Friedrich was the son of Johann Jakob Hiller, pastor at Mühlhausen.
He was educated at clergy training schools at Denkendorf (under J. A. Bengel) and Maulbronn, and at the University of Tübingen (MA 1720).
His first clerical post was assistant at Brettach (now Langenbrettach) (1724–27). He later held similar posts at Hessigheim and elsewhere, and from 1729–31 was a private tutor at Nuremberg.
On St. Bartholomew’s Day, 1732, he became pastor of Neckargröningen. In 1736 he became pastor of his hometown, and in 1748 pastor of Steinheim (near Heidenheim).
In his third year at Steinheim, he lost his voice, and had to use an assistant to preach.
