Research Scientist - Controlled 3D Generation

Stability.ai•Los Angeles, CA

About The Position

We're seeking a Research Scientist passionate about 3D generation, flow matching, and diffusion models. You'll help advance the frontier of controllable 3D content creation-building models that generate consistent, editable, and physically grounded 3D assets and scenes.

Requirements

PhD (or equivalent experience) in Machine Learning, Computer Vision, or Computer Graphics.
Published work on diffusion, flow-matching, or score-based generative models (2D or 3D).
Strong engineering and problem-solving abilities: experience with PyTorch, JAX, or CUDA-level optimisation.
Understanding of 3D representations (meshes, Gaussians, signed-distance fields, volumetric grids, implicit networks).
Solid grasp of geometry processing, multi-view consistency, and differentiable rendering.
Ability to scale experiments efficiently and communicate complex results clearly.

Nice To Haves

Experience generating coherent 3D scenes with multiple interacting objects, lighting, and spatial layout.
Familiarity with scene-level control (object placement, camera path, simulation, or text-to-scene composition).
Knowledge of video-to-3D, image-to-scene, or 4D temporal generation.
Background in physically-based rendering, simulation, or world-model architectures.
Track record of impactful publications or open-source releases.

Responsibilities

Conduct cutting-edge research on flow-matching, diffusion, and score-based methods for 3D generation and reconstruction.
Design and implement scalable training pipelines for controllable 3D generation (meshes, Gaussians, NeRFs, voxels, implicit fields).
Develop techniques for conditioning and control (text, sketch, pose, camera, physics) and multi-view consistency.
Analyse model behaviour through ablations, visualisations, and quantitative metrics.
Collaborate with cross-disciplinary research, graphics, and infrastructure teams to translate research into production-ready systems.
Publish results at top-tier venues and work with interns.
