Research notes
Tom Coupland is Haas's Chief Designer. The Race's table of Haas 2025 personnel changes states that he was promoted to Chief Designer the previous year;
other public records indicate that he was earlier seconded from/joined Haas's technical organization via the Ferrari system. This role fills out the design-lead tier beneath the Technical Director.
Public records are sufficient to confirm his current title, but detailed early career history remains incomplete.
