He told the club's official website: "It has been a great experience, an honour and privilege to have been here as assistant manager for the past year.
"Tynecastle is a special place and I will always retain fond memories of the stadium and particularly the supporters. They have been phenomenal this season and I'm only disappointed that we didn't have a better campaign for them.
"I have enjoyed my time here and I'm sure it will prove of great benefit as I look to continue my career off the park."
