Sr. Software Engineer - Core API

San Francisco, CA

Who We Are

We provide internal interfaces and tools to conveniently and efficiently access Twitter data from a variety of sources. Our work directly impacts the lives of our users and the success of our business.

Working together to operate our own systems at hyper-growth levels is a rare and rewarding challenge.  We are a tightly-knit and supportive group that loves doing great work together, and we are looking for exceptional additions to our flock. 

What You’ll Do

You'll join our Core API team aiming to radically improve the way Twitter clients get their data. Day-to-day you'll be designing, building, and maintaining the Twitter core API infrastructure which includes GraphQL API and asynchronous event delivery system. You will work to onboard new clients, add support for new kinds of data, as well as create tools that support our engineers building the Twitter product.

Twitter GraphQL is already serving millions of queries and the asynchronous event delivery system pushes billions of events per day, and that's just the start.

You'll write user-friendly guides and documentation to make it easy for client and server engineers to start using our services, and spend time with client teams to identify where we can provide the most value.

Your work will make our apps much more data-efficient and reliable, helping Twitter reach countries with developing communications networks and allow client engineers to rapidly build high-quality products.

At Twitter, you can have a truly global impact.
