“I have absolutely loved my time with Williams so far and could not be more delighted to continue working with the team in my role as Development Driver," said Chadwick.
"I feel I am improving as a driver all the time, and my time spent in the simulator this coming season will prove to be invaluable. I look forward to fully immersing myself at Williams once again this year.”
Williams has said the 22-year-old will "increase her simulator programme" this year and will "support the team across its media marketing activities throughout the season".
Team principal Simon Roberts added: “We are delighted that Jamie will continue as a Development Driver for the team.
"Not only is she a great female ambassador for the sport and plays an integral part in promoting women in motorsport, her work in the simulator and behind the scenes at Grove is hugely valuable.
"Jamie’s determination and drive to do more, as well as push the boundaries, is something we admire at Williams and we are all looking forward to the year ahead with Jamie as part of the team.”
