Aston Martin F1 has been going through a lot of changes over the last year, consistently shuffling its technical leadership, and now another adjustment to the staff is happening.
Long-time engineer Tom McCullough, who has been with Aston Martin since the team was known as Force India, will be stepping aside from the team altogether.
McCullough has been around the F1 project for more than a decade, working trackside on performance elements of the racing outfit.
He took on a role in the business arm of the team at the start of 2025, joining the senior leadership off the track, but now McCullough is fully stepping away.

Former team principal Mike Krack assumed the Chief Trackside Officer role ahead of the 2025 season.
McCullough will finish out the current season with Aston Martin, per F1 correspondent Lawrence Barretto, before leaving.
At this point, it is unclear what kind of future McCullough is aiming for, either pursuing other interests or stepping into a new role with a new team.
What changes are happening with Aston Martin?
Adrian Newey took over as the team principal following Andy Cowell, the former leader of the racing project, becoming the chief strategy officer.
Newey started the season in the role, though Aston Martin’s season has not gone as planned, with terrible results and overall race performances.
He is one of the more highly regarded engineers in the sport’s history, and while he has leadership experience, this is his first time in this kind of role.
There are rumors Aston Martin could hire someone to fully take over the team principal duties, but until then, it will be up to Newey, who is optimistic about what the team can do in the future.
“The key one for us is that front‑of‑floor change. It gives everyone a different aero challenge to solve,” Newey said.
“Because we’ve effectively been forced to grow up quickly as a team over the last 12 months, we’re in a much better place to capitalize on the regulation changes than we would have been a year ago. We’re a much more mature organization now, and that leaves me very optimistic about what’s to come.”
