Simon Amor will leave his post as director of rugby at London Scottish to become England's new sevens head coach.
The 34-year-old, who won four Hong Kong sevens titles during his playing career, will lead England in the Sevens world series later this season as well as the 2014 Commonwealth Games.
"I am delighted to have been given the chance to lead England sevens at such an exciting time in the development of the sport," he said.
Amor replaces Ben Ryan in the role.
Former London Irish, Gloucester and Wasps scrum-half Amor thanked London Scottish, who begin their Championship campaign against Ealing on Saturday.
"I have thoroughly enjoyed my time putting the full-time programme in place at London Scottish," Amor added.
"The future for the club in the Championship looks very bright, and I am grateful for the opportunity they have given me to develop my career."
France legend Serge Betsen and former Leicester hooker James Buckland remain on the coaching staff with Scottish.
