Einarson won her first provincial mixed title in 2010, playing third for Dave Boehmer. The team represented Manitoba at the 2010 Canadian Mixed Curling Championship, where they lost in the tiebreaker match. At the 2013 provincial mixed (played in 2012), Einarson played third for Terry McNamee and won her second provincial mixed title. This team played in the 2013 Canadian Mixed Curling Championship, finishing with a 4–7 record.

Einarson has skipped her own team on the women's World Curling Tour since 2008, except for one season playing third for Jill Thurston in the 2011–12 season.^[3] The following season, she finished second at the 2012 Atkins Curling Supplies Women's Classic.

Einarson scored a rare eight-ender in her first round robin game of the 2015 Manitoba Scotties Tournament of Hearts against Tiffany McLean. It was the first time a team scored an eight-ender in recorded Manitoba Scotties history.^[4]

Einarson's first Tour event win as a skip was at the 2015 GSOC Tour Challenge, where she finished first in the tier 2 event and won a spot at the 2015 The Masters Grand Slam of Curling where she would lose to Val Sweeting in the semifinals. Einarson would make it to two more semifinals at Grand Slams that season. That year Einarson would also win her first provincial championship, qualifying her team of Selena Kaatz, Liz Fyfe and Kristin MacCuish to represent Manitoba at the 2016 Scotties Tournament of Hearts. There, she led her province to a 7–4 round robin record, qualifying the team to the playoffs. In the playoffs however, she would go on to lose both games, settling for fourth place.

The next season, Einarson won her first Grand Slam event, the 2016 Boost National. Her next tour event win was at the 2017 Icebreaker at The Granite. Two weeks later she won the 2017 GSOC Tour Challenge Tier 2 event. While she didn't win any more events that season, she made it to the finals in two Grand Slams, losing to Jennifer Jones at the 2017 Masters of Curling and to Rachel Homan at the 2018 Humpty's Champions Cup. Einarson's team had a disappointing showing at the 2017 Canadian Olympic Curling Pre-Trials, where she lost in a tiebreaker. However, her team amassed enough tour points over the season to play in the first ever Scotties Tournament of Hearts wildcard game against the higher ranked Chelsea Carey rink. Einarson beat Carey for the right to represent the new "Team Wildcard" at the 2018 Scotties Tournament of Hearts. There, she went on a roll, going 9–2 in round robin pool, to finish in a three-way tie for first. In the playoffs she lost to Jennifer Jones' team Manitoba in the 1 vs. 2 game, beat Nova Scotia in the semifinal, and then lost to Jones again in the final. Despite a successful season, the Einarson team would split up.

For the 2018–19 season, Einarson would form a new team of Val Sweeting, Shannon Birchard and Briane Meilleur, all former skips.^[5] They began the season by winning four straight World Curling Tour events in three weeks: the 2018 Stu Sells Oakville Tankard, the inaugural Morris SunSpiel, and the Mother Club Fall Curling Classic,^[6] and in October they won the Curlers Corner Autumn Gold Classic.^[5] In December, the team lost in the finals of the 2018 Canada Cup and 2018 National. Their strong play during the early part of the season earned them enough points to put Einarson in the Wild Card game once again at the 2019 Scotties Tournament of Hearts. However this time, she was not successful, losing to the lower ranked Casey Scheidegger rink. The team would rebound to have a strong finish at the end of the season, winning the 2019 Players' Championship and losing in the final of the 2019 Champions Cup.

Team Einarson had two playoff finishes at the first two Slams of the 2019–20 season, losing to Anna Hasselborg in the quarterfinal of the Masters and once again to Hasselborg in the final of the Tour Challenge. The team did not have the same success at the Canada Cup as they did in 2018, finishing with a 2–4 record. However, at the 2020 Manitoba Scotties Tournament of Hearts, her team succeeded. They finished the round robin and championship round with a 7–1 record which qualified them for the final. In the final, Einarson defeated Jennifer Jones to win her second Manitoba Scotties Tournament of Hearts. Team Einarson represented Manitoba at the 2020 Scotties Tournament of Hearts, where they continued their success. They finished first in the round robin with a 9–2 record and then won the 1 vs. 2 page playoff game, qualifying them for the final. Einarson would win her first Canadian Championship with a draw to the button for an 8–7 win against Rachel Homan.^[7] For her strong play through the week of the Scotties she was named the MVP of the tournament and was awarded the second team all-star as skip.^[8] The team was set to represent Canada at the 2020 World Women's Curling Championship before the event got cancelled due to the COVID-19 pandemic.^[9][10] The Scotties would be their last event of the season as both the Players' Championship and the Champions Cup Grand Slam events were also cancelled due to the pandemic.^[11]

