Job Summary

Build next-generation world models for TikTok’s Vision-Applied Research team, focusing on long-horizon temporal consistency, realistic physics, and complex dynamics. Develop large-scale multimodal data generation and training pipelines for long-context interactive video generation models. Advance video generation to capture causal object interactions, and enable real-time interaction between users/agents and the model. Collaborate with cross-functional research teams and publish in top venues.

Location: San Jose

Workplace: Onsite

Employment Type: Full time

Job Function: Research & Scientific (R&D)

Key Responsibilities

•Develop large-scale, diverse, interactive multimodal data generation pipelines.
