Front-end developer with accessibility experience

Help us build the future of reading!

Jellybooks is looking for an experienced JavaScript and front-end developer who understands and is skilled at designing for diverse accessibility requirements.

Two years ago, our multi-national team created the Jellybooks Cloud Reader. Since then we have worked with publishers and bookshops across Europe to bring simple, one-click, file-free reading to readers across the world.

A major initiative we are launching in Janaury 2021 is a national, cross-industry platform for ebook excerpts and audiobook snippets allowing British and Irish bookshops and publishers to embed the first five to twenty percent of a book in websites, emails, and social media posts.

Jellybooksis also working on open access challenges for textbooks, early testing and reviews of newly published titles, marketing and retail challenges in bookselling and much more. We have a passion for using data to create better experiences for readers.

The new team member will help us take the Jellybooks Cloud Reader to the next level: improved functionality, offline reading and better support for diverse accessibility requirements.
