineer to drive technical operational efficiency across Amazon. This role will tackle intrinsically hard problems, venturing beyond comfortable approaches when necessary. You will learn, educate, and advocate, acquiring expertise as needed, pioneer new spaces, and inspire others as to what’s possible. This role is internally focused and highly visible, demanding continuous learning, collaboration across departments within Amazon, and it will significantly impact the quality of life for both current and future customers and builders who directly or indirectly depend on Amazon's’ European Sovereign Cloud.

Utility Computing (UC)
AWS Utility Computing (UC) provides product innovations — from foundational services such as Amazon’s Simple Storage Service (S3) and Amazon Elastic Compute Cloud (EC2), to consistently released new product innovations that continue to set AWS’s services and features apart in the industry. As a member of the UC organization, you’ll support the development and management of Compute, Database, Storage, Internet of Things (Iot), Platform, and Productivity Apps services in AWS, including support for customers who require specialized security solutions for their cloud services.


A day in the life
You’ll balance your time between operating production systems and making long-term improvements to the reliability, availability, and performance of those software systems. An example week could look like: Monday you provide meaningful feedback on the most critical upcoming change whilst guiding the most senior technical talent in your organization to make more decisions without you. Tuesday you identified a major reliability risk in the interplay between systems in your care and designed a cohesive solution. On Wednesday you lead the design review with the relevant technical leaders, receiving consensus on a path forward. Thursday, you influenced your senior management to take goals and make investments to achieve that outcome. Friday, you begun developing part of that system which would have the most impact on the reliability of the overall system.
