The 26-year-old has been one of the shining lights at fullback for most of this season for the Titans after regular No.1 Keano Kini suffered a long-term neck injury in round three.
Brimson started the season at five-eighth, but has played fullback with success in previous years before New Zealand custodian Kini burst on the scene.
Kini is signed long-term and when he returns next year Brimson may be on the move again.
"Each year it is always a surprise coming in and seeing what is going to happen but I guess the club has that planned going forward," he said.
"Last year I did my whole pre-season at centre. This year I did my whole pre-season at six and I am obviously playing fullback at the moment.
"I do love fullback but I love winning games more. If that is me at six and Keano at one I just want to be doing better than we are at the moment.
"Footy is only frustrating when you are losing. At the start of the year I was six and we won two from three and I was happy because we were winning."
Brimson said it was not an option for him to look at moving elsewhere to play fullback for a very good reason.
"I am signed until 2030 so I just want to win games at the Titans," he said.
The Titans, who host four-time defending premiers Penrith on Saturday, sprung one of the upsets of the season when they beat the fourth-placed Warriors 24-16 in New Zealand last round.
It was coach Des Hasler's 500th as a mentor in the NRL.
"We spoke, without Des in the room, before his 500th game and how important it was for us to try and get a win," Brimson said.
"The team loves and respects Dessie and we spoke about trying to make it special for him, which he is not big on. He's a pretty humble guy when it comes to that milestone.
"We had a little chat to him individually after the game and I think he was happy and proud."
Hasler is under pressure to retain his job beyond this year but Brimson said he had not noted any change in the coach's committed, and at times eccentric, ways.
"Dessie is Dessie ... a mad professor or scientist or whatever they call him. He is still just as invested and scary and funny as always," Brimson grinned.
