Who We Are

The Geo team maintains ownership of our notion of user’s locations, points of interest, and places at Twitter. We work with large datasets and high traffic systems while protecting our user’s privacy.

We aim to help Twitter deliver great content to each user by understanding the specific places they are interested in and identifying the right content associated with each place.

Our engineers build services and tools to automate and simplify our current Geo operations, including ingestion pipelines, location calculations, and other user-facing improvements to our Geo systems.

We care deeply about:

  • Engineering excellence such as good design abstractions, API stability, best practices, and pragmatic testing
  • The incremental approach to providing customer value
  • Removing technical debt and finding ways to improve an existing system while managing risk
