Sven Mislintat will leave Arsenal on 8 February, the club have confirmed.
The Premier League side’s head of recruitment has been with the Gunners since December 2017, with the club saying the 46-year-old “has done a truly outstanding job in helping us recruit players who are making a big impact now and will do so even more in the future.”
He joined from Borussia Dortmund and formed a key part of the off-field restructure overseen by then chief executive Ivan Gazidis, who has since left for Milan.
“It’s been an amazing experience to work at a great club like Arsenal in what has been a big time of change,” he told the club’s official website.
“I am excited about what the future holds for the club and am looking forward to new challenges for myself.”
It had been anticipated Mislintat would be a key figure following last May’s departure of Arsene Wenger after 22 years as boss.
He was one of three people, along with Gazidis and Raul Sanllehi, the director of football, who chose Unai Emery as Wenger’s successor.
But the upheaval of Gazidis leaving for AC Milan last September and further behind-the-scenes changes are rumoured to have led to his departure.
Arsenal added: “We wish him every success for the future and thank him for his extremely hard work on behalf of Arsenal.”
Other players to have joined Arsenal during Mislintat’s employment include Henrikh Mykhitarayan, another former Dortmund player, who moved from Manchester United in January 2018 as Alexis Sanchez went in the opposite direction.
Defender Sokratis Papastathopoulos was another arrival from Dortmund, while Lucas Torreira, Bernd Leno and Matteo Guendouzi have all become integral members of Emery’s starting XI.
Weekend reports suggested former Arsenal winger Marc Overmars could come into the club as Mislintat’s successor.
