Research Engineer - 3D Reconstruction

SpAItial is pioneering the next generation of World Models through generative AI, computer vision, and physically grounded 3D environment simulation. The Research Engineer will improve 3D reconstruction methods across scene representations, reconstruction problems, optimization strategies, and evaluation, while collaborating to integrate successful methods into production systems.

Responsibilities:

• Advance the quality of 3D reconstruction, from research ideas to working methods
• Work across the full range of reconstruction problems, including geometry, appearance, materials and lighting, sparse or incomplete observations, dynamic scenes, and large-scale environments
• Build and improve reconstruction methods across the full spectrum, from per-scene optimization to feed-forward models
• Stay at the frontier of scene representations, implement new ones as they appear, and adopt or extend them where they win
• Tune losses, priors, and optimization strategies to improve fidelity, robustness, and efficiency
• Build rigorous evaluations on public and internal benchmarks, and use them to drive decisions
• Collaborate with research and engineering colleagues to bring successful methods into production systems
