Senior/Staff ML Engineer, Model Integration

The Role

We're looking for someone who lives on the frontier of generative AI to join us in building the core of ComfyUI. You'll be the person who takes the newest open-source models (image, video, 3D, audio, multimodal…) and brings them into ComfyUI as first-class citizens, often within days of their release.

You are a good fit if this describes you:

• You read new model papers as they drop and have opinions about them

• You love diving deep into how models actually work under the hood

• You've ported models from research into production and gotten the outputs to match

• You know ComfyUI well, its architecture, workflows and have opinions about nodes design

• You think the gap between research and production should be as short as possible

What you'll do:

• Implement state-of-the-art open-source models to run natively in the ComfyUI core engine

• Design and build the native nodes that expose new model capabilities cleanly to users

• Work directly with our core team on architecting new features

• Partner with the custom node community and help core absorb capabilities as they mature

• Help shape where we take this technology next

Bonus: If you've worked with diffusion/LLM models before or built custom nodes for ComfyUI, that's awesome
