On 9 April 2008, it was announced that Ailyn was chosen as the fourth singer of Sirenia out of over 500 women. "I got selected as Sirenia's new vocalist as an accident," she later told an interviewer. "My sister added them to my Myspace's friends, but we didn't realize that if you wanted to audition for the band you had to send them your demo or add them as friends, so I was shocked when they wrote to me asking to go to Norway and audition for the new vocalist. I went there twice, the first time was a studio audition and the second one with all the band members. I think I was selected because I'm what Morten was looking for the band, and also since the first moment we connected all the members from Sirenia and me."[2]

She was featured on Sirenia's fourth album The 13th Floor, which was released on 23 January 2009.

Sirenia's fifth album The Enigma of Life, was released on 21 January 2011. This made her the only singer who recorded two full-length albums with Sirenia, since Henriette Bordvik only performed vocals on one album, An Elixir for Existence and one EP, Sirenian Shores

In July 2013, Sirenia released their sixth album Perils of the Deep Blue.

On 3 April 2014, the band announced they had returned to Napalm Records with a pending album release for early 2015.[3] The Seventh Life Path, Sirenia's seventh album was released on 8 May 2016.

On 5 July 2016, it was announced via the band's website that Sirenia and Ailyn were amicably separating "for personal reasons", and that the name of the new singer would be announced on 8 September 2016, ahead of the November release of their new album Dim Days of Dolor. The same day, Ailyn stated on her Facebook that she did not make the decision.[4] Her replacement in Sirenia was the French mezzo-soprano singer Emmanuelle Zoldan.[5]

Ailyn recorded four albums in eight years with Sirenia. Until the 2018 release of Arcane Astral Aeons, she was the only Sirenia singer to sing on more than one full Sirenia album. During her stay in Sirenia she also sang some Japanese and Spanish versions of the band's songs, drawing from her previous experiences singing in those languages.

In 2020, Ailyn announced her collaboration with Adrenaline Mob guitarist Mike Orlando in a new project called Her Chariot Awaits.[6] Their self titled debut album was scheduled for release on 10 April 2020, but was delayed due to the COVID-19 Pandemic and released on 22 May 2020.

In 2022, a collaboration with Secret Sphere's guitarist Aldo Lonobile name Lunarian was announced. The debut album entitled Burn The Beauty was released on September 9 that year, with videos for the singles "Dream Catcher" and "Endless Sleep" released.[7][8]

In 2011 she contributed to the Austrian power metal band Serenity's album Death & Legacy, singing the songs "The Chevalier" and "Prayer". She is also featured the video "The Chevalier".

In 2014, she collaborated with several other bands such as the Spanish Metal band Diabulus in Musica, for whom she sang the song "Furia de Libertad" for their album Argia. For the Greek Symphonic Metal band Enemy of Reality, she was featured in the song "Needle Bites" and its music video, from their album Rejected Gods. She performed live with German/Norwegian symphonic metal band Leaves' Eyes at their 10th anniversary show in Wieze, Belgium.

Ailyn Giménez is mentioned in the Dutch metal band The Gentle Storm's album The Diary booklet for useful advice she gave regarding the band's "Shores of India" music video.

In 2015, Ailyn's participation on the new album of the metal opera Melted Space was announced.

In 2017, Ailyn announced her collaboration with Italian metal band Secret Rule: she will be featured on their upcoming album The Key to the World and music video.
