Eysseric began his career playing for a host of youth clubs before settling at Monaco in 2007. In June 2010, he signed a three-year élite contract, which was due to become a professional contract in June 2013, with the club. In the following season, he was a member of the Monaco under-19 team which won the 2010–11 edition of the Coupe Gambardella. He made his professional debut in Monaco's first competitive fixture of the 2011–12 campaign, a 4–1 loss to Sedan in the Coupe de la Ligue. On 16 September 2011, he scored his first goal for Monaco in a 1–1 draw against Bastia. On 9 December 2011, he scored his first Coupe de France goal in a 2–1 win over La Tour-Saint Clair. Having established himself in the first team, Eysseric run continued before falling out of favour with manager Marco Simone and being sent to the reserves. The next season, he would make two appearances for Monaco before moving to Nice.
On 23 August 2012, Eysseric joined Ligue 1 side Nice on a loan deal, until the end of the season. On 2 September 2012, he made his Ligue 1 debut against Bordeaux, a 1–1 draw. In his next appearance on 15 September 2012, he scored his first goal in a 4–2 win over Brest. At Nice, he since established himself in the first team and continued scoring goals including a winner in a 2–1 success over PSG and two goals in two consecutive games in Coupe de la Ligue against Brest and Lyon. In January 2013, he signed for the club on a permanent basis, on a contract keeping him until 2017. Four days before signing a permanent basis, he scored a brace in the first round of Coupe de France, as Nice win 3–2 against Metz. his first game after signing for the club on a permanent basis with a fee of 1.5 million euro, scoring his third goal, as Nice won 5–0 win against Valenciennes.
Eysseric received a straight red card for breaking the leg of Saint-Étienne player Jérémy Clément with a brutal tackle on 3 March 2013, in a Ligue 1 match which Saint-Étienne won 4–0. After the match, he apologised and showed regret for his actions. He also said the tackle ruined his reputation and said: "I am wrong in my head and I still feel guilty, I had no right to try this gesture and I can only apologize again for having injured him [Clément]. I saw [the images] to understand them and I have not found an explanation. But it's over. I will not look at them anymore. It's too hard. The images haunt me. Since Saturday, I've had flashes where I see the ankle of Clément completely at right angles.". His tackle on Clément caused the injured player to be out for the rest of the season. This also led the Ligue 1 disciplinary committee to give Eysseric an eleven-game ban, keeping him out for the rest of the season. Soon after, Eysseric told L'Équipe that he would not appeal his eleven games ban, insisting that was the disciplinary committee's decision.
On 31 January 2019, the last day of the 2018–19 winter transfer window, Eysseric returned to France joining FC Nantes on a loan deal until the end of the season. Nantes also secured an purchase option to make the signing permanent.
