Machine learning is at the heart of how Twitter works
It serves the tweets you see on your timeline and our ability to filter out spam and abusive content. It gives us the ability to understand what is happening on Twitter and connect like-minded people with each other at scale. We apply it in a variety of ways across the company. We have teams that build the foundational machine learning platform, and teams that build tools that enable others to deliver on our goals. If you are interested in tackling machine learning challenges, from platform to modeling to applied research, check out our career opportunities.
"Twitter has provided me all I was looking for when I was searching for a new career. The genuine people have helped me feel a strong sense of belonging. We work together for a common goal. No red tape. No silo."
