Generative AI Researcher (3D, Video, and Agentic Intelligence)

About the role

Lightspeed Studios is a business unit of Tencent focused on advancing game development through stories, gameplay and advanced technology, and its hiring team is the Lightspeed Tech Center, an R&D department under Lightspeed Studios that develops PUBG Mobile and other games. The role is to build generative AI systems for next-generation game development.

Key responsibilities

• Develop AI systems for 3D object and scene generation, video generation (world modeling), human motion capture and generation, multimodal vision-language models (VLM) and agentic reinforcement learning systems.
• Conduct original research in computer vision, computer graphics and embodied intelligence to drive innovation in generative AI pipelines for virtual world creation.
• Collaborate with game developers, artists and designers to integrate AI-generated content into gameplay.
• Explore and apply the latest research trends in 3D generation, video understanding, multimodal reasoning and simulation-based RL to improve production efficiency and creativity.

Required profile

• PhD in Computer Vision, Computer Graphics, Machine Learning, Robotics or a related field.
• Strong research background in at least one of: 3D object or scene generation, video generation / world modeling, human motion capture or generation, VLM, or reinforcement learning / agentic AI.
• Publications in top-tier conferences or journals such as CVPR, ICCV, ECCV, SIGGRAPH, NeurIPS, ICML, ICLR, PAMI, IJCV, TOG or TVCG.
• Excellent teamwork and communication skills in a fast-paced, research-driven environment.

Required skills

• Proficiency in deep learning frameworks such as PyTorch or TensorFlow, with experience in large-scale model training or evaluation.
• Preferred: hands-on experience with 3D modeling or rendering tools (Blender, Unreal Engine, Unity), strong coding in Python, C++ or similar, familiarity with 3D, motion or video generation datasets and benchmarks, and proven ability to turn research into interactive applications.
