The 20-year-old has risen through the Elite Academy system in place at the Bulls and enjoyed loan spells at Cornwall, Newcastle Thunder and Dewsbury Rams before impressing on his Bradford first team debut against Featherstone Rovers last month.
Ireland international Gill insists he will work hard to impress new head coach Kurt Haggerty, saying: “I am really happy to be staying and moving full-time with the club into Super League.
“Having got a taste of playing in the first team against Featherstone, I am looking forward to getting back in training and learning from my team mates to continue developing and pushing my stake for a place in the side next year.
“Having come through the academy and scholarship system, it is a dream to be able to make it into Super League and over the next two years I will continue working hard to improve.
“It is really exciting times for the club and I think being in a full-time environment will help me progress as a player.
“With a new coaching team coming in, it is a clean slate for everyone and I will work hard to impress.”
Haggerty said: “Jamie is a player where we can clearly see there’s a potential Super League player in there, he just needs to be in a full-time environment to see him blossom.
“He’s a big boy with a good strength of carry so we’re looking forward to seeing how he can progress and if he can turn into a future Super League player.
“The more people and players that we can have from Bradford and our Elite Academy the better, as it gives you that heartbeat of the team.
“Players like Jamie are a really good starting point for us and the more kids we can get from Bradford in a full-time environment, the better for the club.”
The club say they would like to thank Bullbuilder and their members for their continued support towards youth development at the Bulls.
