Landsem replaced Bjarne Berntsen as national team coach in October 2009. She qualified the team for the 2011 FIFA Women's World Cup in Germany, but Norway crashed out in the first round. Results did not improve and a review carried out by Football Association of Norway's (NFF) Nils Johan Semb revealed that some players were unhappy with Landsem.[4] Her contract was not renewed beyond 31 December 2012 and veteran Even Pellerud returned to the role.
From November 2014 to March 2015 she managed another men's team, Fjellhamar FK, but resigned due to lack of available players.[5] Ahead of the 2018 season she was named director of sports of Vålerenga Fotball Damer.[6]
