British racer Alex Lynn has joined Williams as their new development driver for the 2015 F1 Championship.
The 21-year-old, who won the GP3 Championship last season, will spend time in the Williams simulator, helping with the ongoing development of the FW37.
He will also assist the race engineers in setting up the car for grand prix weekends and take part in a day's testing at the Barcelona circuit following the Spanish GP.
"I am extremely excited to be joining Williams, a team with such incredible history and amazing potential," said Lynn. "Over the past year the team has made huge strides forward and it's clear to see their determination to fight for more success in the future.
"I hope that with a strong year in GP2, while also helping to develop the F1 car throughout this season, I can follow in the footsteps of Valtteri Bottas who joined the Williams team in exactly the same Development Driver role. Through hard work and determination, he has gone from winning the GP3 title to earning his place as a Williams F1 race driver.
"Working with people like Sir Frank Williams and Pat Symonds is an incredible opportunity for me. There is so much experience here at Williams and I hope to be able to use the knowledge gained from these people to further develop my skills as a racing driver and respected member of this team.
"Everyone has been incredibly welcoming from the outset, we have hit the ground running and I am very excited about the challenges this role offers – particularly my on track activities driving the FW37 in a few months time."
