Who We Are:

Twitter Revenue Experience team is responsible for all interfaces between Twitter ad products and advertisers through which most of Twitter’s $2.44B in revenue flow. These encompass desktop UI, mobile UI, and programmatic access via APIs. Our products are used by advertisers of all sizes – from the world’s largest brands and agencies to small businesses and personal brands.

We’re a truly full stack team with expertise in mobile, web, backend and data and our culture emphasizes creative problem solving, fast iteration and execution.

The Audiences & Forecasting team’s mission is to build the forecasting layer for various ad products here at Twitter. We predict unique users and impressions they can see for a given budget. We look at the past data and use various statistical and programmatic modelling to accurately calculate the future campaign performance metric (unique reach, pricing, average frequency). This team will play a critical role in building the products for our advertisers to define their target audience as well as helping them to determine and allocate the budgets.

Accurate, trustworthy forecasting is a prerequisite to be able to compete for these budgets, because advertisers need to get what they were promised.

Come build the next generation of products that empower marketers to tell the most interesting, relevant stories in the world, and make a meaningful contribution to an iconic company.
