The 19-year-old, who has been racing in the junior GP3 series, will drive a Formula One car for the first time in Abu Dhabi testing after next week's season-ending grand prix.
Force India said the Mexico City-born driver, who has had one podium finish in GP3 so far, will also carry out simulator work.
"As our development driver we will work hard to prepare him for the demands of driving in Formula One and provide a good grounding in all aspects of the job," said team co-owner Vijay Mallya in a statement.
Force India already have experienced Mexican driver Sergio Perez racing for them along with Germany's Nico Hulkenberg and are also backed by several Mexican sponsors.
