San Francisco / New York / LA / Remote

“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.

As an engineering manager you will support the team that owns our core ad serving systems, including auction, pacing and core data pipelines. The past few years have seen terrific growth in our advertising business and we plan to continue that trend. We must continuously uplevel our ad serving systems to meet the needs of a sophisticated marketplace while simultaneously balancing the needs of our users and advertisers.

How You Will Have Impact

Advertising is Reddit’s primary business model and we have an ambitious goal to turn it into a massive business. 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 have spent the past few years building the foundations of a modern ad serving system, building features to help brand and performance advertisers find their audiences on Reddit and get high ROI on their ad spend. We’re now ready to build differentiated products on top of those foundations, learning from the best how to marry auction theory, machine learning and good old-fashioned distributed system design to build a massive-scale platform that works on behalf of our customers.

Reporting to the Director of Ad Serving and Marketplace, you will work closely with product managers, data scientists and the rest of the Ads Engineering teams to build the next generation of our ad serving platform.

What You’ll Do:


You will own the execution of your team’s roadmap and be accountable for consistent, predictable delivery. You will ruthlessly prioritize both planned projects and emergent asks. You will coach Tech Leads on project management and empower your team to execute autonomously. You will identify risks and proactively communicate them both internally and externally.


Ad Serving will grow aggressively during your tenure at Reddit, and our engineering managers are directly responsible for scaling up their teams. You will identify your team’s needs, write job descriptions, source, interview, and sell candidates. You will have the support of our incredible recruiting team to bring diverse and talented engineers into Reddit.
