Research Scientist - Search/Recommendation/Ads-Global Tech Research Program - 2027 Start (PhD)

Responsibilities

Team Introduction: Our TikTok Data team is responsible for developing state-of-the-art machine learning models and strategies to improve user consumption experience, inspire creativity, build a fair and flourishing ecosystem.

We are looking for talented individuals to join our team in 2027. As a graduate, you will get opportunities to pursue bold ideas, tackle complex challenges, and unlock limitless growth. Launch your career where inspiration is infinite at our Company.

Successful candidates must be able to commit to an onboarding date by end of year 2027. Please state your availability and graduation date clearly in your resume.

Topic Content: We aim to integrate recommendation large models multimodal large models, and the Agentic Rec framework to fundamentally reshape the underlying content distribution logic, empowering the system with deep semantic association and autonomous planning capabilities, exploring new frontiers in algorithmic design.
1. Recommendation Large Models: Address challenges such as gradient convergence and representation drift in ultra-long behavioral sequences, enabling the system to achieve true ""logical reasoning"" capabilities.
2. Unified Multimodal Semantic Space: Explore alignment across video, image-text content, and user intent, constructing a fully multimodal semantic space that goes beyond text.
3. Agentic Rec:Develop recommendation agents with capabilities such as self-reflection, tool invocation, and long-horizon planning, driving a transformation of recommendation and content distribution experiences.
