Who We Are:
SREs work on improving the availability, scalability, performance and reliability of Twitter’s production services. Come join us.
What You’ll Do:
As a Site Reliability Engineer for the Mesos/Aurora Team at Twitter you will be working to improve the reliability and performance of the compute platform that underlies most of the services that run Twitter. You will work shoulder-to-shoulder with our engineering teams to design and build the next generation of cloud and systems infrastructure, focusing on automation, availability and performance, and above all efficiency at ‘reach every user on the planet’ scale.
Our core infrastructure receives hundreds of millions of tweets per day and serves tens of billions of API requests. We also serve over 2+ billion search queries per day, render hundreds of millions of ad impressions, and process hundreds of terabytes of log and interaction data daily.

• Participate in code reviews for projects primarily written in Java and Scala, built on open source libraries such as Finagle, and running on both physical and virtualized platforms.
• Represent the SRE organization in design reviews and operational readiness exercises for new and existing services.
Who You Are:
• Solid understanding of systems and application design, including the operational trade-offs of various designs.

Desired:
• Practical experience in Java or Scala.
