Requirements
• Shipped applications with significant real-world traffic or user counts. • Experience leading technical initiatives and shipping scalable, high-performance web and desktop applications. • Strong expertise with modern front-end tooling. (TypeScript, CI/CD pipelines) • Expertise in optimizing complex UX interactions in web and desktop applications. • A passion for creating fast, accessible, and beautiful user experience. • Startup mindset: you thrive in fast-moving environments, take ownership, and love solving problems at scale. • Comfy (https://www.comfy.org) is the AI creation engine for visual professionals who demand control over every model, every parameter, and every output. The most powerful workflow engine for visual AI. • Unlike tools that hide everything behind a prompt box, Comfy lets you connect models, processing steps, and outputs on a canvas where every decision is visible and every step is inspectable. It gives you the building blocks to create workflows nobody's imagined yet, and share them with everyone. • What started as an open-source project in 2023 now has 4 million users, 60,000+ community-built nodes, and 150,000+ daily downloads. It's used by artists, filmmakers, game studios, designers, researchers, and VFX houses, including teams at OpenAI, Netflix, Amazon Studios, Ubisoft, EA, and Tencent. • We're a small, intense team in San Francisco. Our team comes from Stability AI and Google, and many contributed to the ComfyUI ecosystem long before working here. Low ego, high ownership. We work hard and demand a lot of each other, but we have fun. Everyone here is building something meaningful that will end up being our life's work. • If this mission excites you and you view yourself as top-tier talent, your future latent self is waiting for you at Comfy. • Check out our Github (https://github.com/comfyanonymous/ComfyUI) and blog (https://blog.comfy.org). We recently raised $30M at a $500M valuation. The round was led by Craft, with participation from Pace Capital, Chemistry, TruArrow, and others.
