Research notes
Name spelled 'Gaëtan Jego' on Wikipedia and the official Williams site (some outlets render it 'Gaetan Jago'). Pairing with Carlos Sainz for 2026 (second season together) confirmed across RacingNews365, Motorsport.com, Wikipedia and the Williams site. French;
studied at ESTACA per multiple sources, though exact degree level/years not publicly stated. f1_debut_year 2020 (joined Williams as Latifi's race engineer);
he entered F1 directly into a race-engineer seat after ~15 years in junior formula and sportscars, so years_to_race_engineer = 0. Internal ART role-transition years (GT 2013-14, DTM/LMP1 2015-19) are approximate from prose summaries and not all precisely dated in sources.
