Irazu was an accountant in her region of origin until 2004, but managed her sports career thanks to a high-level athlete job at SNCF where she joined the "World Cup" project group in March 2007, at the Direction de la Communication, since SNCF was a first-rank partner of the 2007 Rugby World Cup.
Irazu is in charge of an initiative to encourage rugby. From 2008 to 2016, she was a member of the steering committee of the French Rugby Federation. In 2017, she was manager of the France Under-20 Women's Team.[2] She was replaced by Hélène Ezanno in 2018.[3]
On December 9, 2017, she was elected to the steering committee of the Ligue Régional Nouvelle-Aquitaine rugby in a list led by Michel Macary and supported by the president of the French rugby federation Bernard Laporte.[4]
