Jorgenson grew up in Boise, Idaho, and began racing with BYRDS, the city's youth development squad. He rode for the American junior team Hot Tubes, then spent 2018 with the Continental team Jelly Belly, which released him for half the season to race in Europe with the United States under-23 squad. A place at Chambéry Cyclisme Formation, AG2R La Mondiale's French feeder team, followed, and a single strong summer there was enough for Movistar to sign him for 2020.
He rode the 2022 Tour de France in breakaways, and at the 2023 race he led over most of the Puy de Dôme before being caught inside the last kilometre, taking the combativity award and fourth on the stage, then abandoning days later with crash injuries. His first professional win came that February, on the Jabal Haat summit finish at the Tour of Oman. He was second overall at the Tour de Romandie that spring behind Adam Yates.
He joined Visma for 2024. He started the final day of Paris-Nice 23 seconds behind Brandon McNulty and finished it in the leader's jersey, the first American to win the race since 2006. Dwars door Vlaanderen followed three weeks later, taken alone, 29 seconds ahead of Jonas Abrahamsen. He was second at the Critérium du Dauphiné, eight seconds down on Primož Roglič, and eighth at the Tour de France.
Visma have used him both ways since, as a leader in the week-long spring stage races and as Vingegaard's climbing support in the Grand Tours. He took the 2025 Paris-Nice lead in the stage three team time trial and carried it to Nice, 1:15 clear of Florian Lipowitz.
At the Tour that July he rode through illness in the second week in support of Vingegaard and came home 19th. At the Vuelta he was the last man with Vingegaard in the mountains through the race the Dane won, and took tenth overall himself. He signed an extension with Visma running to 2029.
