Former Force India chief race engineer Dominic Harlow has moved to Williams.
Harlow has been appointed to the role of senior operations engineer with the Grove based team and is attending this week's Jerez test in his new role.
"Race weekend support is an area that we are very keen to enhance," said chief operations engineer Mark Gillan. "Dominic is a strong new addition to the team coming into the race operation side. He's already bringing good new ideas so I'm very pleased to get him on board. We are always looking for good talented engineers."
Harlow had been with Force India since joining it in its Jordan guise in 2005 and held the role of chief race and test engineer from 2007.
