Dundalk
Mulvenna was given a senior contract with Dundalk by manager John Gill in 2006 following a striker crisis at Oriel Park. In November 2006, Mulvenna was an unused substitute in a promotion/relegation play-off against Waterford United at the RSC. He had to wait until May 2007 to make his debut for the club when he came on as a substitute in the last five minutes against Athlone Town in a First Division match which Dundalk won 2–0 at Lissywoollenthanks to goals from Shaun Williams and Philip Hughes. His first ever career goal came at Oriel Park in September 2007 when he netted in a 4–0 win over Kilkenny City in the First Division. He made his name at the club when he scored twice in a 3–0 win over Monaghan United in the League of Ireland Cup First Round at Oriel Park in March 2008. Mulvenna was offered a full-time contract by the board of Dundalk for the 2009 season which he accepted. Then in the 2010 season he found it hard to break into the team only making seven league appearances which resulted in Mulvenna terminating his contact on 19 August 2010 citing lack of first team football as the reason behind leaving his home town club. Mulvenna signed for Shelbourne but there was a problem with his registration and found himself unable to sign for a club until June.
In June he signed for Drogheda United and made his debut on 10 June 2011 against his former club Dundalk, in Oriel Park. Drogheda won 2–1. His first goals for the club came in a 3–1 win against U.C.D on 21 June 2011.
