About the team:

Infrastructure Engineering consists of Network Engineering, Systems Engineering, Site Reliability Engineering and Security Engineering - together, we build core Internet infrastructure, security applications and distributed systems at scale. Our environment processes 700,000+ requests per second, across 20 data-centers and cloud infrastructure providers.

Site Reliability Engineering is responsible for growth and scale. We take an application initially developed for 100,000 users, to 50-100 million and beyond. The challenges can be significant and we own these applications end-to-end; architecture, software development, infrastructure and the operational component. At times, it may mean rewriting or refactoring of an application in order to automate everything and remove human dependency.

We are committed to getting it done... properly, the first time.
