The 1.95m tall Greek with quick feet is plying his trade in Bulgaria. After spending time at Aris' academies, he played in the Greek third tier with Thyella Filota in 2015. Greek giants Olympiacos held talks with Stergiakis but the goalkeeper wanted first-team football and chose to go on trial with Slavia Sofia. Stergiakis joined Bulgarian Slavia Sofia in August 2015. He became first choice goalkeeper for the U19 team and was unused substitute in 5 matches during the 2015–16 season. In the beginning of August 2016 he was on trial in the Italian Roma. He travelled to Trigoria for a trial but turned down the offer to move to the primavera squad.
On 10 April 2017, Stergiakis was officially nominated for the 2017 Golden Boy Award, becoming only the second Greek footballer to receive such a 2017 nomination alongside Lazaros Lamprou. After impressing the goalkeeping coach, Stergiakis signed a five-year contract.
In November 2018, Stergiakis was called up by Greece U21 for the first time and appeared as an unused substitute bench in the 2019 European Under-21 Championship qualification play-offs against Austria. He made his under-21 debut on 26 March 2019, in a friendly at home against Montenegro, which ended 1–1.
