Cross country was her focus after the track season. She won the Cross de l'Acier in France in November 2014. She was chosen for the senior Ethiopian team for the 2015 IAAF World Cross Country Championships and, in spite of her suffering an injury in the week before the event, she took to the front pack alongside Agnes Jebet Tirop and the two became the race protagonists, with Tirop eventually beating Senbere in the final 200 m, leaving the Ethiopian with the silver medal. Senbere's senior debut also saw her head the Ethiopian women to the team title, helped by her compatriot (and bronze medallist) Netsanet Gudeta.
