On 24 April 2014, he signed a three-year deal with Paris-Levallois, but was loaned to Hyères-Toulon of the Pro B. He started the season being a solid rotation player with Davante Gardner.

For the 2015–16 season, he returned to Paris-Levallois. From December onward, he was subject to a special designation allowing him to be able to play both with Paris-Levallois, and with CFBB in National 1. In December 2015, Frédéric Fauthoux replaced Antoine Rigaudeau as coach, which allowed Poirier a greater chance to show his potential. In April 2016, he was named MVP of the Round after finishing the match against BCM Gravelines-Dunkerque with 23 points, 12 rebounds and 2 assists in 25 minutes, when he started the game as a backup.

On 11 September 2016, as part of the pre-season, he and his team won the Sarthe/Pays de la Loire trophy in a three-team tournament by beating Le Mans and Antwerp Giants.
On 14 June 2017, Poirier signed a three-year deal with Saski Baskonia of the Spanish Liga ACB and the EuroLeague. In the 2018–19 season, Poirier led the EuroLeague in rebounding, averaging 8.3 per game. On 10 May 2019 Poirier earned a spot in the All-EuroLeague Second Team.
