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.

This is a mixed role where you would be working across both our main areas. We work with some of the UK’s biggest brands, including George at Asda, where we build:

• Landing pages (HTML, CSS, Vanilla JS) uploaded via their CMS (Salesforce Commerce Cloud - Demandware)
• Blog posts (HTML, CSS, Vanilla JS) managed through Wordpress
• Responsive HTML Emails

We’ve also introduced automations (Node.js, Handlebars, SASS, Gulp) to make our processes more efficient and exciting. In this role, you’ll contribute to maintaining and improving these automation projects, as well as delivering day-to-day builds (landing pages, content pages, blogs, etc).
Looking ahead, we are also exploring how emerging technologies like AI can help us take our automation further, always ensuring the code is robust, maintainable and well understood.
You’ll also be supporting our A/B testing programme, using tools like Optimizely, to create experiments that optimise client websites and drive measurable business growth. At Biglight we provide tailored learning paths, hands-on training and real opportunities to shape how we work. We will invest in your development, not just expect you to deliver
