After participating in karting and Skip Barber regional racing, Enerson made his professional debut in the 2012 U.S. F2000 National Championship in National Class. He finished in third place with four class victories. He returned to the series in 2013 driving for ZSports/Team E and finished 9th in the championship with 2 podium finishes at Mid-Ohio Sports Car Course. Enerson switched to his family's own team for the 2014 U.S. F2000 Winterfest and won the championship, capturing two wins and two other podium finishes in the six races. In the 2014 U.S. F2000 National Championship, Enerson finished second in the championship by only 9 points behind champion Florian Latorre. Enerson won five races, the most of any driver that season, including a sweep of both races at Barber Motorsports Park.
Enerson moved two steps up the Mazda Road to Indy in 2015, competing in the Indy Lights series with Schmidt Peterson Motorsports. Enerson took his first Indy Lights victory with Schmidt Peterson Motorsports at Mid-Ohio Sports Car Course after four podiums in the 2015 season.
Enerson started 2016 competing in Indy Lights again, but following the Freedom 100, he dropped out of the series to pursue a seat in the IndyCar Series. This payed off later in the season, when Dale Coyne Racing signed him to drive at Mid-Ohio, then later extended his contract to include Watkins Glen and Sonoma.
