About Biglight
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, TailwindCSS, 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 standups 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 standups, 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.
Requirements
Who we are looking for
We're looking for a detail-oriented Frontend Component Developer with solid experience in JavaScript frameworks, component-driven development and utility-first CSS. You'll enjoy the craft of building reusable UI, taking pride in clean APIs, thorough documentation and pixel-perfect implementation.
This is a role for someone who cares about accessibility as a core requirement (not an afterthought), understands the value of design systems and can work independently while collaborating effectively with designers and other developers.
You'll be comfortable working within an established component architecture, following conventions and contributing improvements to build processes and tooling.
Key Responsibilities
Develop and maintain reusable UI components using Preact and TailwindCSS
Create comprehensive Storybook stories with interactive controls, documentation and usage guidance
Implement responsive, mobile-first designs aligned with modern frontend best practices

Ensure WCAG 2.1 accessibility compliance across all components and themes
Support a multi-theme system, ensuring components work seamlessly across different brand themes
Collaborate through branching workflows with PR-based code reviews and clear documentation

Maintain code quality through consistent formatting, JSDoc comments, and clear prop definitions
Test components across browsers, devices, and themes to ensure stability and visual consistency
Contribute to UI elevation initiatives, enhancing existing pages and flows
Collaborate on A/B testing efforts using platform tools (e.g., Sitecore)
Use analytics data (Adobe Analytics, Content Square) to inform UX decisions
Proactively identify challenges and contribute practical technical solutions
Client & Team Collaboration
Participate in daily client standups and provide clear progress updates
Gather and clarify requirements directly from client stakeholders
Work closely with internal teams (design, QA, project management) to plan and deliver work efficiently
Communicate technical constraints and solutions clearly to both technical and non-technical stakeholders
