Reddit's Ads Optimization group hires senior (IC4) machine learning engineers to build the auction, bidding and budgeting systems behind its ad marketplace. The role covers bid computation for CPC, CPA and ROAS objectives, budget pacing across campaigns and ad groups, and spend allocation across segments and surfaces, owned from problem formulation through experimentation and production deployment. Reddit asks for 3–5+ years operating ML systems in production, Python, Java or Go, scalable data pipelines, and deeper math and optimization skill than a typical MLE. It is remote in the United States.
