Jorda, who finished 29th in last year’s GP3 feeder series, said: “It feels like a dream come true.”
Her role is the same as Susie Wolff’s at Williams last year before the Scot was promoted to test driver in 2015.
“I’ve been racing since I was 10 years old so it was my dream to drive a Formula 1 car since I was very young,” Jorda added.
“Joining Lotus F1 Team is a big step towards my goal. I will be working to improve myself as a driver as well as helping the team to develop the car by testing new developments in the simulator; it’s such a fantastic opportunity.
“I know this is just the beginning and the biggest challenge is yet to come but already being part of a team with such a history is a real honour.
“This is a great achievement, but an even greater opportunity which will lead to bigger and better things.”
