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

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.
