World Labs is a frontier AI research and product company advancing spatial intelligence, the next frontier beyond large language models. Co-founded by Dr. Fei-Fei Li, Justin Johnson and Ben Mildenhall, the company is pioneering world models that perceive, generate, reason, and interact with virtual and physical worlds.
The company’s flagship product, Marble, transforms text, images, and video into fully navigable 3D worlds, unlocking applications across gaming, film, architecture, robotics, and immersive digital experiences. Backed by leading investors and with over $1B raised, World Labs is assembling a world-class team at the intersection of AI research and real-world deployment.
We’re looking for strong Robot Learning Engineer/Scientist to develop and advance state-of-the-art methods for developing robot policies. This role is focused on training end-to-end policies with an emphasis on sim-to-real transfer, robust performance, scalable training and inference pipelines.
This is a hands-on, research-driven role for someone working at the intersection of robotics and machine learning. You’ll collaborate closely with research scientists, ML engineers and system teams to translate robotic policy and its stack into production-ready systems.
Design and implement modern robot learning systems, including imitation learning, reinforcement learning for manipulation.
Research, prototype, and productionize robotic policies with a focus on speed, precision and scalability.
Develop and improve training pipelines for sim-to-real transfer, including domain randomization, system identification, real-sim alignment.
Collaborate with simulation and infrastructure teams to minimize sim-to-real gap and ensure learning methods integrate cleanly with real-robot deployment stacks.
Build end-to-end training and evaluation workflows for robot policies, from large-scale data generation to scale up training and evaluation.
Optimize policy performance across the stack, including training speed, inference latency, data generation efficiency to support large scale production constraints.
Diagnose failure modes in simulation and real-world rollouts, design principled solutions to improve robustness, efficiency and generalization.
Contribute to technical direction by proposing new research ideas, mentoring teammates, and helping set best practices for robot learning across the organization.
PhD in robotics, machine learning, computer science, or a closely related field is strongly preferred.
6+ years of experience working on manipulation, locomotion, robot policy training, or related areas.
Strong foundation in robotics, neural network designs, sim-real transfer.
Deep experience with robot policy designs (e.g., VLA, WAM, diffusion).
Proficiency in Python and/or C++, with hands-on experience building research or production robotic systems.
Experience with deep learning frameworks (e.g., PyTorch) and low-level robotic controller.
Proven ability to work in ambiguous, fast-moving environments and drive projects from concept through deployment.
A strong sense of ownership and engineering rigor: you care deeply about correctness, stability, and measurable improvements.
Enjoy collaborating with a small, high-caliber team and raising the technical bar through thoughtful design, experimentation, and code quality.
