Republic of Ireland women's team manager Colin Bell is leaving to become assistant manager of Huddersfield Town.
Bell, who has managed Ireland since February 2017, has been been appointed assistant to manager Jan Siewert at the recently relegated club.
Bell will commence work at the Championship side immediately.
Current women's U17 and U19 head coach Dave Connell is expected to be among the frontrunners to replace the Englishman.
Connell, who is also the FAI's Head of Women's Underage Development, led the U19s to the semi-finals of the European Championships in 2014.
FAI High Performance Director Ruud Dokter paid tribute to Bell's work with the Irish squad over the last two years.
He said: "Colin has done a fantastic job in his time with Ireland and I want to thank him for that. He has introduced new players to international football and brought our team to a new place.
"The World Cup qualifying campaign saw him bed in his ideas very quickly and the players responded with high level performances.
"His passion, commitment and desire to develop women’s football in Ireland was exemplary and I wish him well at Huddersfield. The challenge now for the new management and the players is to qualify for the European Championships."
Taking over as Ireland women's team manager in the midst of the players' strike in early 2017, Bell led the team to third place in a difficult World Cup qualifying group behind Norway and Netherlands.
He leaves the position nine weeks out from the start of Ireland's Euro 2021 qualifier opener at home to Montenegro.
