At Twitter, we consider it our responsibility to foster a healthy global conversation, inclusive and open to everyone in the world who wants to join.

Who We Are

The mission of our Core Services team is to provide the platform that enables rapid product development at Twitter scale through powerful generic building blocks, flexible abstractions, and self-service tooling. We also build internal interfaces and tools that make it easy to access data from a variety of sources.

We not only provide expertise in scalable application infrastructure and APIs but also Improve performance for Twitter users with decreased data over-the-wire, best-available compression across the API, and widespread use of round-trip–reducing composite requests.

Working together on building and operating 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 data, as well as create tools for 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 use 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.
