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 are hiring a Senior Product Engineer who will build and ship new products powered by frontier spatial models. You'll work at the edge of what our models can do, taking ideas from early prototypes to reliable products and APIs that people use, often in weeks rather than months.
This role sits at the intersection of product, research and engineering. You'll often be one of the first engineers on a new product idea. You'll own its technical direction and how the model behaves in the product, and you'll build the evals that show whether users get results they can use.
We’re looking for someone who enjoys ambiguity, works comfortably across the stack, and wants to get new capabilities in front of real users quickly.
We're hiring the brightest minds from around the globe to bring diverse perspectives to our cutting-edge work. If you're ready to work on technology that will reshape how machines perceive and interact with the world - then World Labs is your launchpad.
Join us, and let's make history together.
Location: This role is based in San Francisco, California; we work in-person in the office 5 days a week.
Visa sponsorship: We sponsor visas. While we can't guarantee success for every candidate or role, if you're the right fit, we're committed to working through the visa process together.
Benefits: We offer generous health, dental, vision and 401K benefits, flexible PTO, paid parental leave, and relocation support as needed.

We do not discriminate on the basis of race, color, religion, sex, sexual orientation, gender identity, national origin, age, disability, genetic information, veteran status, or any other characteristic protected under applicable law.

World Labs is a spatial intelligence company building Large World Models (LWMs) to perceive, generate, and interact with the 3D world. We aim to lift AI models from the 2D plane of pixels to full 3D worlds – both virtual and real – endowing them with spatial intelligence as rich as our own.
We believe that humans are innovative, curious, and creative; science and technology are both manifestations and drivers of these impulses. Propelling AI forward with spatial intelligence will also propel forward both individuals and humanity as a whole. Toward this goal, World Labs will develop spatially intelligent LWMs that can understand and reason about the 3D world from images and other modalities. Over time, we expect to train increasingly powerful models with broader capabilities that can be applied in a variety of domains, working alongside people.
These are ambitious goals, so we are building an ambitious company to tackle them. Our team, led by co-founders Fei-Fei Li, PhD; Justin Johnson, PhD; Christoph Lassner, PhD; and Ben Mildenhall, PhD, has a strong research background, but we are not motivated by exploration for its own sake. Instead, we believe that now is a unique moment where rapid scientific progress has thinned the barrier between research and applications. We aim to seize this opportunity, focusing on the entire throughline from research to engineering to product to people.
We are bringing together the most formidable slate of pixel talent ever assembled, creating a tight feedback loop between our spatially intelligent foundation models and products that will empower our users. We invite you to learn more about joining our fast-growing team.
