Rubensson started playing football at Marieholms IS. From 2010 she played for
Malmö FF in the
Damallsvenskan, with which she became champion in 2010, 2011, 2013, and 2014 and won the 2012 Supercup. She also took the team to the
Champions League four times, with the best showing being reaching the quarter-finals in
2011/12 and
2012/13. In May 2013 Malmö converted Rubensson from a
forward to a
left back. She left champions Malmö (who had become known as FC Rosengård) in December 2014, to sign a two-year contract with
Kopparbergs/Göteborg FC. They finished second in the
2018 season, meaning the team qualified for the
2019–20 Champions League. After a 1–2 home defeat against
Bayern Munich, in which she scored the goal for her team, they won 1–0 in Munich, but the away goals rule was against the Swedes. On 4 August 2018 she signed a 5-year contract extension with Kopparbergs/Göteborg FC. On 1 May 2019 she won the cup with Kopparbergs/Göteborg FC, scoring the 2–1 winning goal from a penalty in the first minute of stoppage time. On 29 September 2019 she suffered a head injury during the league game against
Vittsjö GIK. She played at the start of the 2021 season, also due to the subsequent pregnancy and parental leave. By then she was a regular player again at the club, which is now named BK Häcken. In the
2021–22 Champions League, she reached the group stage for the first time after two wins in the qualifying final against
Vålerenga Oslo. Here they won the away game against
Benfica Lisbon 1–0. The other games were lost, so they were eliminated as bottom of the group. Rubensson played in all games and also scored the goal for her team from a penalty in the 1–2 home defeat against Benfica. She and her club failed to qualify for the group stage of the
2022–23 Champions League against
Paris Saint-Germain. In 2024, Rubensson signed with the
Houston Dash in the
NWSL. The club announced her departure on 6 December 2024. ==International career==
