World Model Research Scientist (Intelligent Creation) - Global Frontier Tech Recruitment Program - 2027 Start (PhD)

The Intelligent Creation – Global GenAI team focuses on applied research in Generative AI, delivering intelligent creation solutions for the TikTok platform. Our mission is to empower users to create and share high-quality content with ease. The team works on cutting-edge areas including multimodal foundation models, image and video generation and editing, efficient model design, and world models.

• Conduct research and development in generative AI and multimodal models (e.g., image, video).
• Develop large-scale foundation models (LLMs/VLMs), through post-training techniques.
• Design and build models for creative applications on the TikTok platform, driving end-to-end impact from research to production through cross-functional collaboration.
• Explore new AI-driven product opportunities and contribute to next-generation creative experiences.

• Individuals who are completing or have recently completed a PhD degree in Software Development, Computer Science, Computer Engineering, or a related technical discipline
• Proficiency in training generative AI or large models using frameworks such as PyTorch or JAX.
• Strong programming skills and solid fundamentals in machine learning.
• Strong problem-solving ability and motivation to tackle real-world challenges.
• Good communication and collaboration skills in fast-paced environments.

• Ph.D. in Generative AI, Machine Learning Systems, or a related field, or equivalent experience.
• Strong research background in one or more areas: generative AI, LLMs/VLMs, or ML systems.
• Hands-on experience in at least one of the following areas: Image/video generation and editing; VLM/LLM fine-tuning; Efficient model design and optimization; Reinforcement learning methods (e.g., RLHF, DPO, GRPO)
• Track record of research publications in conferences such as CVPR, ECCV, ICCV, NeurIPS, ICLR, SIGGRAPH, or SIGGRAPH Asia.
