Lead Developer / Tech Lead – Readiculous Product Team (EU-Based) Copenhagen Our vision Mrs Wordsmith’s vision is of a world in which kids laugh out loud as they learn. Our mission is to transform the way kids learn through the combination of humour, illustration, animation and gaming. We are the world’s silliest learning company. We’re all about literacy that works for kids, parents, and educators. Our curriculum-aligned products make learning to read, and reading to learn, fun and effective. The company started out life with a critical insight: that kids learn more, learn faster, and have more fun learning if the materials themselves are playful. This insight was initially manifested through a series of critically acclaimed print products that quickly became Amazon bestsellers in their category and through their own e-commerce site.. The company has moved on to develop mobile games and has big goals for its central word IP, called the WordEngine. Staffed by a creative mix of artists, writers, curriculum specialists, data scientists and game designers, and with locations in London, Copenhagen and Mexico City, the company is poised for the next level - with your help.
