At the beginning of the 2017-18 season, German bobsleigh coach René Spies paired Buckwitz with Mariama Jamanka. The pair were nicknamed the "Berlin Bob", as Buckwitz and Jamanka are both from Berlin. Buckwitz and Jamanka won a silver medal at the 2018 Bobsleigh European Championships. At the 2018 Winter Olympics, Buckwitz and Jamanka competed in the two-woman event and won the gold medal. The win was unexpected, as the other German bobsleigh, containing Stephanie Schneider and Annika Drazek, was the favourite to win. German teams won all three of the bobsleigh events at the Games, and Buckwitz was the first person from Schöneiche to win an Olympic gold medal. As a result of her Olympic win, Buckwitz was awarded the Silbernes Lorbeerblatt (Silver Laurel Leaf), and was voted Brandenburg's Sportswoman of the Year.
