Founding Design Engineer

About this role

Join Jinba as the first dedicated design engineer to build a world-class design system and own the full visual experience of an AI-native enterprise workflow platform. You'll write production code alongside engineers while establishing design standards from the ground up for a fast-growing YC startup.

What you'll do

• Design and build Jinba's design system including components, tokens, patterns, and documentation
• Own UI/UX for core product surfaces from concept through implementation
• Create motion design that guides users through complex workflow creation and execution
• Write clean, maintainable frontend code using React and shadcn/ui
• Collaborate directly with engineering to ship features rather than hand off specs
• Establish design processes and standards as the first dedicated design hire

What they're looking for

• Product design with portfolio demonstrating end-to-end ownership
• Design system creation and contribution
• Motion design with understanding of timing, easing, and animation
• React and TypeScript proficiency
• Component libraries (shadcn/ui, Radix, or similar)
• Design tokens and scalable CSS architecture
• Complex interface design (canvas editors, drag-and-drop builders, multi-step flows)
• Experience with developer tools or workflow/automation products
