He played for clubs such as Sturm Graz, SV Salzburg (where he claimed his first league title), Rapid Wien, Leeds United (England) and Austria Wien. Joining Leeds United in 1998, he was the first-ever Austrian outfield player (goalkeeper Alex Manninger joined Arsenal in 1997) to play in the Premier League. From 2003 he returned to Rapid Wien, winning the Austrian championship once more in 2005.
In 2006 he was announced as the new captain of Rapid (after a short period with goalkeeper Helge Payer as captain, who didn't feel comfortable in the role that was given to him after the departure of Steffen Hofmann), and in 2007, after the injuries of Andreas Ivanschitz and Martin Stranzl, he was also made captain of the national team for two matches.
He made his debut for Austria in a March 1998 friendly match against Hungary and was a participant at the 1998 FIFA World Cup but did not play. He earned 50 caps, scoring one goal. He also was part of the squad at Euro 2008.
Hiden has a UEFA B License. He was head coach of FC Pasching from 5 September 2013 to when he was appointed interim head coach of LASK Linz. His first match was a 3–1 win against Villacher SV. His final match was a 3–1 win against Union Gurten. Hiden was named interim head coach of LASK Linz after Karl Daxbacher was sacked. The club had won two of their last eight matches and lost one of their last six. In his debut on 17 March 2015, Linz and SV Horn finished in a 1–1 draw.
