Frontend Design Engineer (3D Creation)

Frontend Design Engineer (3D Creation) Location: San Francisco Bay Area Employment Type: Full-Time, Direct Hire Compensation: Flexible. Highly competitive and commensurate with experience. Candidates are encouraged to share their compensation expectations based on their skills and qualifications. About the Opportunity We are partnering with an innovative technology company that is redefining how 3D content is created. Their mission is to make 3D creation accessible to everyone by transforming traditional modeling workflows into real-time, AI-driven creative experiences. This role will focus on building the frontend experience and runtime infrastructure that enables users to generate, edit, and publish interactive 3D content directly in the browser using natural language and AI-powered tools. What You'll Do Build and enhance a browser-based 3D creation platform, including scene previews, object manipulation, camera controls, material and lighting adjustments, and editing capabilities such as undo/redo. Develop intuitive workflows that allow users to generate, refine, remix, and edit 3D content through natural language interactions. Create high-performance browser-based rendering and interaction systems using React, Three.js, WebGL, and React Three Fiber . Integrate AI-driven asset generation pipelines, including text-to-3D and image-to-3D technologies. Ensure generated assets are editable, reusable, persistent, and seamlessly integrated into the application's state management system. Optimize rendering performance, model loading, memory utilization, and cross-platform experiences, including mobile and low-bandwidth environments. Required Qualifications Strong artistic and visual design sensibilities with the ability to assess model quality, materials, lighting, composition, and overall user experience. Advanced experience with React and TypeScript , including building complex, high-performance web applications. Deep expertise in Three.js, WebGL, React Three Fiber, and Drei . Solid understanding of 3D fundamentals, including: 1) Meshes; 2) Materials and textures; 3) Lighting and cameras; 4) Animation; 5) GLB/GLTF asset formats Familiarity with generative 3D and multimodal AI technologies, including text-to-3D and image-to-3D workflows. Experience delivering production-quality 3D applications, editors, creative tools, or interactive platforms. Preferred Qualifications Experience building 3D editors, game development tools, AR/VR/WebXR applications, or interactive content creation platforms. Familiarity with tools such as Blender, Unity, Unreal Engine, Spline, or PlayCanvas . Experience with AI-powered 3D technologies such as: 1) Text-to-3D; 2) Image-to-3D; 3) NeRF; 4) Gaussian Splatting; 5) AI texture generation Contributions to production-grade Three.js applications, open-source projects, or creative coding initiatives. Knowledge of 3D asset optimization techniques, including Draco compression, KTX2 textures, LOD strategies, and mesh optimization. Understanding of modern AI-native frontend patterns, including streaming generation interfaces and asynchronous state management. Why Join?
