Your missions

You will work in multidisciplinary teams, of effective sizes in an decompartmentalized environment where collective intelligence is a powerful driving force.
Even if you are not involved in the entire product cycle, you will see the results of your work materialized and will be able to exchange with users.
Because we believe that humans can only be accomplished in an environment where they feel good, we attach importance to our work environment and the balance between private and professional life:

  • Our way of working increases the freedom of personal organization.
  • COSE is ideally served by public transport (T8, T11 Express, Line H)
