Pipeline Engineer (Graphics/3D)

World Labs•San Francisco, CA

About The Position

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 building a production-grade web application for 3D Gaussian Splat scene generation, editing, and publishing, and we’re looking for a Pipeline Engineer to help integrate cutting-edge research features and make them reliable, debuggable, and delightful to use. This is a high-ownership, fullstack-but-backend-heavy role that sits between R&D and frontend. You will work end-to-end across graphics/ML algorithms, backend services, and frontend UI — turning proof-of-concepts into shipped features that users can rely on. The ideal candidate enjoys making complex, messy systems work smoothly in production and improving them continuously based on both internal testing and external user feedback.

Requirements

Strong proficiency in Python, including packaging, typing, tooling, debugging, and performance profiling.
Strong literacy in core 3D graphics and computer vision concepts, such as transforms, cameras, coordinate systems, rendering, and visual artifact debugging.
Demonstrated experience taking prototypes to production, including refactoring, testing, CI/CD, versioned artifacts, and reproducibility.
Solid backend fundamentals, including HTTP APIs, FastAPI (or similar frameworks), async/concurrency basics, cloud deployment, and service reliability.

Nice To Haves

Experience with photogrammetry, 3D reconstruction, or Gaussian splat rendering pipelines.
Hands-on experience with DCC tools such as Blender, Maya, Houdini, Unreal, or Unity.
Familiarity with the GPU stack (CUDA, PyTorch), batch/queue systems, and containerization (Docker, Kubernetes).
Frontend adjacency, with comfort collaborating on React-based parameter plumbing and UX for technical controls.
Experience with production pipelines at VFX, animation, or gaming studios.
A production support mindset, including willingness to iterate on documentation, tutorials, and error messages to improve usability and reduce misuse.

Responsibilities

Bridge research and product by working closely with both graphics/computer vision researchers and frontend engineers to ship usable features.
Turn standalone Python scripts into clean, production-ready systems with clear inputs, outputs, validations, and failure modes.
Develop backend services, APIs, and tooling that expose complex 3D workflows in a reliable and scalable way.
Assist in integrations across the 3D ecosystem, including asset import/export and format conversion with common DCC tools.
