He was selected to officiate the final of the 2011 FIFA U-17 World Cup on 10 July 2011.

Moen was in charge of the UEFA Champions League quarter final between Bayern Munich and Olympique de Marseille in 2012. He was also in charge of UEFA Champions League second round first leg between Bayern Munich and Arsenal on 19 February 2013 at the Emirates Stadium where he controversially awarded a corner to Arsenal that led to Arsenal's only goal.

He officiated in the Euro 2016 qualifier Germany v Scotland on 7 September 2014.
