Software Engineer, Machine Learning - Ads Infra and Ranking

Job description

Meta's Ads organization builds the systems that help businesses of every size reach the people most likely to care about what they offer. At our core, we're builders who care about shipping real value. Within Ads, the Infra and Ranking organization owns the technical foundation that makes this work at Meta's scale: the ranking models that decide which ad is right for each moment; the retrieval and serving platforms that evaluate enormous candidate sets in milliseconds; and the underlying data, training, and inference infrastructure. All of this is done while maximizing compute efficiency, ensuring reliability and privacy, and using AI to speed up development. As a Software Engineer, Machine Learning in Ads Infra and Ranking, you will lead complex engineering projects that improve how production ML systems match people with relevant ads. You will translate model-quality opportunities into reliable software and measurable improvements, working across model development, data, and serving to balance relevance with the constraints of large-scale production systems.
