The 22-year-old Frenchman, the younger brother of Formula 1 driver Charles, will make his GP2 debut after competing in Formula Renault 3.5 for the past three seasons.
Pic, racing with the new AV Formula team, finished the 2013 championship in eighth position.
He has also won races and currently lies second in this season's MRF Racing series, which concludes in Chennai on February 14-16.
"We followed him closely and his future looks brilliant," said team boss Adrian Campos.
"I am sure that he will bring us great joy in terms of competitiveness. We are also working to make him feel immediately at home."
Campos returns to GP2 after taking over the Addax team entry. The Alzira-based Spanish squad competed in GP2 in its inaugural season in 2005 and stayed until 2008.
