About The Team

The Intelligent Creation - Global GenAI team focuses on applied research in Generative AI, and delivers intelligent solutions to TikTok, enabling users to make and share creative content in a much easier way. The team has research groups dedicated to multimodal foundation models for content creation, image/video generation and editing, efficient modeling, and world models.

Topic Content

With rapid advances in AGI and foundation models, multimodal content creation across text, image, and especially video is undergoing a fundamental transformation. This role focuses on building next‑generation multimodal and agentic foundation models that enable intelligent, efficient, and end‑to‑end creative workflows, with a strong emphasis on video generation technologies.

You will work on cutting‑edge video generation and editing, and agentic systems, optimizing models through large‑scale training and post‑training (e.g., SFT, RL). The role also involves designing efficient model architectures and advancing reinforcement learning techniques to improve model capability, scalability, and real‑world performance in video and broader creation scenarios.

Responsibilities

• Conduct research and development in generative AI and multimodal models, with a primary focus on video generation.
• 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.
