League of Ireland
O'Flynn was capped for Ireland at under-age levels. He also had spells at Cork City and Limerick when he was younger where he was very impressive at the latter. He then re signed for Cork City in 2004 and played alongside Kevin Doyle, however he was sidelined for most of the season through injury.
Following the injury, Stephen signed for Stephen Kenny's Derry City in 2005. The move reignited his career and he weighed in with several goals for Derry City including a winner against IFK Göteborg in the 2006–07 UEFA Cup in August 2006. However, when Pat Fenlon took over at Derry, he was released by the club on 14 December 2006 after 9 goals in 48 appearances.
He was signed by Galway United in preparation for their 2007 season. He was released by United in July 2008. In the same month, he returned to Limerick until the end of the 2009 season after having another injury hit season at Galway. There, O'Flynn made an impact on his return to League of Ireland football in the First Division scoring 14 goals in just 13 appearances. At the end of the 2009 season, O'Flynn made the Division One team of the year.
When he was younger, he spent a period of time at Wimbledon before he moved to Irish football. In January 2010, he held talks with English League Two Side Northampton Town, after an impressive two-week trial. On 5 January, O'Flynn signed a contract with the Cobblers until the end of the 2009–10 season. He was released by the club on 12 May 2010 along with five other players.
Return to the League of Ireland
O'Flynn returned to Limerick in the mid-season transfer window on 21 June 2010. O'Flynn spoke of his delight on returning to the club he regards as home saying, "I'm just delighted to be back. I was out of football for a year with injury when Pat Scully gave me a chance last year. I did well enough to earn a contract in England. Some of the players here were inexperienced last year but have come a long way in the last 12 months, I've been around a few years now and the set up here, on and off the pitch is absolutely top-class, Pat O'Sullivan can take a lot of credit for that, what he's doing for soccer in Limerick is unbelievable. We're 16 years stuck in this Division and it's time we got back where we belong, rugby and Gaelic have taken over in terms of support in Limerick and it's time we changed that.
St Patrick's Athletic
O'Flynn announced on his Twitter account that he had signed for Premier Division side St.Patrick's Athletic, in January 2012. O'Flynn started off life at the Inchicore club, scoring on his first start away to Dundalk in a 2–0 win.
