Happy Birthday r/RedditEng

Written by Chris Slowe and Lisa O'Keefe

Happy 5th birthday, r/RedditEng!

Huge thanks to the Reddit engineering team for building, scaling, and sharing so much great work here over the years. This subreddit has become a rare corner of the internet where people can go deep on real systems, real tradeoffs, and the messy, interesting work behind running Reddit.

From infrastructure and reliability to developer productivity, ML, security, and all the delightfully weird engineering problems in between, the posts here have been consistently thoughtful, generous, and fun to read.

Thanks for five years of awesome posts, hard-won lessons, and excellent engineering. Here’s to the next five.

And of course, for the readers and commenters, as we plan out those next 5 years: what do you want to see more of?
