A former discus and hammer thrower of Berlin, Jamanka became a bobsledder in 2013. She entered the Bobsleigh World Cup during the 2015–16 season. In January 2017 she won the European Championship in Winterberg with brakewoman Annika Drazek. Later the same year she was part of the gold-winning German team in the mixed team event at the IBSF World Championships in Königssee.
Before the 2018 Winter Olympics in Pyeongchang, Germany's head coach René Spies changed the brakewomen of the country's two leading two-women bobsleighs: Drazek was assigned to pilot Stephanie Schneider, while Jamanka had to work with Schneider's former brakewoman Lisa Buckwitz, with Schneider and Drazek being the most aspiring German team for the Pyeongchang Games. However, Jamanka and Buckwitz won the event, winning Germany's first two-woman bobsleigh medal since 2006, while Schneider and Drazek, who both became injured during the Games, finished fourth.
