He was head of the physics and electricity departments at the University of Florida from 1901–03 and at the University of Rochester from 1903–1904. Dorsey was assistant instructor in physics from 1904–1905, and instructor of physics from 1905–1910 at Cornell University.

From 1910–1911, Dorsey worked as an electrical engineer in the research laboratory of Western Electric Company. He worked as an inventor at the National Cash Register Company from 1912–16.
