Northern Ireland national youth coach Stephen Frail has taken up the assistant manager post at Dundee United.
Frail had held the post of manager for the Northern Ireland under-17 and under-19 teams for four-and-a-half years.
Northern Ireland manager Ian Baraclough told the Irish FA: "I'm delighted for Stephen to get this opportunity.
"He has been a real asset for the development of our underage groups and the association as a whole.
"He joined on my first trip as the U21s manager to Estonia and was a huge help to me during that period.
"He has been an asset from day one and we wish him every success in this new and exciting role."
