Pin began karting at the age of nine, entering national championships from 2016. She won the female karting category in 2019 and made her car racing debut in 2020 in the Renault Clio Cup France with GPA Racing, finishing second in the junior category. She joined the Iron Dames programme in 2021, a collective that supports female drivers in motorsport. Through this programme she became a member of the Iron Lynx team in GT competition and was selected for a one-day FIA Formula 3 test at Magny-Cours alongside Maya Weug, Nerea Martí, and Irina Sidorkova.
Pin's early career breakthrough came in the Ferrari Challenge Europe. After a debut outing in 2021, she ran a full season in 2022 and dominated the Pro category, winning nine of fourteen races, claiming ten pole positions, and eleven fastest laps. She clinched the title with one round remaining. That same year, Pin stepped into the European Le Mans Series with Iron Lynx, replacing Rahel Frey mid-season, and helped the team claim their first series victory at the Algarve International Circuit.
Pin made her single-seater debut in 2023 in the Formula 4 South East Asia Championship with Prema, taking three podiums including a victory at Sepang to finish second in the championship. She followed this with a partial campaign in the 2024 Formula 4 UAE Championship, also with Prema, where she secured one pole position and a race victory.
In F1 Academy, Pin entered the 2024 season with Prema Racing representing Mercedes. She was outstanding in the opening round in Jeddah, taking pole for both races and leading every lap to win Races 1 and 2 — though she was later demoted to ninth in Race 2 after a procedural error. Further wins at Zandvoort and Lusail left her runner-up overall, 121 points behind champion Abbi Pulling. Retained by Mercedes and Prema for 2025, she won at Shanghai, Miami, and Montreal, and claimed the championship title after the Las Vegas finale. She became only the third F1 Academy champion and the first French winner of the series.
Pin also competed in the Formula Regional European Championship, first in 2024 with Iron Dames alongside Marta García — a campaign interrupted by fractured ribs sustained in a cycling accident — and again in 2025 with Prema before withdrawing to focus on her Academy title chase.
In 2023, Pin entered the FIA World Endurance Championship's LMP2 class with Prema, partnering Mirko Bortolotti and Daniil Kvyat. She earned strong results throughout the season — including a podium at Sebring and a pole position at Portimão — and at the end of the year received the FIA WEC Revelation of the Year Award, becoming the first woman to win the honour. She also contested three IMSA SportsCar Championship endurance rounds that year for Iron Dames in the GTD class, posting the best lap-time averages in the GTD category at Petit Le Mans despite a mechanical retirement.
Following WEC's removal of the LMP2 class, Pin returned to Iron Dames in 2024 in the LMGT3 category with teammates Michelle Gatting and Sarah Bovy, though her season was curtailed by injury. In 2026, she joined Duqueine Team in the ELMS LMP2 Pro-Am class and was named a Peugeot TotalEnergies Hypercar development driver.
In 2024, Pin joined the Mercedes Junior Team. After winning the 2025 F1 Academy title, she was confirmed as a Mercedes Formula One development driver for 2026. In April 2026, she became the first woman to drive a Mercedes Formula One car, completing 76 laps at Silverstone in the 2021-specification W12. In May 2026, Citroën Racing named her a Formula E Gen4 development driver for the 2026–27 season within the broader Stellantis young driver programme.
Pin represents a new generation of female racing talent with genuine multi-discipline credentials. Her 2023 WEC Revelation of the Year Award and 2025 F1 Academy title established her as the most decorated female racing driver of her era across both endurance and single-seater competition. Her testing role with Mercedes made her the first woman to turn laps in a modern-specification Mercedes F1 car.
