Former Ferrari engineering director Pat Fry has joined Manor Racing as engineering consultant ahead of the 2016 Formula 1 season.
Fry spent four-and-a-half seasons with Ferrari after leaving McLaren, holding the roles of technical director (chassis) and engineering director.
He left the team at the end of the 2014 season following a restructure of the outfit.
"We are extremely fortunate to have Pat on board to help us hit the ground running with our exciting new technical package," said Manor racing director Dave Ryan, who joined in November and previously worked with Fry when they were both at McLaren.
"The aim is to bring performance to the car with effect from the Barcelona tests, then translate that to the race track in Melbourne, to ensure we make the strongest possible start to 2016 and have a good basis for development in the early part of the season."
It continues a period of restructuring for Manor, with Fry linking up with former Ferrari colleague Nikolas Tombazis, who has been recruited as the team's chief aerodynamicist.
Manor Marussia failed to score a point last year with its outdated package and former chiefs John Booth and Graeme Lowdon left at the end of the season.
The team will race with a current-spec Mercedes power unit this season while a technical partnership with Williams will see it receive transmission and suspension components.
Manor is the only team yet to announce its drivers for the 2016 season.
