Twitter is what’s happening and what people are talking about right now. For us, life's not about a job, it's about purpose. We believe real change starts with conversation. Here, your voice matters. Come as you are and together we'll do what's right (not what's easy) to serve the public conversation.

*Open to both Senior and Staff Software Engineers

Our team serves the data that powers Twitter core product services.  Many social relationships that are behind Twitter like Follows, Favorites, Retweets, Blocks, Mutes, and more are served by our real-time graph database service.

This role focuses on building and sustainably supporting a highly available, scalable, and reliable graph service. The Graph Storage Team stores the relationships that power Twitter. Follows, favorites, retweets are among edges served at a rate of 10s of millions of qps. Our team is expanding in size to focus on re-architecting our core technologies to help us scale to Future Twitter needs in terms of scale, development velocity, and cost. Some of the examples of these projects are complete rebuilding of our write pipeline to kafka powered architecture, redesigning our core real time service to offer complex graph structures at large scale, Migrate from bare-metal to managed clusters, hybrid cloud support on AWS, and build automated scaling for fleet auto-scaling.
