  • Communicate insights clearly and persuasively, driving alignment across stakeholders and ensuring data-driven decisions are widely adopted., * A chance to do meaningful, people-centric work with an international team of passionate professionals.
  • Holistic well-being with free mental health coaching sessions and yoga.

  • Employee stock options for all employees-because everyone deserves to benefit from the success they help to create.
  • 30 annual vacation days and flexible working hours.
  • Work from abroad for up to six weeks every year. Just align with your team, and then enjoy your trip.
