In 2014 Geferson was promoted to the main squad, but made no official appearances over the year. After the arrival of new coach Diego Aguirre, he was named as a backup to Fabrício, and made his debut as a senior on 14 February 2015, starting in a 2–1 away win against Caxias, for that year's Campeonato Gaúcho.
After Fabrício's loan to Cruzeiro, Geferson was made a starter by Aguirre, and appeared in nine matches during the tournament. On 23 May 2015 he made his Série A debut, playing the full 90 minutes in a 1–1 away draw against Vasco da Gama.
After representing Brazil in the under-17 level, Geferson was called up to the main squad on 29 May 2015 for the year's Copa América, as a replacement for the injured Marcelo, but Filipe Luís occupied Brazil's starting left-back position as they reached the quarter-finals.
