Ulster have announced that their head coach Mark Anscombe is to leave the Ravenhill-based province with immediate effect.
The news comes just weeks after Ulster's director of rugby David Humphreys announced that he was leaving to further his career with Gloucester.
Les Kiss will take-up the position of interim director of rugby to allow time for a review of the coaching structures at Ulster to take place.
Kiss will continue as Ireland Assistant Coach and will combine his duties with the international side with his new role at Ulster.
Ulster Rugby Chief Executive, Shane Logan, said: "I would like to pay tribute to the contribution that Mark Anscombe made over the past two seasons and to thank him for his hard work and dedication.
"Everyone at Ulster Rugby wishes him well for the future."
"Les Kiss will have an expanded remit for the Province's Director of Rugby and will lead the coaching staff, assisted by Jonny Bell and Neil Doak and will manage 1st team selection.
"His appointment allows us time to recruit for long-term success."
Les Kiss will start work at Ulster Rugby on 19 July.
