Senior Research Scientist/Engineer - Neural Graphics and World Models - TikTok

About the Role We are looking for a Senior Research Scientist / Engineer to develop AI models, neural representations, data strategies, and evaluation methods for our neural graphics system.

This is a hands-on research role for candidates who combine current ML expertise with depth in 3D or graphics domain. Depending on your primary focus track, you may define research directions and build AI models, data strategies, evaluation systems, or interactive prototypes across generative modeling, world models, 3D modeling and representations, animation, simulation, and rendering.

Strong candidates combine research judgment with hands-on engineering ability: they can identify an important modeling problem, translate it into concrete research and engineering milestones, run rigorous experiments, and work with engineering teams to turn successful results into interactive, reliable engine capabilities.

Job Responsibilities - Lead research directions in one or more areas of neural graphics, world models, 3D modeling, animation, simulation, or rendering. - Develop, train, adapt, and evaluate AI models and representations for interactive graphics and world-generation systems. - Define data and evaluation strategies that connect model behavior to quality, controllability, coherence, and interactive performance. - Build research prototypes and collaborate with engineering teams to bring successful models into real-time engine workflows. - Analyze results, identify technical risks, and translate research findings into clear next steps for model, data, and system development. - Produce reproducible research artifacts, communicate technical direction, and mentor team members.
