As a professional, he appeared rarely over the course of two seasons, all the matches being played in 1994–95, his debut coming on 1 April 1995 in a 1–3 away loss against TSV 1860 München, as the team ended a four-stay in the Bundesliga.

In 1995, Jeremies signed for 1860 Munich, helping the Lions qualify for the UEFA Cup in his second year and receiving totals of 30 yellow cards and two red during his three-year spell.

[4] Whilst at TSV Munich, Jeremies made his debut for the Germany national team on 15 November 1997 in a friendly against South Africa, playing the full 90 minutes in a 3–0 win in Düsseldorf.

He was then picked for the squad at the 1998 FIFA World Cup, appearing in three games in an eventual last-eight exit; during the competition, German entertainer Harald Schmidt reverentially called him "Jens Jerenaldo".

[6] Jeremies was reinstated for the 2002 World Cup,[7] even captaining the team once in a friendly after the competition,[8] but retired from international football after Germany's group stage exit in Euro 2004 in Portugal, saying he wanted to focus on his club duties with Bayern.
