Founding Product Designer

Inferact•San Francisco, CA

10h•Hybrid

About The Position

Inferact's mission is to grow vLLM as the world's AI inference engine and accelerate AI progress by making inference cheaper and faster. Founded by the creators and core maintainers of vLLM, we sit at the intersection of models and hardware, a position that took years to build. We’re looking for a Founding Product Designer to give Inferact and vLLM a distinct visual identity, sharp brand presence, and highly intuitive developer product experiences. This is a 0-to-1, full-stack design role for a creator with high aesthetic taste, deep technical curiosity, and an AI-native way of executing. You will bridge the gap between technical infrastructure and visual craft. In your first 90 days, you’ll establish our visual language across high-visibility social assets, model launch campaigns, blog graphics, and partner announcements. As we scale, you’ll transition into shaping our web surfaces, brand identity, internal tooling, and core product interfaces. You’ll work directly with founders, engineering leads, product, and marketing to build design systems that scale across open-source communities, developer tools, and enterprise platforms.

AI-native operating style, using modern AI image, design, and code generators to explore concepts rapidly and ship production-ready assets.
High technical taste and fluency, with a track record of designing for developers, technical products, or complex systems.
End-to-end execution capability—able to take a rough idea or technical blog post and independently produce polished visuals, landing pages, or product mockups without needing prescribed steps.
Ability to collaborate credibly with technical founders, engineers, and product managers in a fast-paced, high-urgency startup environment.
