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
  • Experience building or significantly contributing to a design system
  • 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

  • Experience with developer tools, no-code platforms, or workflow/automation products
  • 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
  • Experience at companies like Figma, Linear, Notion, Retool, Vercel, or similar dev/productivity tools
  • Built a design system from scratch at a growing company
  • Background combining design and engineering

Mindset

  • 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
