Research notes
Most thoroughly documented of the three (Wikipedia + Liquipedia + multiple news outlets). Verified: Spanish nationality;
career path BNC -> HRT (2010, F1 debut) -> Williams/Massa -> NASCAR/Richard Childress Racing -> Ferrari (2018, then Leclerc's RE 2019-May 2024) -> Cadillac sportscar TD (Jan 2025) -> Cadillac F1 Chief Race Engineer (announced 22 Dec 2025). Uncertain: education/university unknown (not found in any source);
exact 'years_to_race_engineer' depends on definition - he was a chief race engineer in NASCAR from 2015 and an F1 race engineer from 2018/2019, so the value 9 (2010 F1 debut -> 2019 Leclerc RE) is approximate. Cadillac is a brand-new 2026 entry, so this is a recent hire. He is the department head / chief RE, not assigned to a single car, so drivers_2026 lists both.
