Sydney, New South Wales, Australia The 7 Day Project Full time $100,000 - $150,000 per year

We're hiring a Design Engineer (UI Systems) to redesign our web & mobile app and marketing site—then turn it into a documented, reusable system.

You're a hands-on designer who codes: you love tokens, accessible components, and clean, testable React. You'll ship a shared theme across app and site, set up Storybook "Do/Don't" guidelines, and mentor devs to keep things DRY.

Your primary responsibilities will be:

  • Redesign the app UI → audit flows, create responsive layouts, and implement accessible, performant components.
  • Revamp the marketing site → design and build a fast, SEO-friendly site on a shared brand system.
  • Ship a design system → tokens for color, typography, spacing, states, motion; document usage and edge cases.
  • Create a dev playground → Storybook (or equivalent) with Do/Don't examples, code snippets, usage guidelines, and live props.
  • Build DRY themes → light/dark + brand variants using design tokens with zero duplication across app & site.

What we are looking for:

  • 2+ years in product UI + front-end engineering (you design and code).
  • Expertise in React (Typescript), CSS-in-JS/Tailwind, and component architecture.
  • Strong Figma skills (auto-layout, variants, tokens, prototyping).
  • Experience with Storybook (or Ladle), design tokens, theming, and accessible UI patterns.
  • Ability to build responsive, mobile-first UIs with a focus on performance and accessibility.
  • Comfortable setting conventions, writing documentation, and mentoring other developers.

Why join 7DAY?

  • Be part of a small, agile startup where your impact is immediate and visible.
  • Chance to shape how customers and teams experience our product.
  • Work alongside a passionate, developer-led team building innovative software.
  • Flexible work hours - To customise your workdays, to come in earlier or later than traditional schedules. The hours you work are determined by your own self-interests, not what the company dictates; and
  • To work anywhere
