In 2010, Tuli served as Returning Officer for the Chittagong City Corporation election, where she was noted for maintaining control amid political tensions and emphasising adherence to electoral laws.[3] She was reported to be the first female Election Commission official to serve as a returning officer in a city corporation election in Bangladesh and highlighted the importance of transparency and neutrality in the electoral process.[3] In 2014, as returning officer she cancelled the nomination of Sabiha Nahar, Awami League candidate, and Khorshed Ara Haqu, Jatiya Party candidate, due to having outstanding phone bills.[4]
Tuli served as an additional secretary in the Government of Bangladesh.[5] After the fall of the Sheikh Hasina-led Awami League government, she was appointed to the Election Reform Commission.[5]
In November 2024, Tuli was named as an accused in a case filed over alleged attempts to murder during protests associated with the Students' Against Discrimination movement that led to the fall of the Sheikh Hasina-led Awami League government.[5] The case, filed at the Chief Metropolitan Magistrate's Court in Dhaka, included multiple current and former officials and political figures.[5] Legal experts cited in the report questioned the case's basis and described it as potentially harassing.[5]
In January 2026, Tuli stated that many key recommendations of the Electoral Reform Commission had not been implemented and that no major reforms had taken place in Bangladesh's electoral system.[6] She also expressed concerns over continued violations of electoral laws, weak enforcement by authorities, and the lack of an environment in which voters could feel safe during elections.[6]
