He began working at the Center of Applied Space Technology and Microgravity at the University of Bremen, where he was in charge of avionics and later management of the BremSat satellite.

Königsmann joined the sub-orbital spaceflight Blue Origin NS-37 as one of six crew members, alongside Michaela Benthaus. Benthaus contacted Königsmann to examine the possibility becoming an astronaut as a wheelchair user, which Königsmann cited as his inspiration to join the flight himself. On December 20 2025, the 10 minute flight launched from West Texas at 9:15 a.m. EST. and reached 65 miles in altitude, passing the Kármán line which is some 62 miles far away above the Earth.
