From 1989 to 2000, he worked for the Centers for Disease Control's Epidemic Intelligence Service and the Louisiana Office of Public Health.^[3] During the decade prior to 2009, he was the chair of Tulane's department of community health sciences.^[2] From May 2009 until January 2014, Farley was the commissioner of the New York City Department of Health and Mental Hygiene.^[1] While he held this position, he promoted multiple public health policies in New York City, including banning smoking in the city's parks and beaches, raising the tobacco purchasing age to 21, and oversaw the coordination of the National Salt Reduction Initiative.^[1] He also led the effort to enact the Sugary Drinks Portion Cap Rule.^[4] During part of 2014, he served as the Joan H.

On February 1, 2016, Philadelphia mayor Jim Kenney appointed Farley commissioner of the Philadelphia Department of Health.^[1]

In 2020, as Philadelphia Health Commissioner, Farley approved the city's partnership with the organization Philly Fighting COVID despite the organization's leadership by a 22-year old university student without experience in public health or business management. Farley continued to defend the organization despite warning signs including PFC not granting the city access to data PFC had accumulated; Philly Fighting COVID losing demographic data; and PFC ceasing their testing operations, abandoning community groups who relied on them for free tests.^[7] PFC's CEO Andrei Doroshin would be described by the city as "unprofessional". Philly Fighting COVID was able to test only 20,000 people and vaccinate only 6,800 people.^[8] Farley discontinued the relationship following publication of PFC's change to for profit status.^[8] Calls for disgraced Philly Fighting COVID CEO Doroshin to resign were made by a number of city council members and state senators.^[9]

On May 13, 2021, Mayor Kenney requested Farley's resignation as health commissioner after the public learned that Farley had ordered the destruction in 2017 of the human bodies of victims of the city's 1985 MOVE bombing rather than returning the human remains to the families and without notifying the family of his actions.^[10]
