Engineering Manager, Ads Prediction

“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.

Who We Are

Advertising is Reddit’s primary business model and we have an ambitious goal to turn it into a massive business to fund Reddit’s mission to bring community and belonging to everyone in the world. Although several large digital ad platforms already exist, advertisers are being increasingly drawn to Reddit because of our passionate communities that drive action. This large number of self-governed communities have highly-engaged users who are in an unduplicated mindset of consuming relevant information. This has created the opportunity for Reddit to build a massive and highly differentiated ads business.

We are looking for a leader at the intersection of machine learning and engineering to support the team’s mission to provide Redditors with relevant ads by understanding user intent, context and their interests. 

We are a team of engineers focused on solving hard machine learning problems in the ads prediction space. We are responsible for the core prediction models that drive clicks, conversions and much more. Projects your team may work on include:

  • Predictive models for estimating click-through, conversion and other engagement rates.
  • Building signals for predictive models from data about users, advertisers, session and content mix.
  • Embeddings for better user and content understanding.
  • Infrastructure for machine learning including training, experimentation and serving.

We face the unique challenge of delighting both the users who see our ads and the advertisers who purchase them.
