Former Jaguar racing driver Alex Lynn will return to the team as test and reserve driver.
Lynn replaced Nelson Piquet Jnr at the team midway through last year, running alongside race winner Mitch Evans. He took two top 10 finishes from seven races, with a best result of seventh at Bern.
He was replaced for the 2019-20 season by James Calado, who took a P16 and P7 from he Diriyah double header.
"Mitch Evans and James Calado are an exciting combination and they will be strongly supported by Alex throughout the season," said team boss James Barclay.
"Alex is not only a very talented and accomplished driver, he also has valuable experience in Formula E and a great relationship with our team. That experience and relationship will be highly beneficial to our ongoing development.
"Winning races can only be achieved if you have a hard working, talented team around you. Bringing Alex back into the fold helps us achieve that."
Lynn made his Formula E debut in 2017, standing in for Jose Maria Lopez at Virgin for the New York double header. He claimed pole position for his debut, but suffered a double retirement.
Returning to the team for the 2017-18 season, Lynn finished 16th in the championship standings with a best result of sixth in Punta del Este.
"I am excited to be re-joining the Panasonic Jaguar Racing team and returning to Formula E," he said. "I am familiar with the championship ,the team, their goals and how they work. I look forward to playing my part in helping the team achieve their objectives."
Lynn replaces former reserve driver Ho-Pin Tung, who remains at the team as a Jaguar Racing global ambassador.
