Following his ordination, he served in various roles throughout the archdiocese, including as a pastor at local churches and as a spiritual director and philosophy director at Mother of Good Counsel Seminary in San Fernando, Pampanga. He was ordained a bishop on his 48th birthday on 27 March 2006, with Cardinal Ricardo Vidal as principal consecrator.

On May 15, 2012, he was named bishop of the Diocese of San Jose Nueva Ecija by Pope Benedict XVI, and was installed on July 10, 2012. He succeeded Mylo Hubert Vergara who was appointed as Bishop of Pasig in 2011.

After the 2017 killing of Fr. Marcelito Paez, Mallari condemned the crime, called for justice and swift investigation. Paez served as a priest in the Diocese of San Jose before retiring. In 2018, Mallari initiated an organic farming training among the farm workers and their families within the Diocese of San Jose's area of jurisdiction. In 2019, he said that child labor is a challenging problem for the Church and the Philippine society and called for cooperation in solving the child labor problem in the country.

From 2015 to 2021, Mallari served as the chairman of the CBCP's Episcopal Commission on Catechesis and Catholic Education (ECCCE). As the chairman of the said commission, he had aired his comments on several issues about the Philippine education system.

In June 2017, he agreed with the proposal of the Philippine Drug Enforcement Agency's to mandatorily test for drugs the teachers and students. Mallari said that the said proposal will prevent the children to be involved with drugs. During the 2017 World Teachers' Day, he expressed support and gratitude towards the teachers and said that their role is important in youth development and reminded them their social responsibility.

He also said his concern about the 2019 closure of 58 Lumad schools in Davao Region by the Philippine government because these schools were allegedly linked to the New People's Army's activity in the area. He said that this was a "failure" of the government to ensure the security of the students and the region's education system.

In October 2019, Mallari rejected the idea that separating girls and boys in schools will lower the teenage pregnancy and HIV infection in the country. This after the National Youth Commission earlier proposed to have separated rooms for boys and girls in schools to curb the said health issues.

During the COVID-19 pandemic in the Philippines, Mallari said in mid-2020 that internet should be maximized for the students' online learning although he agreed that not all students and their families are capable of the said medium. Later that year, he said that education is one of the most "challenged" sectors during the pandemic and said the schools should find ways for alternative learning medium if online learning is not possible.
