In the same year, he returned to Belgrade at the municipality's invitation to establish a chemical laboratory. Due to material reasons, the Belgrade municipality could not establish a laboratory, so Zega worked as a municipal chemist in the State Chemical Laboratory from 1891 to 1906. In 1894, Zega applied for the position of professor of chemistry and chemical technology at the 185:, but also well water. After his release, he worked in the Municipal Chemical Laboratory until 1922, and then transferred to the Customs Laboratory, where he worked until 1925. In November 1926, he retired but was also transferred to the civil service as the head of the chemical laboratory within the Sava Customs House. In March 1927, he became seriously ill and retired.
