Research Scientist - World Model

THE ROLE

This is the role at the center of the thesis. Luma already trains the strongest generative video models in the industry; the next step is turning those models into world models - interactive, controllable, physically faithful, and useful as a substrate for embodied reasoning. As a Research Scientist on the World Models team, youll work on the next generation of generative models that can be rolled out as worlds.

WHAT YOULL DO

• Invent next-generation world model architectures - diffusion, transformer, autoregressive, or hybrid - with a particular focus on controllability and physical consistency.
• Develop controllability mechanisms that let an agent step into the world: action conditioning, view conditioning, long-horizon rollouts.
• Define and own the metrics: physical fidelity, long-horizon coherence, action-following, and downstream usefulness for policy training.
• Run scaling studies that tell us where compute, data, and architecture pay off.
• Publish at the frontier; contribute to the open-source release that is the long-term deliverable.

MINIMUM QUALIFICATIONS

• PhD or equivalent research record in ML, computer vision, robotics, or related fields.
• Deep expertise in at least one of: large-scale generative modeling (video/3D/world), self-supervised representation learning, model-based RL.
• Strong PyTorch and large-scale training experience - youve trained models that hit the limits of a multi-node cluster.
• A research record the field knows (top-venue publications and/or widely-used open releases).

PREFERRED

• Prior work on world models, model-based RL, generative video, neural simulation, or 4D scene representations.
• Experience using generative models for downstream embodied tasks (planning, control, evaluation).
• Excitement about open-sourcing frontier models.
