The Role
We’re looking for an excellent, user-obsessed digital designer to join the antidisciplinary, mission-driven team in our London office. This is a great opportunity to be the first digital designer in our business, allowing you broad scope and deep ownership of the digital elements of our product.

  • Design enterprise BI analytics for our customers, and growth-led motivational screens for our agents.
  • Work with the Product Manager to test your designs with our users, agents and customers, extracting insights and adapting the user interface and experience in response.
