Stormers, Northampton, the Lions and now Edinburgh. South African scrum-half Nic Groom is the seventh signing of the season for former Leicester boss Richard Cockerill.
Groom, who spent two seasons with the Saints between 2016 and 2018, will join Scottish Pro14 side Edinburgh following an exciting season for the Scottish capital side under Cockerill.
"Nic has been a standout in Super Rugby and the English Premiership," said Edinburgh head coach Richard Cockerill.
"That experience in the number nine jersey is obviously key, but Nic's ability to snipe and create opportunities in and around the fringes brings a different dynamic to our squad."
Groom, 29, professed himself "really excited" by the move to Edinburgh.
"I've been keeping an eye on their results from South Africa and it's definitely a club on the rise. I can't wait to play my role in the seasons to come."
