The Spaniard was a factory-based engineer in 2018 before becoming a race engineer when Leclerc joined Ferrari the following year.
Marcos remained in the position until May 2024, when he was replaced by Brian Bozzi ahead of the Emilia Romagna Grand Prix and what were described by Ferrari as “other important company events”.

The second new job is that of propulsion manager, with a focus on the 5.5-litre normally aspirated V8 and spec hybrid system powering the V-Series.R.
The position is taken by Sean O’Shea, who joined Cadillac parent company General Motors in 2015.
He previously worked for Bosch Motorsport, supplying the motor generator unit of the LMDH hybrid system when involved in Mazda’s diesel racing programs in sports cars.
Bosn takes over management of the V-Series.R campaigns from Laura Vontrop Klasser, who was GM’s sportscar program manager covering both the LMDH and Corvette Racing GT3 programs.
That role has now been split, with Jessica Dane, daughter of Roland, co-founder of the Triple Eight Engineering touring car team in the United Kingdom and Australia, taking over as manager of the Z06 GT3.R project.
Clouser and Christy Bagne, who worked under him on the Z06, have been moved into production car roles within GM. These moves were described as a general rotation or “churn” of management within the GM Racing unit.
