Jansen was drafted in the 2013 AFL draft by Geelong, but he didn't play a game in the two seasons he spent there. He was drafted as a strong-bodied inside midfielder with the ability to go forwards, and spent his entire time with the club playing in the VFL. He lost weight in his time at the club to help him cover the ground more easily, but he was unable to force his way into the star-studded Geelong midfield.[1]
Jansen was traded to the Brisbane Lions for the 2016 season. He played his first game in round 11 of the 2016 season against Carlton[2] and played seven games for the season, struggling for consistency.[1] He was delisted by Brisbane at the conclusion of the 2017 season after playing just eight AFL games.[3]
