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:

Discovery is committed to building geographically distributed teams and we welcome applicants across the US/Canada to apply. 

Twitter's Discovery teams are dedicated to getting the majority of the world to find and participate in all that is happening on Twitter. We are composed of many teams across the company, including Product, Engineering, Design, and Data Science. We are in charge of features like new user sign-up flow & education, personalized recommended notifications, re-activating returning users, and much more.

The charter of the whole Discovery team involves work in areas such as machine learning, applied data science, recommendation systems, distributed systems, and information retrieval systems, all applied at a large scale. However, to realize those gains, it’s critical for our product engineers to utilize those platforms and systems, build out user-facing features and test it out using online experimentation. Discovery has been a major contributor to Twitter’s growth and continues to expand its impact on users through the great collaboration between our ML engineers, infrastructure engineers and product engineers.
