On June 18, 1994, Mastalir entered the United States Air Force when he received his commission as a second lieutenant. His first assignment was as an academic processing officer at an Air Force Reserve Officer Training Corps detachment in Chicago, Illinois. He then underwent a two-month undergraduate space and missile training at the 392nd Combat Training Squadron. In September 2005, he was reassigned to the 5th Space Operations Squadron at the Onizuka Air Station, California. He spent four years there in several capacities, including as satellite procedures officer, flight director, and satellite operations instructor. He transferred to the Space Force on May 14, 2021, on the same date that the 30th Space Wing was redesignated as Space Launch Delta 30. In May 2022, he returned to Vandenberg as special assistant to Combined Force Space Component Command Commanders Major Generals DeAnna Burt and Douglas Schiess.

Mastalir played an active role in standing up Space Force component field commands. After relinquishing command of Space Launch Delta 30, he was reassigned as director of space forces of the United States Air Forces Central Command, working to standup the United States Space Forces Central (USSPACEFORCENT) in Qatar. USSPACEFORCENT was supposed to be the first Space Force component command to a geographical combatant command, but it became the next priority after the Space Force component command to the United States Indo-Pacific Command as priorities changed. On 22 November 2022, he took command of the first Space Force component field command, the United States Space Forces Indo-Pacific.

In April 2022, Mastalir was nominated for promotion to brigadier general.
