As an alternate for Team Edin during this period, Eriksson received numerous international medals, including two gold medals at the European Curling Championships (2009 and 2012) and three World Curling Championship medals, including his first World Championship gold medal (2013) and two bronze medals (2011 and 2012). He played his first full games at a major championship in the senior division at the 2011 European Curling Championships in the final two round-robin draws. At the 2012 World Men's Curling Championship, however, he notably played in the second position for all games except three because Niklas Edin, the permanent skip, was suffering from a herniated disc in his back. Eriksson also played this position in the playoffs, in which Team Sweden won its second World Curling Championship bronze medal. At the 2013 European Curling Championships, he also curled for a third of the round-robin games, playing the second position in the seventh and eighth draws and the third position in the final draw, helping the team secure a winning record, despite not making the playoffs. He also made his first Olympic appearances with Team Edin, coming in fourth in the 2010 Winter Olympics and receiving a bronze medal in the 2014 Winter Olympics.
