Founding Design Engineer

🗓️ Posted 2025-12-14 San Francisco Fulltime Hybrid Design Architecture
💰 Salary Not shared 📊 Market 12,500 JPY–20,833 JPY/mo

About the Role

Design engineer who owns the full visual and interactive experience of Jinba's platform. You'll build our design system from the ground up, create motion that makes complex workflows feel intuitive, and ship production code alongside the engineering team. This is a founding design role for someone who wants to shape how enterprise users interact with AI-native software.

Responsibilities

  • ● Design and build Jinba's design system: components, tokens, patterns, and documentation
  • ● Own UI/UX for core product surfaces, from concept through implementation
  • ● Create motion design that guides users through workflow creation and execution
  • ● Write clean, maintainable frontend code (we use shadcn/ui and modern React patterns)
  • ● Collaborate directly with engineering to ship features, not just hand off specs
  • ● Establish design processes and standards as the first dedicated design hire

Requirements

  • ● DESIGN SKILLS
  • ● Strong product design sense with portfolio showing end-to-end ownership
  • ● Motion design ability: you understand timing, easing, and how animation communicates state
  • ● TECHNICAL ABILITY
  • ● Proficient in React/TypeScript; you ship your own designs
  • ● Familiar with component libraries like shadcn/ui, Radix, or similar
  • ● Understanding of design tokens, CSS architecture, and scalable frontend patterns
  • ● PRODUCT CONTEXT
  • ● Comfort designing complex interfaces: canvas editors, drag-and-drop builders, multi-step flows
  • ● Ability to simplify dense functionality without dumbing it down
  • ● STRONG SIGNALS
  • ● Design engineer or founding designer roles at early-stage startups
  • ● Built a design system from scratch at a growing company
  • ● Background combining design and engineering
  • ● Generalist: you'd rather own the whole surface than perfect one component forever
  • ● Opinionated but collaborative: you have strong taste and can articulate why
  • ● Early-stage ready: you're excited by ambiguity and building foundations others will use
  • ● We help large enterprises build automated workflows using plain English. Unlike traditional no-code tools that bolt a chat agent onto their interface, Jinba is built as a native vibe coding platform from the ground up.
  • ● YC W26. International team across SF and Tokyo. Growing fast with major enterprise contracts.
