About the job

Site Reliability Engineering (SRE) combines software and systems engineering to build and run large-scale, massively distributed, fault-tolerant systems. SRE ensures that Google Cloud's services—both our internally critical and our externally-visible systems—have reliability, uptime appropriate to customer's needs and a fast rate of improvement. Additionally SRE’s will keep an ever-watchful eye on our systems capacity and performance.

Much of our software development focuses on optimizing existing systems, building infrastructure and eliminating work through automation. On the SRE team, you’ll have the opportunity to manage the complex challenges of scale which are unique to Google Cloud, while using your expertise in coding, algorithms, complexity analysis and large-scale system design. SRE's culture of intellectual curiosity, problem solving and openness is key to its success. Our organization brings together people with a wide variety of backgrounds, experiences and perspectives. We encourage them to collaborate, think big and take risks in a blame-free environment. We promote self-direction to work on meaningful projects, while we also strive to create an environment that provides the support and mentorship needed to learn and grow.

Drive the future of site reliability by designing and implementing an autonomous AI system that analyzes production alerts, investigates incidents, and intelligently executes actions to automatically resolve routine events, thereby shifting our focus to next-generation development.

Represent and protect the user experience of Google's advertising users and help grow the advertisers that partner with us by particularly focusing on the reliability and efficiency of the systems under our care.

Behind everything our users see online is the architecture built by the Technical Infrastructure team to keep it running.
