Manor has added to its leadership team by appointing Renault's chief operating officer Thomas Mayer to the role of CEO.
Manor has undergone significant changes since its return to the grid at the start of last season, when it remarkably returned from bankruptcy which caused it to miss the final three races of 2014. Last year sporting director Graeme Lowdon and team boss John Booth quit the team after a difference of opinion with owner Stephen Fitzpatrick.
After securing Mercedes engines for the current campaign, the team recruited Dave Ryan to the role of team principal in late 2015 and has continued adding new names, confirming Mayer on Thursday.
"This is a time of growth and development for Manor Racing," Fitzpatrick said. "We've been pushing hard to get the team back on track -- figuratively and literally -- and our recent point-scoring performance in the Austrian Grand Prix shows that we're making progress.
"Thomas will bring people together and help us focus clearly to accelerate improvement. He brings highly relevant F1 business experience, as well as a strong engineering background, and he shares our passion to succeed and challenger spirit. I'm delighted that he has agreed to join the team to spearhead our longer term strategy."
Mayer's time in F1 started with Lotus in 2012, remaining at Enstone through its takeover by Renault in December.
Commenting on his new role, he said: "I am excited to join Manor Racing, a team with the capability to fight for points and push the boundaries. I am looking forward to making the name Manor Racing synonymous with an unconventional and innovative approach to achieving performance."
