[citation needed] From 1991 to 1992, Yirikian worked at AUB's Jafet Library as an assistant in the Archiving and Documentation Department, and later as a computer operator at the Lebanese George Matta Establishment.

In 1993, he worked as an executive secretary of Al Maha Group Holdings in Qatar, and as an assistant management consultant at Nasser, Ghattas and Co, in Cyprus.

Under his leadership, the company achieved milestones, such as being the first to roll out 3G based on UMTS/HSPA (Universal Mobile Telecommunications System / High Speed Packet Access) technology in Armenia.

[9] In the early days of VivaCell-MTS’ operation, Yirikian not only had to overcome the technical challenges of building a radio network, installing base stations in remote areas throughout the mountainous country, recruiting specialists, but he also had to battle with the remnants of Armenian business culture from the Soviet era.

[10] The new culture of corporate management developed at VivaCell-MTS in the course of its activity gave birth to a lecture course called “Business with a Mission”, where the experience of more than 11 years of successful operation was summarized.

Ralph Yirikian has been personally lecturing for senior school children and university students, by giving them an opportunity to physically get acquainted with how the company operates, interacts with its customers and lives as a family.
