Alex Wurz will return to the Williams team as a driver mentor, the Grove-based squad announced on Monday.
Austrian Wurz raced for Williams during the 2007 season, and he will be reunited with his old team when he starts his new role in the upcoming Barcelona test.
Williams said Wurz will travel to races this year, helping race drivers Bruno Senna and Pastor Maldonado.
"This is a great initiative by Williams and highlights just how hard the team is pushing to optimise its performance," said Wurz.
"Throughout my career as a sportsman, which started at the age of 12 in BMX racing, includes over a decade in Formula 1 and is still ongoing (racing in the World Endurance Championship), I am lucky to have gained so much experience.
"I grew up in a family business of driver training and naturally I enjoy helping fellow athletes to operate at their best.
"I'm really looking forward to using my expertise to help Williams at this important stage in its history."
Engineering chief Mark Gillan added: "I am delighted to be working once more with Alex and look forward to his valuable input with the drivers as the whole team strives to continuously improve in all aspects of its operation."
