Williams have bolstered their aerodynamics department by hiring aerodynamicists from Lotus and Red Bull.
The Grove-based squad have already made a few signings during the 2013 seasons with the signing of Pat Symonds the most noteworthy and their rebuilding process is continuing.
The team confirmed on Monday that Dave Wheater has joined from Lotus and will take on the role of head of aerodynamic performance while former Red Bull employee Shaun Whitehead takes up the post of head of aerodynamic process.
Williams Chief Technical Officer Symonds hailed the duo's arrival.
"These two appointments show our commitment to both improving the process of aerodynamic development while focussing on the application of that development to true on-track performance," he said.
"Dave and Shaun bring a wealth of experience to our team and I welcome them both to Grove and fully expect them to make significant contributions to the renewed competitiveness that we are all working so hard to achieve.
"With Dave and Shaun on board, and under Jason's stewardship, we will be well positioned to make gains in this important area and support the continuing task of developing the FW36 in what promises to be an exciting year for the sport in 2014."
