Senior Video Twin Algorithm Architect

I. Position Summary As the technical core and visionary leader of the Video Twin team, you will spearhead the construction of our next-generation spatial computing platform, driving the deep integration of "Video + 3D Scene + Vision Large Models". You will conquer core technical bottlenecks including high-precision multi-source video registration, real-virtual fusion real-time rendering, and all-element spatiotemporal semantic perception. Your work will deliver ultimate spatiotemporal awareness and interactive experiences for smart cities, industrial metaverse, and intelligent security fields. II.

Key Responsibilities
• Spatial Registration & Real-Virtual Fusion: Design and optimize high-precision dynamic registration algorithms combining multi-channel videos with 3D spaces (GIS, BIM, point clouds); solve engineering pain points such as occlusion culling, lighting consistency, and real-time distortion correction.
• Cinematic Rendering Pipeline: Lead the design of real-virtual fusion rendering pipelines; achieve seamless, light-and-shadow-blended dynamic video projection effects based on Unreal Engine 5 or proprietary engines.
• Vision Large Model Application: Leverage cutting-edge foundation models (e.g., SAM, Grounding DINO, GPT-4V) to achieve precise understanding of video content, including object detection, element segmentation, trajectory prediction, and behavioral analysis.
• Edge-Side Lightweight Deployment: Overcome performance bottlenecks in fine-tuning, pruning, and real-time inference of large models under real-time video twin scenarios to enhance generalization in open-world environments.
• Multi-Modal Spatiotemporal Perception: Combine multi-source data such as RGB-D and radar-video fusion to construct unified spatiotemporal representations and semantic space models.
• Architecture Design & Leadership: Formulate the platform's long-term algorithm architecture and technical roadmap; lead the team through critical technical breakthroughs while building core patent portfolios and technical barriers. III. Job Requirements
• Educational Background: Master’s degree or above in Computer Science, Artificial Intelligence, Computer Graphics, Automation, or a related field; Ph.
D. is highly preferred.
• 3D Vision: Deep foundation in multi-view geometry; proficient in camera calibration, PnP solvers, SLAM, and SFM; hands-on project experience in video-to-3D model registration.
• Deep Learning: Proficient in the PyTorch framework; familiar with fine-tuning, pruning, and deployment of vision large models (e.g., CLIP, SAM, DINOv2).
• Real-Time Computer Graphics: Solid understanding of rendering pipelines and material systems; proficient in Unreal Engine 5 development; practical experience in video texture mapping, projective texturing, or dynamic masking is preferred.
• Project Background: Proven track record as a lead architect for large-scale, platform-level projects in digital twins, smart cities, or AR/VR, with successful commercial production deployment.
• Soft

Skills:
Outstanding technical insight and problem-solving skills with the ability to lead a team through complex bottlenecks; excellent cross-functional collaboration and communication skills. IV. Preferred Qualifications / Bonus Points
• First-author publications in top-tier international conferences such as CVPR, ICCV, ECCV, or SIGGRAPH.
• In-depth, hands-on experience with cutting-edge 3D reconstruction and 3D generation technologies, such as 3D Gaussian Splatting (3DGS) and NeRF.
• Experience building a proprietary rendering engine or a video twin product from scratch (0 to 1).
• Familiarity with Web3D (Cesium, Three.js), CityEngine, or the broader Unity development ecosystem. V.

Benefits:
• Paid Time Off : Employees are entitled to statutory holidays and paid annual leave to ensure work-life balance.
• Employee Training: Regular internal training and external learning opportunities to enhance professional skills and comprehensive quality.
• Mandatory Provident Fund (MPF).
• Extended Health Care: Hospital and surgical coverage (standard ward), additional inpatient and outpatient medical coverage, dental care benefits, and extra health check benefits.
