Mario Jobst is one of the most important contemporary architects in Serbia.

Born in Belgrade in 1940, Jobst graduated from he Belgrade Faculty of Architecture in 1971 and consequently started his career as design architect in the largest architectural company in Serbia, „Energoprojekt“, advancing gradually from the position of design consultant to department director.

Early influences include time in the office of the famous Slovene architect Edo Ravnikar, as well as a year in Frankfurt am Mein (Germany), in "Filip Holzman" studio, under the supervision of Ing. Kirchner. The years of studying were marked by the then current processes particular to Yugoslav architectural scene, the main characteristics of which might be said to have been the influence of Milan Zlokovic and especially his engagement with some of the Corbusian principles of modular design, which can be traced in Jobst's design practice. 

First employed in 1972 as part of the new generation of young, promising architects under the supervision of Milica Sterić, succeeded in winning an important competition the following year (together with Miloš and Slavka Stanković, Zorica Sikimić & Olivera Radović), which proposed an interesting solution for a sports centre in the Serbian town of Zaječar. 

The character of „Energoprojekt“ and its policies inevitably dictated the range of projects Jobst was getting involved with, and many of these comprised projects monumental in size and scope. These project were characterised by strong geometric forms and the emphatic use of red steel.
