Who we are:
Twitter serves the public conversation by encouraging people all over the world to connect, learn, debate, and solve problems together. We believe conversation can change the world, and that’s why Tweeps (that’s what we call Twitter employees) come to work every day.
The PIE team is responsible for Twitter’s experimentation methodology and implementation as well as visualization and analysis tooling that helps teams understand user behavior. We work with product, engineering, data science, design and executive leadership to help increase our rate and quality of innovation. The team employs a wide variety of open-source technologies including Hadoop, DataFlow, BigQuery, and Beam. We are a tight-knit and encouraging group that values diversity and loves working together. We want to maintain and increase our diversity so whoever you are and wherever you come from, if you are an outstanding engineer we would be honored if you applied!
Why it matters: The PIE team owns our internal experimentation platform, DDG, which is a vital part of driving rapid innovation at Twitter. Twitter runs hundreds of experiments every day to understand the causal impact of everything from UI changes to the deployment of new machine learning models, and PIE makes this all possible!
