They were first task to manage the national team that will take part at the 2005 Southeast Asian Games. The involvement of Nierras' daughter, Samantha prompted him to take the job as one of the co-manager of the team.

He later became the head coach of the national team. His last stint as head coach was at the 2013 Southeast Asian Games.

Following the Southeast Asian Games campaign, allegations arose that coach Ernie Nierres used stolen credit cards in booking flight tickets of the US-based players, which prompted the concerned players to buy their own tickets due to their tickets being voided for not being authorized. Nierras denied the accusation, insisting that a travel agency was responsible for booking the tickets and not him. In 2014 the national team did not play a competitive match.

In February 2015, it was reported that PFF General Secretary Ed Gastanes said that the women's national team didn't have a head coach. Previously Ernie Nierras was not an A license coach meaning he was not able to continue his coaching stint, leading the team in his last competitive match as coach in 2013. Buda Bautista, appointed in May 2015 succeeded him as head coach.

In July 2018, Nierras temporarily left his club, Stallion Laguna to complete an AFC "A" Coaching Certificate Course.
