Vareille began his career in his homeland with FC Metz before moving on to FC Mulhouse. Whilst playing for Mulhouse in a pre-season friendly against Kilmarnock F.C. Vareille scored two goals, convincing then Kille boss Bobby Williamson to sign him. Vareille spent over four seasons at the club and played 113 games (with 16 goals) in all competitions whilst at Rugby Park.
Vareille joined the doomed Airdrieonians late in the 2001–02 season, which was to be their last in existence.
