Former Ireland scrum-half Tom Tierney has been appointed as the head coach of the Ireland women's team.
Tierney takes over from Philip Doyle who stood down after guiding Ireland to fourth spot in this year's World Cup.
The new coach will work under Anthony Eddy, who has been appointed as the IRFU's director of women's rugby.
Eddy, whose previous roles included a spell as head coach of English club Worcester, will also work as the IRFU's director of men's and women's sevens.
Australian Eddy was also previously general manager of rugby sevens at the Australian Rugby Union in addition to serving as an assistant coach at both the ACT Brumbies and Queensland Reds.
In a further appointment, Galway woman Marian Earls has been appointed as the head of strength and conditioning for Ireland's Sevens squads and the women's national team.
Tierney won Ireland caps and has worked with All-Ireland League clubs Garryowen and Cork Constitution.
The former Irish scrum-half coached Ireland's Club International team last year to victories over the English and Scottish counterparts.
Doyle guided Ireland to their first Six Nations Grand Slam in 2013 and his squad shocked defending champions New Zealand at this year's World Cup in August before losing to France in the semi-finals.
Tierney will be in charge of next year's Six Nations campaign in the Spring.
"The establishment of three full-time positions signifies the IRFU's commitment to creating a high performance environment for Irish representative women's rugby," said the IRFU's performance director David Nucifora.
