The 24-year-old - who will link up with his new club subject to visa - joins fellow signing Duncan Weir and FOSROC Scottish Rugby Academy graduate Ross Thompson as the club's options at number 10, in a back-line that will also be able to boast new arrivals such as Josh McKay and Sione Tuipulotu.
Born in Tucuman, Miotti burst on to the scene in 2019 with one of the most remarkable Super Rugby debuts in recent years; with the Jaguares trailing to the Bulls with 10 minutes to play, his two late tries saw the Argentinian franchise claim a stunning victory at Loftus Versfeld.
That debut firmly established the fly-half in the Jaguares squad that were only denied a famous Super Rugby title by the Crusaders, with Miotti coming off the bench in the 2019 Super Rugby final in Christchurch.
In total, he made 16 appearances for the Argentinian franchise, scoring 107 points across two seasons with Gonzalo Quesada's men.
A move to Western Force for the 2021 Super Rugby AU season followed, with the fly-half joining a back division including established internationals such as Tevita Kuridrani and Rob Kearney.
Miotti made his senior international debut in the 2020 Rugby Championship, coming off the bench to score a crucial eight points in December's 16-16 draw with Australia in Sydney.
The former Tucuman LT man has also represented his country at 'A' and U20 levels, as well as appearing in an Argentina jersey at World Rugby 7s Series events in Dubai and Cape Town in 2016.
He will become the eighth Argentinian international to represent the Warriors, following in the footsteps of Francisco Leonelli, Bernardo Stortoni, José María Núñez Piossek, Federico Aramburu, German Araoz, Gabriel Ascarate and - current Warrior - Enrique Pieretto.
Signing with the Warriors, Miotti told glasgowwarriors.org: "I'm very excited to join Glasgow.
"They are a great club and playing in the Guinness PRO14 will be a new experience for me that I'm really looking forward to.
"I've watched some of Glasgow's games and they play a fun attacking style of rugby that I'm excited to be a part of.
"My focus for this season is to give my all for the Western Force, and when the tournament is over, focus on Glasgow Warriors."
Head Coach Danny Wilson added: "Domingo is an exciting attacking prospect for us.
"He's a young Argentinian international with strong kicking game and good ball handling skills.
"He adds further quality to our backline and we're looking forward to welcoming him to Scotstoun in the summer."
