Software Engineer, Core ComfyUI Contributor

The Role

You will be a core contributor to open source ComfyUI, one of the most popular open source projects of our time.

Your mission is to create a world-class creative tool and workflow engine. You will architect, and implement the foundations that power our engineering organization — clean software abstractions, extensible RESTFUL APIs and Python SDK, and clean code. Decisions here have long-lasting implications, and can result in massive headwinds or tailwinds for the project, thus requiring exceptional attention to detail and thoughtful design.

Example projects include…

• Writing shared abstractions that are extensible for future changes, such as the concept of subgraphs (within a graph)
• Designing data models that can be evolved in an open source environment
• Introducing a new core type, such as VIDEO or 3D
• Partnering with product design and frontend engineers to ship user facing features that also need to work in headless environments (many users run ComfyUI as an API service).

You might be a fit if…

• Experience writing Python and maintaining APIs and SDKs used at scale
• Regularly write and review code, maintaining a high bar for each
• Care deeply about elegant software design and writing clean code
• Bonus: Familiar with ComfyUI or other node based workflow tools
• Bonus: Strong understanding of tensors, pytorch, and can contribute to implementing new models for ComfyUI
