Paul Monaghan is expected to leave Red Bull Racing to join the Cadillac Formula 1 project. However, according to information obtained by Motorsport.com, the Milton Keynes-based team has not yet received any formal resignation from its Head of Trackside Engineering, one of the most influential technical figures within the organisation.
The move is understood to be effectively agreed, but the absence of an official resignation explains why neither Red Bull nor Cadillac has made any public announcement so far.
Paul Monaghan has been one of Red Bull’s longest-serving and most respected technical leaders. After joining the team in 2005, he gradually became one of the key architects behind the squad’s success throughout the Christian Horner era. Although rarely in the spotlight, Monaghan has played a vital role in Red Bull’s engineering operations and has been regarded as one of the team’s most influential figures behind the scenes.
Rumours about a possible departure had already begun circulating in recent weeks, gathering momentum in the days leading up to the Austrian Grand Prix.
It was at Spielberg that those reports gained further credibility, with Cadillac now emerging as Monaghan’s next destination, effectively dismissing earlier speculation linking him with several other Formula 1 teams. Nevertheless, one final administrative step still remains before the transfer becomes official.
This weekend, Monaghan continues to carry out his normal duties inside the Red Bull garage and, at least from the outside, everything appears to be business as usual.
For Red Bull, Monaghan’s departure would represent yet another significant loss of senior personnel and further evidence of the ongoing staff departures that began following the exits of Christian Horner and Adrian Newey. The team is currently undergoing a substantial restructuring of its technical organisation, and losing an engineer with Monaghan’s experience would represent another major setback for a squad attempting to rebuild its internal structure and maintain its competitive edge.
It is also a trend that reportedly continues to concern Max Verstappen, who has witnessed several high-profile figures leave the organisation during this period of transition.
Meanwhile, Cadillac has been building its Formula 1 operation by recruiting extensively from established British-based teams. Alongside Paul Monaghan, the American manufacturer has strengthened several other departments by hiring personnel from Red Bull and across the Formula 1 paddock, particularly mechanics and engineers involved in trackside race operations.
Replacing someone with Monaghan’s level of experience will be anything but straightforward. His Formula 1 career began at McLaren in 1990, immediately after completing a Master’s degree in Mechanical Engineering. It was an impressive start to a distinguished career, as he initially worked as a data engineer alongside some of Formula 1’s biggest names, including Ayrton Senna, Gerhard Berger and later David Coulthard.
In 2000, Monaghan left McLaren to join Benetton, where he was involved during Fernando Alonso’s early years in Formula 1. Following a brief spell at Jordan, he joined the newly established Red Bull Racing team in 2005.
Over the following two decades, Paul Monaghan became one of the technical pillars of the Milton Keynes organisation, helping transform Red Bull into one of Formula 1’s dominant forces. Throughout his time with the team, he contributed to a remarkable period of success that delivered fourteen Formula 1 World Championships, cementing his reputation as one of the sport’s most respected and accomplished engineers.
If the final paperwork is completed as expected, Cadillac will secure one of the most experienced engineering figures currently working in Formula 1, while Red Bull will face yet another important challenge as it continues reshaping its technical structure ahead of the future.
