National team coach Jill Ellis is stepping down after leading the United States to back-to-back Women’s World Cup titles.

Ellis has been coach of the team since 2014 and has led it to eight overall tournament titles, including victories at the World Cup in 2015 in Canada and earlier this month in France .

“The opportunity to coach this team and work with these amazing women has been the honor of a lifetime,” Ellis said in a statement released by U.S. Soccer today. “I want to thank and praise them for their commitment and passion to not only win championships but also raise the profile of this sport globally while being an inspiration to those who will follow them.”

She will remain with the team for a World Cup victory tour, which kicks off Saturday with a match against Ireland at the Rose Bowl. Following the conclusion of the five-match tour in October, she will serve as a U.S. Soccer ambassador.

Ellis’ contract was set to expire following this year’s World Cup with a mutual option to extend it through the 2020 Tokyo Olympics. U.S. Soccer will begin the search for a new coach after a general manager for the women’s national team is named.

“Jill was always extremely passionate about this team, analytical, tremendously focused and not afraid to make tough decisions while giving her players the freedom to play to their strengths,” U.S. Soccer President Carlos Cordeiro said. “She helped raise the bar for women’s soccer in the USA and the world, and given the history of this program, the level of success she achieved is even more remarkable.”

Over the summer in France, Ellis broke April Heinrich’s U.S. women’s team record for most games coached. Overall, she has led the team in 127 matches, with 102 wins.

Ellis was named head coach after serving as interim coach following the dismissal of Tom Sermanni. Ellis also served as interim coach after Pia Sundhage resigned in 2012.

Ellis was an assistant to both Sundhage and Sermanni. She was on the staff of the gold medal-winning teams at the Beijing and London Olympics. She also served as head coach at UCLA for 12 seasons.

“When I accepted the head coaching position this was the timeframe I envisioned,” Ellis said in the statement. “The timing is right to move on and the program is positioned to remain at the pinnacle of women’s soccer. Change is something I have always embraced in my life and for me and my family this is the right moment.”

The World Cup title in 2015 was the team’s first since winning in 1999. Overall, the team has won soccer’s most prestigious tournament four times.

The United States is set to play Portugal on Aug. 29 in Philadelphia and on Sept. 3 in St. Paul, Minnesota. The final two matches of the victory tour, set for early October, have not yet been announced.
