Research Scientist – TikTok Recommendation(NextGen LLM) - Global Frontier Tech Recruitment Program - 2027 Start (PhD)
About the role
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.
Project Overview, Challenges & Value
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.
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.
Unified Multimodal Semantic Space: Explore alignment across video, image-text content, and user intent, constructing a fully multimodal semantic space that goes beyond text.
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.
Key Challenges
Extreme-scale reasoning: Performance gains and bottlenecks associated with ultra-large model parameters and ultra-long sequence modeling.
Multimodal fusion: Challenges in representation learning for cross-modal intent alignment.
Autonomous evolution: Breakthroughs in long-horizon planning and decision-making paradigms for agent systems.
Qualifications
Minimum Qualifications: Individuals who are completing or have recently completed a PhD degree in Computer Science, Machine Learning, Artificial Intelligence, Statistics, or a related field.
Experience in one or more areas of computer vision, natural language processing, and machine learning.
Solid knowledge and experience with at least one major deep learning framework (e.g. PyTorch, Tensorflow, MXNet, Caffe/Caffe2).
Familiarity with deep neural network architectures such as transformer/SSM/CNN/RNN/LSTM etc.
Strong analytical and problem-solving skills.
Ability to work collaboratively in cross-functional teams.
Preferred Qualifications
Authors with publications in top-tier venues such as SIGGRAPH, SIGGRAPH Asia, CVPR, ICCV, ECCV, ICML, NeurIPS, ICLR.
