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.

Who We Are

The mission of our Core API Team is to provide the platform that enables rapid product development at Twitter scale through powerful generic building blocks and highly reliable, performant and flexible abstraction.

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, robust GraphQL queries 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 exciting challenge. We are a distributed, 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 client applications get their data. Day-to-day you'll be designing, building, and maintaining the Twitter core API infrastructure which includes GraphQL API and an asynchronous event delivery system. You will work to onboard new clients, add support for new data and enhance the platform with additional features.

You will analyze memory and performance issues and improve the GraphQL query performance as we serve 100s of thousands of requests per second. You will identify gaps in metrics, tracing, monitoring and improve load testing frameworks, tracking utils and other CLI tools to drive operational excellence. You will also work to onboard new feature developers on the API platform. 

Twitter GraphQL is already serving billions of queries per day,  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.
