“The front page of the internet," Reddit brings over 430 million people together each month through their common interests, inviting them to share, vote, comment, and create across thousands of communities. Come for the cats, stay for the empathy.

The Channels team within the Growth org strives to send the right message to the right user at the right time via the right channel. Our challenges include recommending relevant content to millions of people, developing new interactions on and off the platform, and deeply personalizing what and how Reddit communicates to our users.
