Simulation Researcher/Engineer

The Role

We're building a sufficiently faithful, controllable simulation of the world — on top of Luma's generative video and 3D models — as the substrate for training general-purpose robot policies. As a Simulation Researcher/Engineer, you'll help define what that substrate looks like. You will sit at the boundary between generative models and classical physics simulation, and you'll be one of the people who decides where each one earns its keep.

What You'll Do

• Design simulation environments that are visually rich, physically plausible, and trainable at scale — a hybrid of generative rollouts and physics-engine-based scenes.
• Build the evaluation harness that tells us whether our world model is good enough to train robots on (sim-to-real gap, physical consistency, long-horizon coherence).
• Develop differentiable and GPU-accelerated simulation pipelines where they unlock new training signal.
• Drive the asset, scene, and task generation pipelines — including using Luma's own generative stack to bootstrap diversity.
• Collaborate with world-model researchers (upstream) and policy-learning researchers (downstream).
