[2] In late summer 2014, Vasiljević returned to Radnički Niš and remained with the club for one season.
He then joined Radnik Surdulica in the summer of 2015, making his senior debut the following spring.
In March 2018, Vasiljević extended his contract with the club for three more years,[3] and soon established himself as the team's first-choice goalkeeper.
In September 2018, Vasiljević was surprisingly called up by Mladen Krstajić to the Serbia national team to replace the injured Aleksandar Jovanović ahead of the team's UEFA Nations League games with Lithuania and Romania.
Two months later, Vasiljević received his second call-up to the team, this time replacing the injured Marko Dmitrović for Serbia's final two Nations League fixtures versus Montenegro and Lithuania.
