In this role you should be comfortable with designing in HTML/CSS/Javascript and have a good understanding of UX design.

  • Translate ideas into prototypes with excellent design and intuitive user experiences.
  • Improve the product or vision by researching, sketching, prototyping and user-testing experiences.

  • Working at Parity means focusing on the stuff that counts: building of the most cutting-edge technology for the future web. Our teams enjoy a high degree of trust, freedom and autonomy to achieve that goal.
  • Because we value initiative and learning, we've defined a generous personal budget to attend conferences or skills courses of your own choosing. We think you know what's best for you!
  • Parity is a diverse company with people from various countries and we will support you with German language courses where needed.
  • Not all of us who collaborate work in the same place. Bringing the team together is something we value a lot, so we regularly go on team retreats.
