Job Description

21 Buttons is changing the fashion game - through technology and talent. It has become the leading fashion social network in Europe where more than 7 million users come to get inspired by their favourite influencers and friends’ ready-to-shop content. With over 10 million outfits shared, 21 Buttons allows anyone no matter their audience size to earn revenue from sharing their personal style.

Launched in our first country just over 3 years ago and now with more than 3000 influencers across the US, UK, Germany, France, Italy and Spain, we’re growing faster than ever and now are keen to find someone as passionate as we are about our project to join the team at this exciting stage of our company’s journey of propelling our ambition of Stateside expansion.

Although our focus is fashion, 21 Buttons is an engineering company. We are looking for talented people with a broad set of technical skills who are ready to tackle some of the technology's greatest challenges and make an impact.

Our Engineering & Technology team kick-ass in the development of an innovative product that will be used by (hope!) billions of users.
