The Manor Formula 1 team has appointed former Ferrari chief designer Nikolas Tombazis as its new chief aerodynamicist.
The 47-year-old Greek joined the Maranello squad in 2006 and was its chief designer until he left the team at the end of the 2014 season.
He starts at Manor with immediate effect and under the leadership of technical director John McQuilliam.
"I am very happy to be joining the Manor F1 team at this exciting time in its development," Tombazis said.
"The team has impressive plans and is investing in all the right areas to achieve its on-track ambitions, so I am very much looking forward to being part of that journey.
"The existing design team is already very strong and I look forward to working with a great group of people to make the most of the opportunities that lie ahead to help us progress through the field over the next few seasons."
After studying at Cambridge University and London's Imperial College, Tombazis began his career at Benetton in November 1992 under Ross Brawn, becoming chief aerodynamicist just two years later.
Brawn recruited him to Ferrari in February 1997, and he became Maranello's chief aerodynamicist in July 1998.
He joined McLaren in April 2004 as chief engineer (aerodynamics). He later became vehicle project director, but after just two years in Woking he returned to Ferrari as chief designer, and has remained a key member of the Italian team ever since.
McQuilliam added: "I am delighted to announce Nikolas in the position of Chief Aerodynamicist. I believe this appointment will help to amplify the efforts of a very talented design team that, in recent years, has not had the opportunity to showcase the full extent of their experience and capabilities.
"I am confident that, together with our new Mercedes power unit and Williams gearbox and technical partnership, our new aero structure will provide us with the strength to design and develop consistently competitive racing cars to help steer us towards our long-term ambitions."
