Jenni made his professional debuts in 1993-94 when he left Grasshoper-Club that had formed him to sign with HC Lugano of the NLA. He became a hit the following season, pcking up 38 points in 36 games. Jenni had a successful stay in Lugano, being crowned Swiss Champion with the team in 1999 when Lugano defeated neighbour and rival HC Ambri-Piotta in the NLA playoffs finals. He was part of a devastating line with Patrick Fischer and Gian-Marco Crameri not only in Lugano, but also on the Swiss National Team, for which Jenni played 53 games in international tournaments for the senior squad and 25 with the junior.
In 2000, Jenni leaves his homeland, heading for Sweden and the Elitserien, having been hired by Färjestads BK. The signing paid off for Färjestad; Jenni was the playoffs' top scorer in 2001, and the next year, he helped them become Swedish Champions.
Jenni left the club in 2005, returning to Switzerland with Kloten.
