Red Bull Hires Tom McCullough — and the Pit-Wall Rebuild Around Verstappen Gets Serious
GOATIFYRed Bull’s next phase is starting to look less like a simple personnel shuffle and more like a deliberate rebuild of the operation around Max Verstappen. The team has hired veteran engineer Tom McCullough as its new Head of Racing, with the 50-year-old Briton set to begin the role at the start of 2027 after leaving Aston Martin.
On paper, the move adds another experienced operator to a team that still has elite talent everywhere. In practice, it matters because McCullough is arriving at a moment when Red Bull’s trackside structure is changing quickly. Gianpiero Lambiase, Verstappen’s long-time race engineer and Red Bull’s Head of Race Engineering, is due to leave for McLaren and become its Chief Racing Officer. Other technical and performance roles have also been reshaped as Red Bull tries to make its next leadership structure more stable than the one it has been dismantling.
McCullough brings exactly the kind of background that fits that job. He has spent more than two decades in Formula 1 and senior motorsport engineering, worked across Williams, Sauber, Force India, Racing Point and Aston Martin, and built a reputation around extracting performance from race weekends rather than living only in one narrow technical department. His arrival is therefore not just about replacing one departing name. It gives Red Bull another experienced bridge between engineering, strategy, drivers and the trackside operation.
McCullough’s career has been built around making race weekends work
McCullough’s path to Red Bull is unusually broad. His motorsport career began at Reynard, where he worked on projects spanning Le Mans and IndyCar research and development before moving into Formula 1 with Williams in 2002. At Williams he progressed from data engineering into race engineering, working with drivers including Nico Hülkenberg, Rubens Barrichello and Bruno Senna.
That decade matters because it gave him experience in the part of Formula 1 where decisions have to happen in real time. Race engineering is not simply about understanding the car. It is about translating telemetry, driver feedback, tyre behaviour, traffic, weather and strategy into decisions quickly enough for them to matter. Engineers who spend years in that environment develop a different kind of operational instinct from those who work primarily on long-term design programmes.
After leaving Williams at the end of 2012, McCullough spent a season at Sauber as Head of Track Engineering before joining Force India in 2014 as Chief Race Engineer. Four years later he was promoted to Performance Director. That period covered some of the strongest results in the Silverstone-based team’s history: Force India finished fourth in the Constructors’ Championship in both 2016 and 2017, while the Racing Point version of the organisation won the 2020 Sakhir Grand Prix.
When the team became Aston Martin, McCullough remained in a senior performance role. His job increasingly involved coordinating what happened at the circuit with the performance groups back at the factory, making sure both cars had access to the best information available during a race weekend. That kind of cross-department responsibility is highly relevant to Red Bull’s new Head of Racing position because the fastest car in a wind tunnel is still useless if the trackside organisation cannot convert it into qualifying laps, pit stops, tyre calls and race execution.
McCullough’s role changed during Aston Martin’s 2025 restructuring. He moved away from the direct Formula 1 operation and into Aston Martin Performance Technologies, where he continued in a senior performance position across wider motorsport projects. His departure from the group was confirmed during 2026, opening the door for the Red Bull move.
Red Bull is rebuilding the layer between the car and the driver
The timing is what makes the appointment more significant than a normal senior hire. Red Bull knows Lambiase is leaving. For years, his role has been unusually important because he has combined the direct race-engineer relationship with Verstappen with broader responsibility as Head of Race Engineering. McLaren has lined him up to become its Chief Racing Officer, with his move expected by 2028 at the latest.
That creates two separate problems for Red Bull. One is personal and driver-facing: replacing the voice that Verstappen has heard through some of the most successful seasons in Formula 1 history. The other is organisational: redistributing the wider race-engineering responsibilities Lambiase has carried inside the team. Those do not necessarily have to be solved by the same person.
McCullough’s Head of Racing title suggests Red Bull is thinking about the second problem at a broader level. His experience sits above the job of one car’s race engineer. He has managed trackside engineering groups, coordinated performance departments and operated in organisations where getting the most from limited resources was essential. That makes him valuable even if Verstappen ultimately works directly with a different engineer on the radio.
It also fits a wider Red Bull reshuffle. The team has changed parts of its technical structure, including design and performance leadership, while Laurent Mekies continues to oversee the operation. Red Bull is trying to retain the aggressive execution that made it so difficult to beat while reducing dependence on a small number of individuals whose departures can destabilise multiple areas at once.
That is a crucial distinction. During the dominant Verstappen years, Red Bull often looked almost frictionless from the outside. Strategy calls were sharp, pit stops were fast, qualifying preparation was usually controlled and Verstappen’s communication with Lambiase was brutally direct without becoming dysfunctional. When a team operates at that level for long enough, the system can start to look automatic. It never is. It is the product of people, processes and trust built over thousands of decisions.
McCullough will inherit the challenge of protecting that decision-making quality while the personnel around it changes. Red Bull does not merely need another accomplished engineer. It needs someone capable of making a new group behave like an experienced one quickly.
Verstappen makes the transition harder — and more important
Any major operational change at Red Bull has to be judged partly through Verstappen because he is not an ordinary driver to integrate into a new system. He has spent years operating with a highly specific rhythm. His feedback is concise, his tolerance for confused communication is low, and his relationship with Lambiase has worked precisely because neither side needs to soften the message when the car or strategy is wrong.
Red Bull’s challenge is therefore not to recreate Lambiase by finding another engineer with the same personality. It is to make sure the next structure gives Verstappen the same confidence that the people around him understand what he needs and can act on it immediately. That requires strong communication between whoever becomes his direct race engineer, McCullough’s wider race leadership and the engineers back at Milton Keynes.
The 2026 regulations make that integration even more important. The current cars place different demands on energy management, active aerodynamics and race execution than the previous generation. Drivers and engineers are still refining how to extract the best from the package across different circuits. A senior operator joining in 2027 will not have the luxury of treating the new rules as new anymore; he will be expected to arrive with the team already possessing a full season of data and immediately help turn that information into better weekends.
For Red Bull, McCullough also represents something valuable that cannot be simulated: experience of other organisations. Williams, Sauber, Force India and Aston Martin all approached Formula 1 with different resources, cultures and competitive pressures. McCullough has seen how strong systems are built, how weaker ones fail and how teams can outperform the raw quality of their machinery through execution.
That perspective is useful for a Red Bull organisation trying to evolve after a period when its own way of working became the benchmark. The danger for any dominant team is assuming the processes that produced yesterday’s success will automatically produce tomorrow’s. Bringing in a senior engineer from outside forces some of those assumptions to be challenged.
The appointment will not guarantee that Red Bull gets the transition right. There are still unanswered questions around the exact division of responsibilities once Lambiase leaves, who will be closest to Verstappen during race weekends and how quickly the new leadership group settles. But hiring McCullough early gives the team time to plan rather than improvise.
That may be the most important part of the move. Red Bull already knows one of the central figures in its trackside operation is heading elsewhere. Instead of waiting for the vacancy to become a crisis, it has added a veteran with a career built around race engineering, performance management and trackside coordination. For a team whose championship ambitions still revolve around Verstappen, that is exactly the area where continuity matters most.
