Job description

We’re working with an established SaaS company embarking on an exciting journey to reimagine how its products look, feel, and function. This is a rare opportunity to join a small, high-impact Product Design team at the very start of a greenfield project, creating a living, framework-free design system that will set the visual and behavioural standards for its entire product suite.

What you’ll be doing

• Creating Web Components (custom elements with Shadow DOM) that encapsulate structure, style, and behaviour.
• Developing reusable components and patterns that will form the UI source of truth for multiple product teams.
• Writing clear, high-quality documentation to ensure the system is easy to understand, adopt, and maintain.
• Collaborating closely with Product Designers and other stakeholders to refine and evolve the design system.

What we’re looking for

• Proven experience building UI components without frameworks, working directly with the DOM.
• Strong knowledge of Web Components, including Shadow DOM and custom elements.
• An excellent eye for detail and the ability to turn designs into faithful, production-quality interfaces.
• A solid understanding of accessibility (WCAG), semantic markup, and responsive design principles.
• Experience documenting components, usage guidelines, and interaction patterns.
• Bonus: Familiarity with design tokens and systems and working closely with design tools such as Figma.
