(CNN) The city of Ferguson, Missouri, swore in Delrish Moss as its first African-American police chief on Monday.

"Let's go to work," Moss told the crowd at his swearing-in ceremony.

A longtime veteran of the Miami Police Department, Moss was selected from 54 applicants to fill the role. He is expected to help rebuild the Ferguson Police Department after racially charged protests broke out over the 2014 shooting death of African-American teenager Michael Brown by a white police officer.

Moss said Monday the task before the department was to bring "nobility" back to police work.

"If you work hard, if you stay honest and committed, if you maintain respect for the community and do your job well, we will get along just fine," he said, addressing the police officers in attendance.

Moss may be new to the department, but the problems he faces are not. He'll be tasked with healing a fractured community in the spotlight since Brown's shootingof . He'll have to navigate a mostly white police department in charge of a majority black city.

And he'll be expected to reform the department under the wary eye of the U.S. Justice Department.

Moss said he is up to the task. It's a job he's been training for his entire life, starting with his childhood in Miami and throughout his 32 years with the Miami Police Department.

"I think this is a job based on my previous career that I've been training my entire life for," he told CNN's Sara Sidner.

Federal oversight

Moss is replacing Tom Jackson, who resigned last year after a Justice Department report cited racial bias in Ferguson's criminal justice system. The report called for reforms after finding what they called a "pattern and practice" of unconstitutional police conduct in the city.

The federal government sued in February after the Ferguson City Council balked at some terms of a negotiated deal, but the city averted further legal woes in March by unanimously agreeing to accept a Justice Department overhaul of its troubled police force and municipal courts.

In its report last year, the Justice Department highlighted a policing system that uses arrest warrants as generators of income. The report described police practices "shaped by the city's focus on revenue," not public needs.

"This emphasis on revenue has compromised the institutional character of Ferguson," the report said.

African-Americans made up 93% of arrests from 2012 to 2014 but only 67% of the city's population.

The disproportionate number of arrests of minorities was a result of bias, not crime, the report said.

"These violations were not only egregious, they were routine. They were encouraged by the city in the interest of raising revenue," U.S. Attorney Loretta Lynch has said. "They were driven, at least in part, by racial bias and they occurred disproportionately against African-American residents of Ferguson."

Racial distrust

As Ferguson works to recruit more minorities, a big part of the police chief's role will be reaching out to a community scarred by deep racial distrust.

Brown's shooting by white police officer Darren Wilson brought national attention to Ferguson's racial wounds.

But the Justice Department report described a city where officers handcuff minority residents without probable cause, use racial slurs and retaliate against those who question police tactics.

"The residents of Ferguson have suffered the deprivation of their constitutional rights, the rights guaranteed to all Americans, for decades," Lynch said last year. "They should not be forced to wait any longer."

Providing a 'better service'

Moss said he decided to join law enforcement based on two police encounters as a teenager. First, a police officer searched him while he was walking in downtown Miami after dark and called him the N-word. Another time, an officer jumped out of his car and frisked him without notice or warning.

"In both of those experiences nothing was ever done to restore my dignity. I was embarrassed. I was afraid. And I decided then and there that I need to become a police officer. That I needed to provide better service to my community than I was getting," he told CNN.

"If I wanted change in my neighborhood, I had to be apart of it and so I decided to be a police officer, because I couldn't trust my neighborhood, my friends, my family to the police officers that I had met."
