Former Dungannon Swifts manager Darren Murphy is back at Linfield as part of David Healy's backroom team.
The IFA Elite Performance Coach, who was a Blues defender for four years, resigned as Swifts boss in 2015.
Murphy, 43, was linked with the vacant manager post at Glentoran but his future lies at Windsor Park.
"Darren will take up a position within manager David Healy's backroom staff from 1 June and we wish him every success in this role," said the club.
Murphy also played for Portadown, Glenavon, Dungannon and Ballymena before taking over the Swifts hotseat in 2012.
He helped the Tyrone club to three consecutive Mid-Ulster Cup titles during his spell in charge at Stangmore Park.
"I know Darren well and he's an experienced coach who knows the league well and he will bring considerable enthusiasm to his new role," said Healy.
"He did an excellent job at Dungannon Swifts during his time there and I know he learned a lot from that experience and I'm sure he will be a most welcome addition to our coaching and backroom staff.
"He's looking forward to getting started in his new role and he's a popular person who I know our supporters will welcome back to the club where he gave total commitment during his playing career."
Linfield finished fourth in the Premiership last season and failed to qualify for European football for the first time in 15 years.
