At the Mark Taper Forum in Los Angeles, he performed in Scenes From an Execution, with Frank Langella. Bernard has made guest appearances on Walker, Texas Ranger, F/X: The Series, Babylon 5, Maloney, and Silk Stalkings and appeared as a regular on the daytime soap opera, The Young and the Restless. He has appeared in the feature films Vegas-City of Dreams, The Killing Jar, and the short film The Colonel's Last Flight.

Throughout all the roles he had, Bernard hadn't reached any major level of success[citation needed] until 2001 when he joined the cast of the FOX Network's television drama 24, where he played Tony Almeida, a government agent for a fictional agency called CTU (Counter Terrorist Unit). Bernard held the role for three seasons until his character, along with several others, was written out at the end of Season 3 (2004). His absence was short-lived, however, as he returned within the first seven hours of the fourth season (2005) credited as "Special Guest Star", and he remained on the show for the rest of the season.

His name returned to be credited on the main cast at fifth season (2006), and it was recently confirmed in a FOX press release that Carlos will return to the show in the season 7 premiere.
