In 2024, Eriksson and Niklas Edin became the first and only two curlers in history to have seven career gold World Men's Curling Championship medals.

At those three World Junior Championships, Eriksson skipped two different Swedish teams, winning a total of 24 games and losing only 9.

[19] 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.

[22] When Lindström underwent surgery in 2016 and needed recovery, however, Rasmus Wranå began curling in the second position for the team.

Since the 2014-15 season, Eriksson and his teammates have consistently ranked in the top ten teams in the world since they joined forces due to their performance in Canada and worldwide.

Indeed, in the 2016-17 season, Team Edin had their most successful year on tour, winning three Slams (the Masters, the Tour Challenge, and the Players’ Championship) and reaching the finals (the Canadian Open) and semifinals (the National and Champions Cup) of all but one of the slams, securing the Pinty’s Cup, the first non-Canadian men's team to do so.

In mixed curling, his most successful run at the Swedish national championships occurred in 2008, where his team – consisting of Christoffer Sundgren, Maria Östman, and Marina Stener – reached second place, losing to the team of Niklas Edin, Anette Norberg, Eric Carlsén, and Anna Hasselborg.

[24] His last appearance in the Swedish national mixed championships was in 2012 when he curled with Hasselborg, Kristian Lindström, and Marina Stener.

Eriksson's longest-running mixed doubles partnership is with Anna Hasselborg, with whom he began curling at Härnosands gymnasium.

Eriksson was selected for one of the teams, partnering with Almida de Val, as Hasselborg chose not to participate in mixed doubles during the 2020-21 curling season.

[34][35] Eriksson and de Val were undefeated in the preliminary rounds and after a tight loss in the semifinal won the bronze medal, defeating Kerri Einarson an Brad Gushue.

[36] At the conclusion of the season, Eriksson and de Val were chosen to represent Team Sweden in mixed doubles at the 2022 Winter Olympics.

[38] In December 2021, Eriksson and de Val competed in the Gothenburg Mixed Doubles Cup and finished first in the overall standings heading into the playoffs, ultimately winning the silver medal in the tournament.

[39] In preparation for the Winter Olympics, De Val and Eriksson had completed an intense training season under controlled conditions, but when one of their coaches tested positive for COVID-19, their arrival in Beijing was delayed until the day before the competition.

[40] After an extremely competitive round-robin program, Eriksson and De Val finished in fourth place, losing in the semifinals to Italy but defeating Great Britain to secure the bronze medal.

Currently, Eriksson is the only Swedish curler to have taken part in fourteen consecutive World Curling Championships in the men's division (2011-2024, with no such event held in 2020).

Eriksson has also competed in thirteen consecutive European Curling Championships, winning seven gold medals, a record that he shares only with Niklas Edin.

Eriksson and Edin had previously become the first men's curlers to simultaneously hold those same titles in three separate competition seasons (2012-2013, 2014–2015, and 2017-2018).
