He was ordained to the priesthood by Cardinal George Mundelein on April 2, 1932. He then served as a curate at St. Aloysius Church until 1935, when he became a member of the Archdiocesan Mission Band. He was later rector of Angel Guardian Orphanage (1950–1953).

On November 3, 1953, Hillinger was appointed the fourth Bishop of Rockford by Pope Pius XII. He received his episcopal consecration on the following December 29 from Cardinal Samuel Stritch, with Bishops Martin Dewey McNamara and William Aloysius O'Connor serving as co-consecrators. He was installed at St. James Pro-Cathedral on January 14, 1954. Hillinger remained at Rockford for two years, when he was named Auxiliary Bishop of Chicago and Titular Bishop of Derbe on June 27, 1956. He confirmed Peoria's Bishop Daniel R. Jenky, C.S.C., and ordained the late Francis Cardinal George, O.M.I., of Chicago, to the priesthood.
