While in the United States, Jordan began his medical practice and also opened a school for midwives. After returning to Europe, he continued to work first in England, then in Germany. Back in Kraków, Jordan took on a number of social functions. From 1895 to 1901 he was a Member of Parliament representing the city at the Polish Diet of Galicia and Lodomeria. In addition, Jordan presided over the Kraków Gynecological Society, as well as the Society of Medical Doctors, and the Association of Polish Teachers of Higher Education (a precursor to Polish Teachers' Union). Thanks to his efforts, physical education classes were introduced as compulsory into all Polish schools.
