McJoe was born along his twin brother, McWilliams, in the municipality of Ceiba in the northeast coastal region of Puerto Rico's main island. Arroyo and his twin, were introduced to boxing in their childhood. At the age of 12, they entered Gimnasio Fito Ramos, a gymnasium located in the municipality of Fajardo, Puerto Rico.^[2] In this locale they met Anthony Otero, a retired amateur boxer, who became their trainer during this stage of their careers.^[3] They initially took up the sport as a hobby, but after six fights they began establishing a pattern of only spending a limited amount of time inactive during a month, visiting the gymnasium at least every two weeks.^[4] Since the early stages of their careers, the brothers decided to fight in different divisions, in order to avoid fighting against each other.^[4] However, they participated in sparring sessions, performing as they would do against other sparring partners.^[3]

Arroyo represented Puerto Rico in international competition. He won Bronze at flyweight at 2006 Central American and Caribbean Games. In 2007 he participated at the Amateur World Championships and lost in the semifinals to eventual Russian winner Sergey Vodopyanov 9:20, qualifying for the 2008 Olympic Games. After recovering, Arroyo participated in the XXVIII International Golden Belt Tournament organized in Constanta, Romania. Here he defeated local Alex Spatariu in his first fight, who abandoned the fight in the third round. In the semifinals he defeated Mirzhan Rakhimzanov of Kazajistan on points, with scores of 21-16. In the finals he fought against Veira de Jesús of Brazil, defeating him on points (28-16).^[5] As part of their training the boxing team moved to South Korea, in order to assimilate the time changes.^[6] After training and participating in a series of exhibition matches, the team traveled from Korea to Beijing.^[7]

On December 8, 2009, the Arroyo brothers issued a press release through their mother, Milagros Acevedo, informing that they were no longer interested in continuing their amateur careers.^[8] In the letter, they report differences with the criteria used to provide economical support to high-performance athletes, as well as schedule conflicts with their original plans to pursue a professional career after the 2010 Central American and Caribbean Games.^[8] These concerns were restated in a subsequent press conference, where they noted that supporting their respective families was the main reason to pursue a professional career.^[8] On January 12, 2010, PR Best Boxing announced the official signing of both brothers.^[9] Arroyo's debut was scheduled for February 27, 2010, where he competed in the bantamweight division as part of a card titled "Haciendo Historia", where Wilfredo Vázquez, Jr. fought Marvin Sonsona for the super bantamweight world championship. His opponent, Giovanni Rivera, had a previous experience of two professional fights.^[10] The fight began with Rivera moving around the ring, while Arroyo pursued him while engaging on the offensive, eventually scoring a knockdown. After 25 seconds of the second round had passed, he scored a second knockdown, prompting the referee to stop the contest by technical knockout.^[11] In his second fight, Arroyo defeated Steve Cannell by unanimous decision, winning all four rounds.^[12] Next he won a consecutive decision over Jairo Delgado.

In his first six-round fight, Arroyo defeated Jason Rorie by technical knockout. On August 28, 2010, he scored a unanimous decision win over Sigfredo Medina. Arroyo then entered the first knockout streak of his career, which began with a first round victory over Israel Rojas. This run was completed by third and first-round technical knockouts over Eduardo Meléndez and Ivan Moxey. However, Arroyo was forced to rest eight months between these two fights after suffering a chin fracture, making his return in the super flyweight division.^[13][14] He then faced Shawn Nichol in consecutive fights, winning both by unanimous decision in six rounds. On September 27, 2012, Arroyo defeated former world champion José López by technical knockout in four rounds. He repeated this performance against Felipe Rivas, winning the World Boxing Organization's Latino championship. Arroyo returned with a unanimous decision wins over Jairo Hernández in eight rounds. He won the next fight in equal fashion, this time against former contender David Quijano. On June 14, 2014, Arroyo scored an eleventh-round technical knockout over former world champion Hernán Márquez in an International Boxing Federation title eliminator. He gathered knockdowns in the first, fourth, eighth and final rounds.^[15]

On 18 July 2015, Arroyo fought undefeated Arthur Villanueva for the vacant IBF junior bantamweight title. Arroyo started off strong, but after that the fight had a few twists and turns, each fighter having his moments. Near the end of the sixth round, a clash of heads opened a cut above Villanueva's right eye. As the fight went on, Villanueva fought with urgency as he felt the fight might end early due to his severe cut. The fight was stopped in the tenth round because of the cut, and the contest went to the scorecards. Arroyo edged Villanueva, 98-91, 98-91 and 97-92 on the scorecards.^[16][17]

In his first title defence, Arroyo battled Jerwin Ancajas. Ancajas scored a knockdown over Arroyo in the seventh, as he dominated throughout most of the fight en route to a unanimous decision victory. The scorecards were 118-109, 117-110 and 115-112 in favor of the new champion.^[18]

In his next fight, Arroyo fought former world champion Rau'shee Warren. Arroyo boxed well, but Warren was busier and sharper. Warren won on all three judges' scorecards 118-110, 117-111 and 117-111.^[19]

On 16 March 2019, Arroyo battled Luis Nery. Arroyo was dropped by Nery once in the second and third round, and twice in the fourth round. After the end of the fourth round, Arroyo's corner informed the referee to stop the fight.^[20]
