Jaubert started karting in 2013, featuring mostly in the French championship, and stepped up to cars upon turning 16. Missing out on a seat in Porsche Carrera Cup France for 2021, Jaubert competed in the French Caterham Roadsport championship that season and the French Caterham 420R championship the following year, winning both titles and being nominated Porsche Carrera Cup France junior ahead of 2023.
Joining TFT Racing for his maiden season in Carrera Cup France, Jaubert scored his first podium of the season in race two at Magny-Cours, and ended the season with a second-place finish in race two at Paul Ricard to finish fourth in points. In 2024, Jaubert joined Martinet by Alméras to compete in both the Porsche Carrera Cup France and Porsche Supercup, along with an overseas campaign for TORO Racing in Porsche Carrera Cup Asia. Scoring a best result of seventh in Supercup at Zandvoort, Jaubert had a much better time in the French championship, taking his first win of the season at Le Castellet before sweeping the Mugello round on his way to runner-up in points behind Alessandro Ghiretti. In Asia, meanwhile, Jaubert achieved one win at Sepang and finished third in points.
Alongside his ELMS commitments, Jaubert remained in Carrera Cup competition in 2025, returning to Martinet by Alméras to race in Porsche Supercup and Porsche Carrera Cup France. In the former, Jaubert scored a lone win at the Hungaroring and ended the year with a third-place finish at Monza to take eighth in points. In the latter, Jaubert began the year by winning both races at Dijon, before winning at Spa and Valencia to end the season fourth in points.
In 2022, alongside his commitments in the French Caterham 420R championship, Jaubert also competed in the Ultimate Cup Series for ANS Motorsport, in which he took five out of six wins en route to the Group CN title. In October 2023, he had his first taste of LMP2 machinery, driving IDEC Sport's Oreca 07 at the European Le Mans Series rookie test at Portimão.
In 2025, Jaubert joined IDEC's Genesis Magma Racing-backed car to compete in the LMP2 class of the ELMS alongside Jamie Chadwick and Logan Sargeant (later replaced by Daniel Juncadella). On his debut at Barcelona, Jaubert qualified fifth, ahead of teammate Job van Uitert, before a storming drive on Sunday which earned him the Goodyear Wingfoot Award. Taking over from Juncadella in second, he passed Pipo Derani in traffic and held a commanding lead until a late-charging Matthieu Vaxivière denied him overall victory on the final lap. The trio did still score maximum points, as the race-winning AF Corse squad was an LMP2 Pro-Am entry. Jaubert went one better on home soil the next month, winning the 4 Hours of Le Castellet overall in a wet-to-dry thriller. Jaubert then won at Silverstone and ended the year with a third-place finish at Algarve to secure third in the LMP2 standings, and was named ELMS's Rookie of the Year at the season-ending awards ceremony.
