[5][2] Masi alternated in this role between Grands Prix with Scot Elkins, who would become the race director for Formula E and the Deutsche Tourenwagen Masters.
[6] Following Whiting's death before the 2019 Australian Grand Prix, Masi took on the role of Formula One race director.
[13] The following week, Masi's failure to correctly apply the re-start rules in the resumption of the race following a safety car period during the final lap of the 2021 Abu Dhabi Grand Prix was criticised for potentially altering championship results.
[14] On 17 February 2022, Masi was removed from his role as Race Director following an FIA analysis into the Abu Dhabi Grand Prix.
[15][16] He was replaced by Niels Wittich and Eduardo Freitas as race directors on an alternating basis for the 2022 Formula One season, and Herbie Blash as Permanent Senior Advisor to them.
[24] Due to the abuse and death threats he received after the Abu Dhabi Grand Prix and the exhaustion of travelling to different countries as race director, Masi sought help with his mental health.
