Generative 3D Models AI Research Engineer

About the Role

As a Generative 3D Models AI Research Engineer , you will contribute to the core development of our next-generation AI 3D character platform . You will work on cutting-edge research and engineering problems at the intersection of AI generation 3D modeling, machine learning for character animation/behavior. You will help lower the barriers for creators worldwide to build intelligent, animatable, and interactive virtual characters — production-ready AI characters with personality, voice, emotion, and dynamic behavior.

Key Responsibilities

• Research and develop advanced AI models for 3D character generation (e.g., image-to-3D, text-to-3D, rigging, animation synthesis)
• Build and improve no-code/low-code AI training pipelines for defining character personality, dialogue, emotion, and behavior logic
• Optimize 3D assets and runtime performance for real-time applications in games, metaverse, AR/VR, and mobile/web platforms
• Integrate AI-generated characters with game engines (Unity/Unreal), XR frameworks, and backend APIs
• Collaborate with product, design, and engineering teams to translate research into user-facing features
• Stay up-to-date with the latest advancements in generative AI, diffusion models, NeRF/Gaussian Splatting, large language models for agents, and 3D vision
• Participate in prototyping, experimentation, and publication-level innovation where appropriate

Requirements

• Bachelor's degree or above in Computer Science, AI, Computer Graphics, Machine Learning, or related fields (Master's/PhD preferred for senior roles)
• Strong programming skills in Python and at least one of: C# / C++
• Solid understanding of 3D graphics pipelines, mesh processing, rigging, animation, shaders, or real-time rendering
• Familiarity with 3D tools/libraries (Blender Python API, Open3D, Kaolin, PyTorch3D, etc.) is highly desirable
• Experience deploying models to edge devices, game engines, or cloud APIs is a plus
• Passion for gaming, virtual characters, metaverse, AR/VR, or interactive AI experiences
• Excellent problem-solving skills, ability to work independently and in a small, fast-moving team
• Good command of English (written & spoken); Cantonese/Mandarin is a plus

What We Offer

• Opportunity to work on groundbreaking AI × 3D technology with real user impact
• Collaborative environment at HKSTP with access to talent, events, and ecosystem resources
• Competitive salary and performance bonus
• Medical & dental benefits
• Flexible working hours and supportive startup culture
• Equity / stock options (for strong contributors)
