The posting

1. 前馈式重建算法研发:负责研发基于 Transformer 先验或多视角交叉注意力机制的前馈式重建算法, 多视图几何与神经网络架构设计: 2. 负责设计高效的跨视角几何对齐、像素级对齐(Pixel-aligned)特征预测网络以及极线约束(Epipolar Geometry)机制,攻克前馈网络在未知物体与复杂场景上的泛化性(Generalization)难题。 3. 传统与生成式 3DGS 重建优化:深入优化 3D Gaussian Splatting (3DGS) 场景重建管线,针对特定工业或机器人场景,改进高斯参数初始化、致密化(Densification)策略,提升在复杂光照和弱纹理区域的重建精度。 4. 高效渲染管线与算子优化:负责 3DGS 前向与后向光栅化(Rasterization)渲染管线的底层深度定制与优化,编写高并发的 CUDA Kernel / Triton 算子,提升前馈预测与动态渲染的综合吞吐率。 5. 数据生成与 3D 资产管线构建:搭建并优化大规模多视角/3D 互动数据集(如 Objaverse, ScanNet, MVImgNet 等)的清洗与自动化处理管线,利用 Blender 或物理仿真器构建高质合成数据生成系统。

1. 毕业时间介于2026年9月至2027年8月的国内外高校的本科生、硕士生、博士生,计算机、自动化、数字媒体技术、应用数学等相关专业优先。 2. 精通 Python 和 C++,熟练掌握 PyTorch 深度学习框架,具备优秀的面向对象设计与大型分布式训练(DDP/DeepSpeed)工程能力。 核心技术背景: 3. 深入理解多视图几何理论(包括相机标定、对极几何、MVS、透视投影、SfM 基础)。精通 3D Gaussian Splatting (3DGS) 的底层数学物理原理与经典开源框架,对光栅化渲染有实际修改、性能调优或重构经验。 4. 熟悉至少一种主流前馈式或生成式 3D 架构特点(如基于 Cross-Attention 的多视角特征聚合网络,或 Epipolar-guided Transformer)。 5. 熟练掌握 Linux 开发环境,熟练使用 Open3D, Trimesh, PyTorch3D 等三维数据处理库

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
