About the Team

Our Search Engineering Team builds and owns TikTok's search engine, combining information retrieval with modern machine learning from NLP, CV, and recommender systems. We embrace a culture of self-direction, intellectual curiosity, openness, and problem-solving.

Data Infrastructure Team

The Data Infrastructure team owns the data layer: how billions of videos and articles are ingested and indexed, how features are computed and served, how petabytes of user actions and features become training data, and how long sequences are modeled. Every retrieval and ranking model in TikTok Search runs on data our systems produce.

We are looking for talented individuals to join our team. As a graduate, you will get opportunities to pursue bold ideas, tackle complex challenges, and unlock limitless growth.

Successful candidates must be able to commit to an onboarding date by the end of the year.
