Diversity, equality and inclusion 

Our workplace reflects the qualities we want to see in the world. It’s full of skills, perspectives and backgrounds. And it’s characterised by an inclusive, welcoming and safe atmosphere. 

We provide equal employment opportunities, competitive salaries and share options. We strive to attract, nurture and retain diverse individuals. Because that’s how we do our best work. And because that’s the kind of world we want to live in.

Ways of working

London is, and always has been, the tech capital of Europe, which is why we’re proud to call it home. Work either in our Oval head office, or in our east London lab (the biggest of its kind in London). Here we work on ground-breaking technology together with inclusive talent. 

There’s an open atmosphere in our offices. We often have lunch together, go bouldering or play Nintendo Switch after hours. There are always drinks and snacks because, just as our planet needs clean energy, so do you. Even though we love the energy of working face to face, we also support hybrid working for all.
