Rubio made his debut for Universidad Católica in 2002 against Unión Española. After five years with Universidad Católica, Rubio left Chile at the beginning of 2007 for Mexico to play for Cruz Azul.

At the end of 2007 Rubio returned to Chile on a yearlong loan, to play for Colo-Colo where he enjoyed modest success. On July 19, 2008, it was announced he had signed for Swiss Super League Champions FC Basel on a yearlong loan. Rubio confessed that he wants to excel for the Swiss team and wants to be the best player in the league. Rubio wants to regain his striker form and score goals to come back to the Chilean National Team coached by Marcelo Bielsa. He made his Basel debut on July 23, coming on a substitute for Fabian Frei during a 1–0 win over Grasshopper Club Zürich at St. Jakob-Park. He made his full debut in a 2–0 defeat to FC Sion at Stade Tourbillon on August 2. He scored his first goal for Basel the following Week (August 9) in a 4–0 win over FC Vaduz at St. Jakob-Park. He made first European appearance in a Basel shirt on August 13, 2008 as a substitute in a 0–0 Champions League Qualifying match draw against Vitória S.C. at Estádio D. Afonso Henriques. After playing just nine games for Basel, he returned to Cruz Azul in June 2009.
