Rodolfo Gonzalez will race for Trident in GP2 and GP2 Asia this year, the team has announced.
The 24-year-old Venezuelan had previously made a one-off appearance with Trident at the Nurburgring in 2009, and also tested for the squad over the winter. He spent his first full season in GP2 with Arden last year.
"I'm really happy to have become part of the Trident Racing family," said Gonzalez. "I was persuaded this was the right choice since last season, but circumstances prevented us from being able to work together.
"I was really happy to see how much the team wanted me to be part of them, and that's been a key element in reaching the agreement. Having a team that trusts you is even more important than a great car."
Gonzalez only took two points finishes last year, but is confident he can take a big step forward in 2010.
"My dream is to end the 2011 season in the top five in points," he said.
"I know it won't be easy, but a really motivated team-driver combination can always lead to some surprise. That's what I hope for."
Trident has already signed Stefano Coletti for its other car.
