The United States women's national team will have a full-time head coach for the first time after Rob Cain accepted an offer to join the Eagles.
Cain will arrive at the Olympic Training Site in California, pending visa approval, this summer following four seasons as head coach and director of rugby at Saracens Women.
His time with the English club has been highly successful and was rounded off last month as he led Saracens to victory in the inaugural Tyrrells Premier 15s final.
"I am both humbled and excited for such an incredible opportunity to join the USA Rugby family and become the first full-time women's national team head coach," Cain said.
"I want to thank both Saracens and USA Rugby for their patience throughout this extensive process, I am looking forward to our journey to the 2021 World Cup."
