The Sulitest movement is strongly supported by major national and international NGOs and organizations (i.e. the United Nations and the Higher Education Sustainability Initiative (HESI)) and has raised 1.5M€+ in 2022.

We are looking for a Business Developer intern to support the development of our sales activities and deploy TASK™ within Higher Education Institutions worldwide.
