On October 16, 1977, Jan Goossens made his debut on the first squad of NEC Nijmegen in a home match against FC Twente.
In the beginning of 1979 Jan Goossens transferred from NEC to the Edmonton Drillers of the North American Soccer League, where Hans Kraay Sr. was the head coach at that time.
In 1982 the Edmonton Drillers folded due to financial troubles, which caused Goossens to leave for a club from the United States of America.
Jan Goossens left the Golden Bay Earthquakes in 1984 for the Minnesota Strikers, but due to his knee injury he was not able to play any match the first season.
The Minnesota Strikers ended the 1985-1986 MISL season as runner up, after losing the playoff final against the San Diego Sockers (4-3).
In 1986 Jan Goossens left the Minnesota Strikers and moved to the Kansas City Comets, where he would play until that team folded in 1991.
Goossens played three MISL playoff finals with the Kansas City Comets, but the team ended up as runner-up every time.
