From 1835 to 1840 he trained as a teacher in Freiberg, after which he worked as an elementary teacher in Elterlein and, from 1846, as a community school teacher in Chemnitz . In 1850 he became a teacher of pure mathematics, mechanics and practical geometry at the royal trade school in Chemnitz . In 1855 Junge received his doctorate from the University of Leipzig . In the same year he became a professor of mathematics at the Bergakademie Freiberg . He initially held lectures on higher mathematics and geometry as well as higher analysis. From 1856 he also read about descriptive geometry and from 1859 about practical marquetry, and in 1860 probability calculations were added.

Young's merits were the mathematization of the art of marrow sheath and the improvement and construction of marrow sheath instruments.
