Sosa played for Estudiantes between 2002 and 2007. He was a favorite of interim coach Carlos Bilardo, and together with Marcelo Carrusca started helping the team improve their standing in the Argentine league. The highlight of his tenure with Estudiantes was being a key piece in the 7–0 defeat of derby rivals Gimnasia on 15 October 2006, and then his role in helping the team win their first league title since 1983 by scoring the equalizing goal from a free kick against Boca Juniors in the 2006 Apertura final playoff game.
On 24 February 2007, a deal was announced between Estudiantes and Bayern Munich, in which Sosa would be transferred to Bayern Munich for an undisclosed fee. Sosa stayed with Estudiantes for the remainder of the Clausura 2007 tournament.
On 29 October 2009, Bayern Munich announced that the Argentine midfielder will be loaned to his former club Estudiantes for the remainder of the season, even though he was not registered to play the 2009 World Club Championship finals.
On 26 July 2011, it was announced that Jose Sosa had joined the Ukrainian team Metalist Kharkiv for €1.9 million. For his tenure with Metalist, Sosa adopted the number 11 jersey honoring his admired ex-teammate Juan Sebastián Verón, and has been instrumental in the team's successful Europa League campaign. On 28 June 2012, Sosa was named as the new captain of FC Metalist Kharkiv.
On 1 January 2014, it was announced that he will join Atlético Madrid on six-month loan. With the Spaniards, he won the Spanish Liga and played in the 2014 UEFA Champions League Final against Real Madrid, coming on as a substitute, as Atlético lost 4–1 after extra time.
On 31 August 2014, Sosa was signed by Turkish club Beşiktaş on loan from Metalist Kharkiv. On 15 October 2014, the club announced that the buying option has been used, making Sosa's move to the Turkish side definitive, for €3.4 million. In the 2015–16 season, Sosa served 12 assists in 2015–16 Süper Lig, at least 4 more than any other player.
On 17 August 2016, Sosa joined Italian club A.C. Milan for €7.5 million fee, signing a two-year deal. He made his debut for Milan on 27 August 2016, coming off the bench in the 80th minute during a 4-2 loss away against his former club Napoli.
National coach Alfio Basile drafted Sosa for the senior national team on 28 February 2007. Sosa said to the press that he will "never forget this Tuesday" in which he achieved two of his childhood dreams (the transfer to a major European club and the call to the national team).
He made his debut as a substitute at a friendly match against Mexico on 9 March 2007. He started his first match against Chile, on 18 April 2007. His first goal with the Albiceleste arrived on 23 January 2010, in a 3–2 win in a friendly match against Costa Rica, scoring the opening goal of the game with a header on 10 minutes.
Sosa was not called to the World Cup 2010 team by then-manager Diego Maradona, but was reinstated by new coach Alejandro Sabella for the World Cup 2014 qualifiers, and has been featured in several games since 2011.
