Way of working

  • At Gomibo, we have a flat structure and work in multidisciplinary teams. This means that the best idea counts, no matter who says it or how much work experience you have.
  • You will work closely with our content and creation teams for figuring out the design system and with our back-end colleagues to develop the most optimal API endpoints.
  • In addition to building software, we at Gomibo also enjoy doing things together outside work, such as team-building activities and a game of ping-pong in the break.
