TikTok Ads is helping to power the open internet with the best technology that connects and creates value for millions of advertisers, users, and influencers across the world, driving continuous innovation and significant impact in the digital advertising space. The Ads Infra - Serving and Foundation Team builds advertising systems and integrations that power ads from creation to delivery and the data that influences decisions along the way. This system spans multiple data centers, supports rapid product iterations, and develops key advertising features. As part of our team, you will have excellent opportunities to build the end-to-end Ads system that encompasses the complete lifecycle, including massive data gathering and processing, highly concurrent, high-performance, and highly scalable advertising delivery architecture, etc. In order to enhance collaboration and cross-functional partnerships, among other things, at this time, our organization follows a hybrid work schedule that requires employees to work in the office 3 days a week, or as directed by their manager/department. We regularly review our hybrid work model, and the specific requirements may change at any time.
