The 47-year-old becomes the eighth coach in program history, having served on an interim basis after Tom Sermanni was fired last month.
U.S. Soccer on Friday announced Ellis as the eighth head coach in women's national team history, handing the permanent job to the 47-year-old. Ellis has compiled a 6-0-3 record while twice holding the position on an interim basis, including matches against China and Canada following Tom Sermanni's firing last month.
"Jill has been on the bench for more senior and youth women's national team matches than perhaps any coach in United States history," U.S. Soccer president Sunil Gulati said in a news release. "She has worked at this for many years and has tremendous knowledge of our player pool and the qualities of multiple generations of players.
"We are confident she is the best person to find the right combinations on the field to make us successful in World Cup qualifying and beyond. She has experienced firsthand the growth of women's soccer worldwide and is uniquely positioned to lead our team to an even higher level."
Ellis served as an assistant on the U.S. squads that claimed the Olympic gold medal in 2008 and 2012, and has previously served as coach of the U.S. Under-20 women's national team. She will step back from her post as U.S. Soccer's women development director after taking over that role in 2011.
"It's a huge honor," Ellis said. "I'm humbled and proud to lead the current generation of players toward the ultimate goal, a FIFA World Cup championship."
