Research Scientist - World Model

Posted 13 hours ago

Job Description

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, you'll work on the next generation of generative models that can be rolled out as worlds.

WHAT YOU'LL 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 — you've 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.
