Jan Siewert

Coaching career Early career Siewert trained at the Hennes-Weisweiler-Akademie. He was sacked by the club in April 2016 after the club entered the relegation zone. Siewert then became assistant manager of VfL Bochum, manager of the VfL Bochum under-19 team, and manager of Borussia Dortmund II.

Huddersfield Town In January 2019, he was linked with the vacant manager's position at Premier League club Huddersfield Town, and later that month he was appointed to the role, signing a contract until the summer of 2021. In doing so, he became the third Borussia Dortmund II manager in a row to leave that role to work in England; after David Wagner (who he replaced at Huddersfield) and Daniel Farke (who became manager of Norwich City). Siewert stated that he did not wish to be compared to Wagner, his predecessor at Huddersfield. Huddersfield were relegated to The Championship in March 2019 with six games remaining, joining Ipswich Town and Derby County as being the only Premier League teams to have been relegated so early in the season. Huddersfield gained one point from their first three league games in the 2019–20 season and were knocked out of the EFL Cup first round by Lincoln City and on 16 August 2019, after one win during 19 games in charge, Siewert was sacked. He later said that he "left his heart" at Huddersfield.

Return to Germany On 1 July 2020 he became the Academy Manager at Mainz 05. On 28 December 2020, Siewert was appointed as interim manager of Mainz's first team in the Bundesliga after Jan-Moritz Lichte was dismissed. He managed one game before being replaced by Bo Svensson.

On 2 November 2023, he became interim manager once again, replacing Svensson until further notice. On 22 December 2023, Mainz announced that Siewert had been made permanent manager of the club. He was sacked on 12 February 2024 after just one win in twelve matches.

In November 2024, he was named the new head coach of Greuther Fürth. In May 2025, he was sacked.

Personal life As of January 2020 Siewert was married with a three-year-old son.
