Founding Design Engineer

San Francisco. Posted 3 months ago

The role

You will be the sole bar-raiser for frontend UX at an early-stage B2B SaaS company building an AI-powered pricing optimization platform. You will own the design system, define frontend patterns, and shape conversational agent interfaces.

What you will do

  • Own the design system end-to-end including design tokens, a shadcn/ui-based component library, and Tailwind CSS conventions.
  • Define and enforce frontend patterns using React Query, React Hook Form, and Zod.
  • Shape conversational agent interfaces for Slack Block Kit and Microsoft Teams Adaptive Cards.
  • Codify accessibility standards by implementing WCAG contrast rules into brand guidelines and codebase.
  • Maintain and improve frontend tooling and quality including Biome configuration and Playwright E2E test coverage.
  • Translate design intent into code using reusable component abstractions and motion.
  • Partner cross-functionally with founders and engineers.
  • Integrate AI coding tools and custom lint/agent rules into the frontend workflow.

Required qualifications

  • 5+ years building product interfaces with a portfolio of shipped features.
  • Primary ownership of a production design system or component library.
  • Deep expertise in React, strict TypeScript, Tailwind CSS, and component primitives (shadcn/ui, Radix UI).
  • Strong systems thinking.
  • Experience enforcing WCAG accessibility standards and integrating them into a living codebase.
  • Hands-on experience with AI coding tools in production workflows (e.g., Claude Code, Cursor).
  • Comfort acting as the sole frontend UX standard-setter across a company.

Nice to have

  • Experience building non-standard AI interfaces: streaming responses, generative canvases, human-in-the-loop views.
  • Experience designing and shipping conversational interfaces or chatbots for B2B end-users.
  • Familiarity with Slack Block Kit, Microsoft Teams Adaptive Cards, or CLI design patterns.
  • Experience with animation and UI state transition tooling (Framer Motion, Radix).

Benefits

  • Founding team equity commensurate with early-stage, high-ownership role
  • Direct impact on product direction and technical culture from day one
