Staff Product Designer - Systems San Francisco

The Role We're looking for a Senior Product Designer who thinks in systems — not just component systems, but experience systems. Someone who can look across a large, complex product and see clearly how all the pieces should fit together. Someone who defines the principles and patterns that make a product feel like it came from one mind, not fifty feature sprints. We are building the platform that the next generation of creative production runs on. And we want it to feel like it. What you'll do You will design end-to-end experiences: from early exploration to polished, production-ready work. You will build prototypes that show — not just tell — how something should feel. You will define interaction patterns that have never existed before, because ComfyUI is a product category that is still being invented. You will own the design system and principles that the whole team works from — not as an end in itself, but as the crystallized output of hard thinking about how the product should behave. You will define what ComfyUI feels like, at every level of detail. Your way of thinking will become the foundation every other designer builds on. Most importantly, you'll contribute in ways we can't foresee. You'll bring new ideas, new energy, new ways of seeing hard problems. You'll take what we've built and push it somewhere we couldn't get to alone. Who you are You have shipped product and owned the principles behind it. You've worked on something genuinely complex and made the complexity feel purposeful — not by removing it, but by making it navigable and intentional. You can zoom from pixel-level decisions to architectural ones and back without losing the thread. You have worked on professional tools, developer tooling, or complex creative software — products where the user is in control of something powerful and the design job is to make that power feel earned. You notice when something is slightly off and you can't leave it alone. You care about this more than you reasonably should.

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.
