A former member of the FIA's technical department after working as an aero engineer for Prost, Ferrari and McLaren, Budkowski was enrolled by Renault F1 from 2018 as the team's executive technical director.

Budkowski worked alongside Alpine racing director Davide Brivio, with both men reporting to CEO Rossi.
