"I’m delighted to be joining a team of Williams’ history and stature in what is a very exciting time for everyone at Grove after a very impressive 2014 season," he said.
"In this role I will be able to help ensure that our operations at the race track are maintaining the highest standards and that we are maximising our performance at the race track from a sporting perspective. Williams’ has a very talented team of people and I’m looking forward to working with them."
Chief Technical Officer Pat Symonds added that Nielsen's signing shows that Williams is in a good position to improve on its 2014 campaign.
"Steve brings a wealth of experience of the sporting side of Formula One and will help us as a team as we aim to climb further up the Championship table," said Symonds.
