Research Engineer / Scientist (Robot Learning)

Job description

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.

Job responsibilities

  • 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.

Job requirements

  • 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.
