Andrew Alessi has joined the team as head of technical operations where he will lead, manage and develop the design, planning, production and operations of the aerodynamic department.
Alessi's arrival is the latest in a string of appointments as Aston Martin bolsters its backroom staff.
That has seen technical director Andrew Green promoted to chief technical officer.
The internal promotion of Tom McCullough has seen him take on the role of performance director, while Luca Furbatto will become engineering director.
Alessi's former Red Bull Racing colleague, Dan Fallows, is set to join as technical director once his contract with the championship-winning squad expires.
“I am delighted to be joining Aston Martin Cognizant Formula 1 Team as head of technical operations,” said Alessi.
“Like everyone in and around Formula One, I have seen and been impressed by the evident ambition of the team I am joining, led as it is now by Lawrence Stroll [executive chairman], and I am very much looking forward to working with Otmar Szafnauer [team principal and CEO] as well as the very capable technical- and engineering-focused members of the senior management team.
“Now is a fantastic time to be joining a team that is growing fast, and I am ready to get stuck in straight away so as to contribute to the process of making the significant aerodynamic and operational improvements that we need in order to win consistently in the future.”
Szafnauer added: “Two weeks ago we announced the hiring of Luca Furbatto as our new Engineering Director, who will start work for us in due course.
“Last week Dan Fallows' forthcoming arrival as our new technical director was also made public.
“Today, Andrew Alessi is added to the impressive list of our senior technical/engineering hirings, as head of technical operations. Ours is a great team, and it always has been.
“This year it became Aston Martin Cognizant Formula One™ Team, a great brand name supported by a fantastic roster of brilliant new sponsor-partners.
“Many times this year we have said: ‘This team has always punched above its weight; now it has the weight with which to punch harder'.
“That is absolutely true – and expert and experienced new arrivals such as Luca, Dan and now Andrew represent proof that we are building the technical/engineering strength in depth that we need in order to deliver that harder punch.”
