Born in Luján, Buenos Aires, Mena started his career playing for Club Luján and then Club Defensores de Cambaceres, both in the third division. In 1994, he made his debuts in the Primera División with Club Atlético Platense, moving to Club Atlético Lanús for a further season.
In 1997–98, both Mena and goalkeeper Carlos Roa were bought by Spain's RCD Mallorca. Eminently a defensive-minded player, the former scored seven La Liga goals during the campaign, helping the Balearic Islands team finish fifth straight from the second level as well as to a runner-up finish in the Copa del Rey.
Subsequently, Mena signed with Atlético Madrid, where he faced stiff competition for a starting job and also suffered from injuries. He resumed his career in Spain in its second, third and fourth tiers, with a quick return to Argentina with Olimpo de Bahía Blanca in between.
Mena retired from the game in February 2005, making a return to Atlético Madrid later on, appearing for its indoor soccer side. Subsequently he began his coaching career, first with the Colchoneros' youths then acting as assistant to the C-team.
On 10 February 2014, following a division three loss at CD Sariñena which left Atlético Madrid B in the relegation zone, Mena replaced Alfredo Santaelena, who had also played for the club in the 90s, as head coach.
