Team Description

Reddit is poised to rapidly innovate and grow like no other time in its history. We’re currently hiring across three distinct teams:

Ads Data Platform Team

The Ads Data Platform team builds and maintains the core data infrastructure that powers Reddit’s advertising ecosystem. They are responsible for the performant, reliable, and scalable systems that support the collection, storage, and analysis of all Ads-related data. Their work enables real-time and batch data processing, seamless data integration across systems, and intuitive access to insights for the broader Ads organization. The team also leads the development of a scalable anomaly detection framework, supporting proactive monitoring and smarter decision-making across the Ads platform.

Ads Creative Management (ACM) Team

The Ads Creative Management team focuses on the tools and systems advertisers use to create and manage their ad content. From images and videos to headlines and full post creatives, they enable efficient creative management and innovation across the campaign lifecycle. They work closely with AI teams to provide intelligent content suggestions and automation, helping advertisers launch high-quality campaigns faster and more effectively.

Brand Innovation Team

The Brand Innovation team drives the development of new ad formats that help advertisers maximize reach and brand impact. They focus on high-visibility, awareness-driven solutions that create memorable experiences for Reddit users. By delivering guaranteed placements and engaging ad interactions, they support major brand initiatives and help advertisers achieve measurable outcomes. Their work includes evolving existing formats and launching entirely new ones to keep Reddit’s ad offerings fresh and competitive.

Role Description:

This is a generalist mid-level backend position within the Ads Organization. Ads is the fuel that powers Reddit’s mission. As a backend engineer on the team, candidates might work on:

  • Microservices and APIs that power our advertiser-facing product, ads.reddit.com
  • Distributed systems that ensure the right ad gets shown to the right user at the right time

The most important skills an engineer at this level must possess are 1) coachability and an eagerness to grow, 2) deep passion for coding, and 3) excellent independent learning skills, all while operating as a fully functioning member of an engineering team.

Responsibilities:

  • Work with product managers to design and implement Ads products.
  • Collaborate closely with the platform and data teams while building new features.
  • Lead the processes needed to improve operational stability, including improving code quality, delivering dashboards and data visualizations.
