The East Kilbride RFC product has made six appearances to date this season, having made his debut for the Warriors when coming off the bench in October's 37-0 victory over Benetton at Scotstoun.
Comfortable in either the second-row or the back-row, Ferrie has primarily operated at blindside for Franco Smith's men, including starting in the back-row in January's EPCR Challenge Cup clashes against USA Perpignan and Bath - his first outings in European competition.
Ferrie - who has also represented Hamilton Bulls and Glasgow Hawks during his rugby career to date - has been a part of the Boroughmuir Bears squad for the FOSROC Super6 in both 2021 and 2022, making 13 appearances for the Meggetland outfit.
"Honestly, signing my first professional deal has just given me such a buzz," Ferrie told glasgowwarriors.org following the announcement.
"I remember coming to Glasgow matches when I was a kid, so to be standing here as a professional means so much to me. It's been some path to get here and I'm so grateful for the opportunity.
"It feels really good to know that the coaches trust me to go out there and represent this club, and it means so much to pull on the shirt whenever I get the chance.
"The senior pros here have really helped me a lot this season, too. Just being able to be around them day in, day out and focus on areas of my game that I need to improve upon really sharpens my game and helps me get better.
"I just want to play as many matches as I can for this club, and get as many minutes under my belt as possible. I want to help this club win, and hopefully get us challenging for silverware."
Head Coach Franco Smith added: "Euan is a talent that has impressed us across this season so far and has earned his first professional contract.
"He's a young player who is eager and willing to learn in all aspects of his game, and has bought into what we are trying to build here at Scotstoun
"We look forward to continuing to help him develop and grow as a player and as a person over the rest of this season and beyond."
