  • Collaborate with design and product to build functional and delightful product experiences
  • Ensure the technical feasibility of UI/UX designs

What we expect from you

  • Experience with A/B testing and analyzing of results.
  • Proficiency writing unit and integration tests.

  • Diversity. Including more than 20 nationalities, we enjoy a rich mix of cultures, world views and working styles - this is more than your average tech gig: these different perspectives make sure we’re solving the right problems.
  • Balance. We want you to be happy - so go ahead! Talk food and health, exercise with others, live life and most of all, laugh! Learn what works for you and use that to help everyone.
