About this role

The Role

We're looking for someone who loves optimizing model inference to join us in building the core of ComfyUI - the most complex and bleeding-edge part of our engine. You'll be working on making AI models run faster and more efficiently than anyone thought possible.

You are a good fit if this describes you:

  • You geek out about model inference, torch optimizations, and memory management

  • You've written production PyTorch code that pushes performance boundaries

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

  • You get excited about making insanely optimized code that just works

  • You think the current state of ML deployment could be way better

What you'll do:

  • Build and optimize the core inference engine that powers ComfyUI

  • Make massive models run faster and use less memory than anyone else

  • Work directly with our core team on architecting new features

  • Tackle the hardest technical problems in the visual AI space

  • 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
