The change comes after a series of internal restructurings started in 2024. With Andy Cowell’s promotion to team principal, replacing Mike Krack, the British engineer began to absorb much of the responsibilities that previously belonged to McCullough. Since then, the professional has remained in the organization as director of performance at Aston Martin Performance Technologies, overseeing various projects in the following months.
McCullough held the position of performance director of the Formula 1 team between 2018 and the end of 2024. During this period, he became a key figure in the team’s technical structure, being responsible for optimizing the car setup throughout race weekends.
