Hubert was born in Cottonwood, California. He most recently worked as a rear tire changer and a mechanic for Bill Davis Racing's #22 Sprint Cup team, before the team closed down, and also occasionally races road courses for various teams. His hobbies include golf and water skiing.

Hubert made his first Winston Cup race in his first attempt with Jim Wilson's #78 team at Sears Point during the 1997 season. He would bring the #78 Hanes / Diamond Rio Ford home in the 28th position, one lap down. His next start would come in 1998 with the #19 team owned by Kurt Roehrig. He qualified an impressive 10th in his second race at Sears Point, however the #19 Bradford White Ford would finish 41st after a transmission failure 78 laps into the race. His second start during the 1998 season would come at Watkins Glen with Dan Marino and Bill Elliott's #13 team. Hubert drove the #13 FirstPlus Financial Ford to a 36th-place finish. He would return to Roehrig's team in 1999 for three races. His first start would come at Las Vegas where he qualified fourth, finishing in the 28th position. Again, Hubert raced at Sears Point where he would finish in the 33rd position, one lap down. He also attempted the Pepsi 400 at Michigan, however he was unable to qualify. In 2000, he would make one start with Penske Racing and the #12 Mobil 1 Ford. He would finish the Global Crossing @ The Glen in 33rd place after starting 16th. In 2001, Hubert qualified Buckshot Jones' #44 Georgia Pacific Dodge for the Dodge/Save Mart 350. In 2002, he would race the Sirius Satellite Radio at the Glen for Bill Davis Racing. Hubert finished the #23 Hills Brothers Coffee Dodge in the 24th position after starting 40th. He would return to the series in 2004 with Kirk Shelmerdine Racing, driving each of the road courses. At the newly renamed Infineon Raceway (formerly Sears Point Raceway) he would finish 43rd in the #72 Freddie B's Ford after running five laps at too slow of a pace for NASCAR. The Watkins Glen would be much better for Hubert as he would finish in the 29th position just one lap down. He would return to Shelmerdine's team for 2005 and attempt each of the road courses. He would make the race at Infineon, however he finished 43rd after oil pressure problems. Hubert would not make the Sirius at The Glen after qualifying was rained out. Hubert again raced for Shelmerdine in 2006 for the Dodge/Save Mart 350, but was swept up in a crash on the opening lap and once more finished last.
