After placing fifth at the 2011 Coupe de Nice, the pair finished eighth at their first Grand Prix together, the 2011 Trophee Eric Bompard.

Finishing sixth overall, James/Ciprès were the best French pair (outscoring Popova/Massot by almost 12 points) at the 2012 European Championships in Sheffield, England.

[7] Their 2012 Grand Prix assignments were Skate America, where they placed fourth, and the Trophee Eric Bompard, where they came in sixth.

Due to their result in Canada, they qualified a spot for France in the pairs' event at the 2014 Winter Olympics in Sochi, Russia.

After Ciprès underwent surgery to correct a wrist injury, he had to avoid lifts for a period, causing the pair to withdraw from Skate America.

James/Ciprès finished fourth at the 2014 CS Nebelhorn Trophy and fifth at both of their Grand Prix assignments, the 2014 Skate Canada International and 2014 Trophée Éric Bompard.

"[11] In June 2016, James/Ciprès relocated to Coral Springs, Florida, to be coached by John Zimmerman and Jeremy Barrett, both former competitive skaters.

[12][13][1] After taking silver at the 2016 CS Autumn Classic International, the pair competed at two Grand Prix events; they finished fourth at the 2016 Skate America and won the bronze medal at the 2016 Trophée de France.

In March, James/Ciprès placed tenth in the short program, sixth in the free skate, and eighth overall at the 2017 World Championships in Helsinki, Finland.

They won medals at both of their Grand Prix assignments, taking bronze at the 2017 Skate Canada International and silver at the 2017 Internationaux de France.

James, reflecting on the start of her partnership, remarked "I'm so glad I made that choice because we're a really good team today.

Charlie White, a retired Olympic gold medalist, worked on the free skate, and fellow French Olympian Guillaume Cizeron developed the short programme.

"[19] In mid-November they competed at the 2018 Internationaux de France, where they won their second Grand Prix gold medal of the season, albeit with a somewhat rockier performance in the short program.

"[20] In fourth after the short program in the Final, they again set a world record to win the free skate and the gold medal.

"[23] In March at the 2019 World Championships in Saitama, during the short program warm-up, James had a collision with Italy's Matteo Guarise, in which both skaters fell onto the ice.

At the same time, it was announced that James would be appearing on the revival of the Canadian CBC skating competition program Battle of the Blades in the fall of 2019, partnered with retired NHL player Brian McGrattan.

[28] Zimmerman — who coached the 13-year-old as well as Cipres — was suspended by SafeSport in March 2021 for covering up the 2017 abuse, and for shaming and threatening the girl after he found out about the incident.

The allegations against Ciprès subsequently factored into the scandals that forced the resignation of controversial FFSG chief Didier Gailhaguet in the spring of 2020.

[30][28] In July 2020, the FFSG's disciplinary committee declined to take action against Ciprès, claiming that it was not aware of the alleged victim's complaint, and that there was a lack of "objective [elements] (photographs, messages, letters) that could establish proof of any offense.

"[31] On 25 September 2020, it was announced that James would return to Battle of the Blades for its sixth season, this time partnered with Akim Aliu.

[33] On 8 December 2020, the Florida state attorney's office filed a third-degree felony charge against Ciprès for the transmission of material harmful to a minor by electronic device, which carries up to a five-year prison sentence, and issued a warrant for his arrest.
