[9] Following a test at Bahrain near the end of 2015, Menezes signed for Signatech-Alpine to compete in the LMP2 category of the 2016 FIA World Endurance Championship, partnering Nicolas Lapierre and Stéphane Richelmi.

[12][13] As a result of his impressive debut season, Menezes was selected to drive a Porsche 919 Hybrid LMP1 car at the post-season rookie test.

However, the trio of Menezes, Tung Ho-Pin, and Thomas Laurent missed out on the overall title due to accident damage sustained at the start of the season finale.

[15] For the main 2017 campaign, ahead of which he was upgraded to gold-ranking by the FIA, Menezes returned to Signatech-Alpine for another season of the WEC, this time driving alongside a litany of other drivers throughout the year.

[19][20] In a truncated LMP1 field, Rebellion stood out as the best of the privateer entries, as Menezes, Thomas Laurent, and Mathias Beche helped the No.

[21][22] Menezes remained at Rebellion for the 2019–20 WEC season, this time partnering Bruno Senna and LMP1 rookie Norman Nato in the team's sole full-time entry.

[23] This campaign saw more success, as the trio managed to win at both Shanghai and Austin, with a runner-up finish at the postponed 24 Hours of Le Mans to boot.

Menezes and Peugeot entered the WEC season full-time in 2023, as the American joined Nico Müller and Loïc Duval in the No.
