Job Description

<p>At World Labs, we’re building Large World Models—AI systems that understand, reason about, and interact with the physical world. Our work sits at the frontier of spatial intelligence, robotics, and multimodal AI, with the goal of enabling machines to perceive and operate in complex real-world environments. We’re assembling a global team of researchers, engineers, and builders to push beyond today’s limitations in artificial intelligence. If you’re excited to work on foundational technology that will redefine how machines understand the world—and how people interact with AI—this role is for you.<br><br></p> <h2><strong>About World Labs:</strong></h2> <p>World Labs is an AI research and development company focused on creating <strong>spatially intelligent systems</strong> that can model, reason, and act in the real world. We believe the next generation of AI will not live only in text or pixels, but in <strong>three-dimensional, dynamic environments</strong>—and we are building the core models to make that possible. Our team brings together expertise across machine learning, robotics, computer vision, simulation, and systems engineering. We operate with the urgency of a startup and the ambition of a research lab, tackling long-horizon problems that demand creativity, rigor, and resilience. Everything we do is in service of building the most capable world models possible—and using them to empower people, industries, and society.</p> <h2><strong>Role Overview:</strong></h2> <p>We’re looking for a passionate World Builder who lives and breathes the creation of rich immersive environments.
