You will be a core contributor to ComfyUI Desktop, the native application that brings one of the most popular open source AI projects to millions of users on Windows, and macOS. ComfyUI Desktop is downloaded millions of times a month.
Your mission is to make that first moment magical. When someone downloads ComfyUI, you're the reason it just works. You'll build the native experience that transforms a powerful but complex tool into something that feels effortless.
Example projects include…
Building a seamless installation and onboarding experience that installs Python environments for all operating systems and GPUs supported by ComfyUI
Designing a system to back-up a user's files (models, custom nodes) to be accessible from any environment
Implementing a way to manage multiple ComfyUI environments
Smoothly integrating the desktop application with ComfyUI Cloud to unlock hybrid usage
You might be a fit if…
You've shipped a desktop application before — you know what it takes to get software onto real users' machines and keep it running smoothly
Deep understanding of Python packaging and environment management (conda, venv, pyinstaller, pip) — you've wrestled with dependency resolution, virtual environments, and cross-platform distribution
Strong understanding of desktop application lifecycle: packaging, code signing, distribution, and auto-updates across Windows and macOS
Bonus: Experience with Electron, which is our current tech stack
Bonus: Experience with ComfyUI or other node-based creative tools
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.
