Born in Vic, Barcelona, Catalonia, Riera played youth football with La Liga giants FC Barcelona, but spent the vast majority of his tenure with the club in representation of the C and B-teams. His official input with the main squad consisted of 13 minutes in a 4–0 away win against Ciudad de Murcia for the season's Copa del Rey – when he was still a junior – on 17 December 2003.
After leaving the Camp Nou, Riera resumed his career in Segunda División B, where he played with Cultural y Deportiva Leonesa and Celta de Vigo B. He appeared in five Segunda División games with the latter's main squad, four as a starter.
From 2009 to 2013, Riera competed in the second level, with Córdoba CF and AD Alcorcón. He scored 18 goals in his second year with the latter side, (including a hat-trick in a 3–1 success at UD Las Palmas on 8 September 2012), helping them to the promotion play-offs.
On 5 July 2013, Riera signed for three seasons with CA Osasuna. He made his La Liga debut on 18 August, coming on as a second-half substitute in a 1–2 home loss to Granada CF; his first goal in the competition came on 20 September of the same year, in a 2–1 win against Elche CF also at the El Sadar Stadium.
On 28 June 2014, after Osasuna's relegation, Riera agreed to a three-year deal with Wigan Athletic of the Football League Championship, for a reported £2 million fee. He scored his first goal for his new team on 23 August, the only against Blackpool in a 1–0 victory at the DW Stadium.
Riera returned to his country's top division on 7 January 2015, signing on loan to Deportivo de La Coruña until the end of the season. On 30 June he agreed to a permanent deal at the Estadio Riazor, having narrowly avoided relegation.
On 12 August 2016, Riera returned to his former club Osasuna after agreeing to a one-year loan deal.
