Born in London, England to Irish parents, McNulty moved to New York aged 1 but still calls Dublin his hometown and represented Ireland at both U19 & U20 levels. He represented the New England Free Jacks for their exhibition season in 2019, before being loaned to Rugby United New York (now the Rugby New York Ironworkers) for their inaugural 2019 season. He returned to the Free Jacks for their inaugural season in 2020, a season that was shortened due to COVID-19. McNulty moved across the country to join the LA Giltinis for their inuagural MLR season in 2021, playing a key role in their Championship-winning season. He remained with the Giltinis into the 2022 season but was traded to the Seattle Seawolves part way through in exchange for 2022 Cap Considerations (unknown), and finished the season in the PNW with Seattle on their run to the Championship Final against his former team, Rugby New York. Following the 2022 season, the Seattle Seawolves traded Sean McNulty to the San Diego Legion in exchange for Ben Mitchell, and McNulty remained with the Legion for the 2023 season, again going to the Championship Final but falling 24-25 to the New England Free Jacks. On 21st December 2023, the San Diego Legion traded McNulty to the Miami Sharks in exchange for 2024 Salary Cap Considerations (unknown). McNulty appeared in all 16 Sharks games during their inaugural season, starting 10 times and scoring 2 tries. He set career highs in both metres gained (337m) and tackles completed (122).

As of the conclusion of the 2024 MLR season, McNulty had earned a total of 56 MLR Caps (26 starts) scoring 5 tries. He has featured in the Inaugural Seasons of 4 different MLR Teams: Rugby United New York (2019), the New England Free Jacks (2020), the LA Giltinis (2021), and the Miami Sharks (2024). McNulty appeared in 2 consecutive MLR Championship Finals, the LA Giltinis (2021, won), Seattle Seawolves (2022, lost), and was with the San Diego Legion (lost) for the 2023 Final but did not feature.

Following the 2024 MLR season, McNulty was included in the USA squad for the Pacific Nations Cup, and earned his test debut as Eagle #577 in a win against Canada on August 31st, 2024. On October 23rd, 2024, the Miami Sharks announced the return of Sean McNulty for their 2025 MLR season.
