Michael Jolley has left his U23 coaching post at Burnley to take charge of Swedish side AFC Eskilstuna.
It will be the 40-year-old's first senior management role and ends a three-year stay in East Lancashire.
He said: “I am incredibly grateful to Sean Dyche, his staff, and all the people at Burnley FC for three fantastic years at this unique football club.
“The manager has been a huge influence on me and it has been a privilege to serve as a member of his staff.
“I think we have made some genuine progress in the last three years with regard to young players graduating to the first team, or playing league football on loan, and the club is perfectly placed to build on this with the achievement of Category 2.
“I have been fortunate to work with some fantastic young players, and some outstanding staff, notably my assistant Andy Farrell, during my time at Burnley."
