[2] By AD 213, he was the Comes in expeditione Germanica (or head of the expedition against the Germanic tribes) before being appointed for a three-month stint as imperial legate of the province of Raetia, serving from October to December 213.
An amicus (or intimate friend) of the emperor Caracalla, Suetrius Sabinus was appointed consul ordinarius alongside Lucius Valerius Messalla Apollinaris in AD 214.
[3] After his consulship, Caracalla appointed Suetrius Sabinus as a iudex (judge representing the emperor) in an unknown province, followed by a period as praefectus alimentorum (or the officer in charge of Rome's food supply).
This was an exceptional appointment in terms of its function; it may be that his principal task was to deal with a breakdown of law and order in Italy during that time, with a rise in banditry afflicting the countryside.
X. Loriat believes it is a reasonable conjecture that Suetris Sabinus played a role in the elevation of the young Gordian III in June 238, for he was appointed consul ordinarius a second time in 240, alongside Lucius Ragonius Venustus, an honor not bestowed on a private citizen since Gaius Bruttius Praesens in 153 and 180, and on few afterwards.
