We are responsible for modernizing core formats infrastructure, standardized format data, drive cross-platform consistency and compliance for ad formats to reduce bugs and allow the formats team to iterate quickly and improve the developer velocity.
Our goal is to continuously improve ad formats infrastructure, with a focus on increasing developer efficiency and system reliability through tech stack modernization, scalability investments, and compliance work.
