What we offer:
  • Flexible remuneration and benefits system via Flexoh, which includes: restaurant card, transportation card, kindergarten, and training tax savings
  • Share options plan after 6 months of working with us
  • Remote or hybrid work model with our hub in Barcelona
  • Flexible working hours (fully flexible, as in most cases you only have to be on a couple of meetings weekly)
  • Summer intensive schedule during July and August (work 7 hours, finish earlier)
  • 23 paid holidays, with exchangeable local bank holidays
  • Additional paid holiday on your birthday or work anniversary (you choose what you want to celebrate)
