Inverness-born Mattinson said: “I’m incredibly excited to be starting a full-time coaching role and grateful for the opportunity to continue working in the game I love.”
Mattinson started her career with Worcester Warriors and went on to play for Gloucester-Hartpury and Edinburgh.
She began her international career by earning seven caps for England, but a change in eligibility rules allowed her to switch to Scotland in 2022.
“Rugby has always provided me with a sense of belonging, thanks to the people I’ve played alongside.
“Never more so than with Scotland, whose shared love for our wee country, and each other, has given the best friendships for life.
“It could never be overstated just how special that group is.”
However, it is a group left in turmoil amid the contracts row and the departure of Bryan Easson after five years as head coach.
“Rugby has been my whole world for as long as I can remember. I’ll be forever grateful for the journey that I’ve had,” Mattinson said.
“I’ve been very lucky to be coached and supported by incredible people along the way.”
In particular, she picked out former Worcester Warriors boss Jo Yapp, describing her as “the most incredible coach I’ve ever known, who’s never failed to put her players first”.
