Kent's academy director Paul Farbrace has been appointed as new Sri Lanka coach Trevor Bayliss's assistant.
Farbrace starts in his new role next month
The 40-year-old has also served as coach of the England women's and men's Under-19 teams in the past.
Bayliss, who was named as Tom Moody's successor in June, recommended his appointment to Sri Lanka Cricket.
"It has been a difficult decision to make because I am really enjoying the job here at Kent," Farbrace, who has agreed a two-year contract, said.
"There is real talent within the Kent system and I believe there a number of our youngsters who could make a significant impact on Kent cricket in the future.."
Kent director of cricket Graham Ford added: "Paul has made a major contribution to the development of our youngsters during his time with us and it will be sad to see him go.
"In many ways it is a compliment to both Paul and the club that he should have been selected for such a prestigious post."
Farbrace's first task will be to help Australian Bayliss prepare Sri Lanka for the World Twenty20 tournament in South Africa in September.
Moody left after the 50-over World Cup in April, in which the team lost in the final to Australia.
Sri Lanka were coached for an interim period by his assistant Trevor Penney, who oversaw the 3-0 Test series triumph over Bangladesh but is now moving to Western Australia to again link up with Moody.
