Rayo was born in Elche. He finished his formation with local Valencian Community club Elche CF and played only Segunda División B football until the age of 25, representing Villajoyosa CF, FC Barcelona B, Orihuela CF and UE Lleida.
In the 2011 summer Rayo moved straight into the Superleague Greece, joining a host of compatriots at Asteras Tripoli FC. He scored five league goals in his first season, adding three in the campaign's domestic cup.
In 2012–13, Rayos improved his overall totals to nine goals and 12 assists. In the final of the Greek Cup, against Olympiacos FC, he put his team ahead 1–0, but in an eventual 1–3 extra time loss; during most of his spell in Greece, he was also club captain.
At the end of Season 12/13 Rayos was named as the best player of the league.
On March 9, 2014, during the 25th cycle game against Bnei Yehuda, Rayos brutally tackled opposing midfield player Rafi Dahan, severely wounding him with a cruciate ligament rupture. Rayos was sent off with the referee showing him a direct red card. Following the incident, many Israeli players have issued statements condemning the action of the player.
