Canadian Nicholas Latifi will graduate to Formula Renault 3.5 full time with the Arden team this year.
The 19-year-old from Toronto had already competed in the series last year with Tech 1, with which he took part in three events, but his main focus had been the Formula Three European Championship.
Latifi had tested with Arden at the end of last year before securing the race seat for the upcoming season.
"I am excited for the opportunity to work with Arden for the Formula Renault 3.5 championship in 2015," said Latifi.
"From the moment I started testing with Arden in the post season, the team and I worked very well together. I am confident we will be in a position to fight for the championship right from the start.
"I can't wait for the season to begin."
Team boss Garry Horner added: "We are delighted to have Nicholas with us for the 2015 season.
"He spent some time with us during the end of season testing in November last year and we were impressed with his mature manner and his analytical instincts in the engineering of the race car."
