After finishing his intensive care training, Van der Voort started working as an intensivist at the Medical Center Leeuwarden in 1998, serving for some years as head of the division. He returned to the OLVG in 2006, working as medical director and educating co-workers and residents. In March 2013, Van der Voort became academic director of the executive master Health Administration at the Utrecht campus of TIAS School for Business and Society, that is affiliated with Tilburg University, next to his job at the OLVG. He also became a professor specialized in health care at Tilburg University in July 2014. He became involved in politics in 2017 when he became a member of the board of D66 in Friesland. As a board member, Van der Voort has served as interim-president of the organization for a few months. He appeared ninth on the D66's party list during the 2019 Dutch Senate election. His party won seven seats, and Van der Voort received two preferential votes out of the 50 votes the party was given – not enough to be elected senator. Van der Voort left the OLVG to start working at the University Medical Center Groningen in October 2019 in the position of intensivist and head of the adult intensive care division. Besides that job, he also became a professor in the field of intensive care at the start of 2020 at the University of Groningen, to which the UMCG is affiliated. He was appointed as a member of the Senate in 2020 to succeed Alexandra van Huffelen because of his position on the party list during the previous election. Van Huffelen had vacated her seat because of her new position as State Secretary for Finance after the resignation of Menno Snel. Van der Voort was sworn in on 4 February. He remained in his other positions, namely as intensivist and professor in Groningen and as professor and academic director in Utrecht. In the Senate, Van der Voort is a member of the Committees for Finances; Education, Culture, and Science; and Public Health, Welfare, and Sport. He held his maiden speech on 16 June.
The COVID-19 pandemic, that reached the Netherlands in February 2020, hit the northern provinces less severe. Because of that, patients from other provinces were brought in to be treated at UMCG's intensive care unit led by Van der Voort. The capacity was raised from about 35 to 112 within a month starting at the end of March. After the pandemic had slowed down, the number of beds was returned to slightly above the initial level in such a way that it can be scaled up again. During two discussions at talk show Jinek, Van der Voort drew attention to the fact that around 90% of COVID-19 patients at the UMCG's intensive care unit were obese. He subsequently co-authored a scientific paper that found that obese COVID-19 patients with respiratory failure had more leptin in their blood compared to an obese control group. Van der Voort hypothesized that this might be a contributing factor to respiratory failure among people with COVID-19 and that the dietary supplement resveratrol might help prevent this.
