The 24-year-old came through the ranks at the Riverside Stadium but has yet to establish himself and he is currently on loan at fellow Championship club Burton Albion - the sixth temporary switch of his career.
Darren Randolph is Boro's current number one and Ripley admits it is his long-term aim to dislodge the Republic of Ireland international and become the undisputed first-choice for his hometown club.
Ripley told The Gazette: “That is something you always strive for and something that I have always wanted. It will be a dream come true, but you have to take it step by step.
“You can’t rush these things, especially as a goalkeeper and especially with a club the size of Middlesbrough, and a club with ambitions like Middlesbrough.”
Ripley has also found first-team opportunities hard to come by at Burton as he has been restricted to just five appearances in all competitions, but he remains confident he will feature more regularly for the Brewers as the season develops.
"I know I will get my chance," he added. “Nigel Clough (Burton manager) said that I will get my chance at Burton and I will hold him to his word.”