Team Einarson returned to the Scotties Tournament of Hearts in 2021 as Team Canada, played in a "curling bubble" in Calgary, with no spectators, to avoid the spread of the coronavirus. They went 7–1 in the round robin, with their only loss coming against Ontario's Rachel Homan. This qualified them for the championship round. There, they won three games and lost one to Manitoba's Jennifer Jones.^[12] They advanced to the playoffs as the second seed, defeating Alberta's Laura Walker 9–3 in the semifinal. In the final, they defeated Homan to win their second consecutive Scotties gold.^[13] Einarson was named to the First Team All-Stars for the tournament, alongside teammates Shannon Birchard and Val Sweeting.^[14] A month later, and Einarson was back in the Calgary bubble to team up with Brad Gushue at the 2021 Canadian Mixed Doubles Curling Championship. It was her first time playing mixed doubles curling. After finishing pool play with a 5–1 record, the pair won five of six of their playoff matches, including the championship game against Kadriana Sahaidak and Colton Lott.^[15] Einarson returned to the bubble for a third time in April 2021, along with her women's team to play in the two only Grand Slam events of the abbreviated season.

There, the pair had a strong showing, finishing the round robin with a 7–2 record.^[20] They then faced Switzerland in the qualification game which they won by stealing the extra end, thanks to a near impossible shot made by Einarson in the eighth end.^[21] They then lost to Scotland in the semifinal and Sweden in the bronze medal game, settling for fourth place.^[22]

The Einarson rink had a slow start to the 2021–22 season, failing to win any of their first five tour events. Their best finish came at the 2021 Sherwood Park Women's Curling Classic where they lost in the final to Tracy Fleury.^[23] The team reached the quarterfinals of the 2021 Masters, however, then missed the playoffs at the 2021 National. At the 2021 Canadian Olympic Curling Trials, the team went through the round robin with a 4–4 record. This earned them a spot in the first tiebreaker, where they defeated Casey Scheidegger 8–6. They then faced Krista McCarville in the second tiebreaker, where they lost 4–3 and were eliminated.^[24] The team's next event was the 2022 Scotties Tournament of Hearts in Thunder Bay, Ontario. Through the round robin, the defending Scotties champions posted a perfect 8–0 record, earning a spot in the playoffs. They then lost in the seeding round to New Brunswick's Andrea Crawford, meaning they would have to win three straight games to defend their championship title. In the playoffs, the team won the 3 vs. 4 page playoff against Team Fleury and then defeated New Brunswick's Crawford in the semifinal to reach the Scotties final where they would face Northern Ontario's McCarville rink. After controlling the entire game, Team Einarson sealed the victory with a steal of one in the tenth end.^[25] With the win, they became just the fourth team to win three consecutive Scotties titles. They then went on to represent Canada at the 2022 World Women's Curling Championship, where they fared much better than in 2021. The team finished the round robin tied for second place with a 9–3 record, however, due to their draw shot challenge, finished third overall. This placed them in the qualification game where they defeated Denmark's Madeleine Dupont to advance to the semifinal. There, they took on South Korea's Kim Eun-jung. After taking control in the seventh end, South Korea stole the ninth and tenth ends to hand the Canadian team a 9–6 loss.^[26] They were able to rebound in the bronze medal game with an 8–7 victory over Sweden's Anna Hasselborg.^[27] Team Einarson wrapped up their season at the final two Slams of the season.

After trading singles, Team Canada stole two in the fifth end to open a two-point lead. They secured their record tying fourth Scotties title with a score of five in the ninth end.^[39] The team then advanced to the 2023 World Women's Curling Championship where they reached the playoffs again with a 7–5 record.^[40] After defeating Japan in the qualification game, they lost in the semifinals for a second year in a row, 8–5 to Norway.^[41] They won another bronze medal after an 8–5 win over Sweden.^[42] Team Einarson reached the semifinals of the 2023 Players' Championship where they fell 10–3 to Isabella Wranå.^[43] They finished their season at the 2023 Champions Cup where they lost 6–5 to Team Homan in the championship game.^[44]

The team did not have a great week, however, losing both the semifinal and bronze medal game to finish fourth.^[46] In Grand Slam play, Team Einarson failed to reach any finals for the first time since forming. They had three semifinal finishes and one quarterfinal appearance before missing the playoffs at the 2024 Players' Championship, breaking their streak of qualifying at the previous twelve Slams. A few hours prior to the first draw of the 2024 Scotties Tournament of Hearts, Curling Canada announced that the team's lead Briane Harris was deemed "ineligible" to play in the tournament without going into any more detail. She was replaced by alternate Krysten Karwacki.^[47] Despite the disturbance, Team Einarson managed a 7–1 record through the round robin to qualify for the championship round. Once there, however, they lost both their games to Team Homan and Manitoba's Kate Cameron, eliminating them from contention and ending their chance of a record setting fifth straight Scotties title.^[48] Following the event, in March, it was revealed that Harris had been provisionally suspended for up to four years for testing positive for Ligandrol, a banned substance. She will be appealing the decision to the Court of Arbitration for Sport.^[49] Harris was also replaced by Karwacki for the Players' Championship at the end of the season.
