[2] Niederlechner's career is considered atypical since he became a Bundesliga player without passing through the youth ranks of a professional club.

At the age of twelve, after a single year with the club, he was forced to leave the under-13 team of 1860 Munich being deemed too small and too slow.

He moved to the local Kreisliga club TSV Ebersberg, starting playing senior football for Landesliga side FC Falke Markt Schwaben in 2008.

[7] On 28 January 2023, Niederlechner made his Hertha debut as a substitute for Wilfried Kanga, against Union Berlin.

He shares a flat with one of his best friends, Michael Vitzthum, who had been his team mate at Heidenheim, and now plays for SV Wehen Wiesbaden.
