Software Engineer, ComfyUI Desktop
The Role
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
What is ComfyUI?
ComfyUI is the world’s leading visual AI platform — an open, modular system where anyone can build, customize, and automate AI workflows with precision and full control.
Unlike most AI tools that hide their inner workings behind a simple prompt box, ComfyUI gives professionals the freedom to design their own pipelines — connecting models, tools, and logic visually like building blocks.
It’s used by artists, filmmakers, video game creators, designers, researchers, VFX houses, and among others, teams at OpenAI, Netflix, Amazon Studios, Ubisoft, EA, and Tencent — all who want to go beyond presets and truly shape how AI creates.
ComfyUI empowers those who were not trained with the power of the brush to also be a painter, and those who are, to be a maestro.
Built for users who value transparency and control Infinitely extensible — thousands of community-made nodes and integrations
Scales from creative experimentation to production automation
Open-source, used by millions, and backed by one of the most active AI communities online
Evolving to democratize visual AI creation: empowering everyone from hobbyists to studios, storytellers, and enterprises to be more productive and creative than ever before
ComfyUI isn’t just another AI app. It’s aiming to become the operating system for visual generative AI , the foundation on which the next generation of creative tools are being built.

About Us
We are a small, intense, and well-funded team in San Francisco who push ComfyUI and its ecosystem forward. Our team comes from Stability AI and Google and many contributed to the ComfyUI ecosystem way before working here.
Our organization is flat and there is no hierarchy, only categories: dev, arts, prod, ops, etc (and no, there is no one here with the title of Member of Technical Staff, it’s long and silly for a job title).
The only thing that matters is the quality of your cultural fit and execution. We work hard and demand a lot of each other. But we have fun: everyone is here to make something meaningful that will end up being our life’s work. If this mission excites you and you view yourself as a top-tier talent, your future latent self is waiting for you at Comfy.
