Roy Nissany gained a strong motorsport interest at a young age and started driving go-karts professionally aged six. After a successful karting career, Roy stepped up to Formula BMW Junior in 2010, where he scored a victory after starting tenth on the grid at the legendary Monza circuit.

From 2011 to 2012, Roy raced in the ADAC Formula Masters, scoring multiple podiums which helped prove his potential and secure a seat in the FIA Formula 3 Championship. While racing in Formula 3, he obtained top ten finishes, which led to his first test in a Formula One car, with the Sauber F1 Team.

In 2015, Roy began racing in the World Series 3.5, where he would stay for three full seasons and collect trophies year in and year out.

In 2018, he began his FIA Formula 2 Championship campaign, obtaining two top ten finishes. An unexpected training injury, at the start of 2019, led to a short break from racing for rehabilitation. In 2020 Roy returned to race in FIA Formula 2, alongside his Williams Racing Driver Academy commitments.

In 2021, Roy joined DAMS and secured his first F2 podium, finishing third in the Monaco sprint race.

He will remain with the French team in 2022.
