Williams has confirmed that Gary Paffett has joined the team for the 2016 Formula 1 season as a simulator driver.
He will assist the vehicle science department in developing the Williams Mercedes FW38, working closely with the team to provide feedback on the new car.
The British driver won the 1999 McLaren Autosport BRDC Award and has raced in the DTM series since 2003, claiming the championship in 2005 and scoring 20 victories.
He was previously a test driver for the McLaren team, completing 71 test days between 2001 and 2013. He left McLaren at the end of 2014.
"I am really pleased to be joining the Williams team as the simulator driver to aid in the development of this year’s car," he said.
"The team has such a great pedigree and history in Formula 1. I look forward to supporting the team over this year in my new role."
Claire Williams, deputy team principal, added: "We’re delighted to have someone with Gary’s experience join us at Williams.
"He is a highly professional racing driver and his level of testing knowledge, and ability to analyse data, will significantly help to drive forward development of the FW38 throughout the season."
