Former Czech Republic international Pavel Hapal had previously been in charge, but he was sacked after a shock defeat at home to Israel in the Nations League.
As soon as he was in post, Tarkovic’s immediate task was to secure qualification for the Euros by beating Ian Baraclough’s side in a one-off game at Windsor Park.
Slovakia took the lead thanks to Juraj Kucka, but Northern Ireland struck back through a Milan Skriniar own goal late on, taking the match to extra time.
Substitute Michal Duris notched the winner with 10 minutes remaining, firing past Bailey Peacock-Farrell to break the home team’s hearts.
The 48-year-old has previously worked as part of his country’s youth set-up and acted as assistant manager to Jan Kozak, briefly taking on the top job in a caretaker capacity in October 2018.
In club football, Tarkovic has previously managed MFK Kosice, Tatran Presov and MSK Zilina, each for short periods of time.
This is just Slovakia’s second appearance at a European Championship, having reached the round of 16 in France five years ago.
Several of that squad will be involved again this summer, including captain and talismanic midfielder Marek Hamsik, who spent 12 years at Napoli.
