Biglight is an experience design agency that combines customer insight, UX and design with constant innovation and experimentation to help leading brands create remarkable customer experiences.

We’re expanding our capabilities into component library and design system development for enterprise clients. This role focuses on building and maintaining a sophisticated UI component library that powers both e-commerce and B2B web applications for a major UK brand.

You’ll be working with modern frontend technologies (Preact, Tailwind

CSS, and Storybook) to create reusable, accessible and pixel‑perfect components that form the foundation of our client’s digital experiences. The library includes 70+ components, 200+ documented stories and supports multiple themes with automated CSS generation.

This is a hands‑on development role where you’ll own components end‑to‑end: from implementation through Storybook documentation, accessibility compliance, and cross‑theme testing. Each component you build gets its own QA environment and you’ll collaborate closely with designers through integrated Figma tooling.

You’ll be working alongside the client’s product engineering team, participating in daily stand‑ups and contributing to a shared roadmap that includes UI elevation across the platform, a mobile‑first redesign, and new feature development.

This is also a client‑facing role. You’ll join client stand‑ups, take requirements directly from stakeholders, and collaborate closely with their product and engineering teams. We’re looking for someone confident in communicating with clients, comfortable asking clarifying questions and able to translate business needs into robust technical solutions in partnership with the wider team.
