Research Scientist, Neural Reconstruction

Waabi World depends on accurate, scalable, and efficient reconstruction of the 3D/4D physical world from real-world sensor data. As a Research Scientist in Neural Reconstruction, you will develop the next generation of neural scene-representation and reconstruction algorithms that transform sparse, noisy, and partially observed driving data into realistic and controllable digital worlds.

This role focuses on 3D/4D neural reconstruction and rendering, including 3DGS/NeRF, neural scene representation, and generalizable reconstruction models. Your work will directly power Waabi World’s ability to build high-fidelity scene assets, recover geometry and dynamics from sensor data, and support realistic simulation and rendering at scale.

You will…

• Conduct fundamental and applied research in neural reconstruction, including:
  • 3DGS / NeRF
  • Dynamic scene reconstruction
  • Feed-forward reconstruction
  • Multi-sensor scene representation learning
• Build scalable reconstruction and simulation systems for dynamic urban scenes, including vehicles, background, lighting, and long-range structure.
• Collaborate with simulation engineers to integrate models into large-scale, distributed training and rendering pipelines.
