Hahn worked in the Missouri Senate Division of Research with roles assistant director and research analyst from 2013 until 2018.

Parson appointed Hahn to the Missouri Public Service Commission on June 1, 2023, [3] and she was named chair on February 6, 2024. [1] In 2023, Hahn worked with her former colleagues in the governor's office to eliminate a proposed rule to report disconnections by ZIP code, a move that had been supported by consumer advocates and commission members for data analysis. Advocates involved in the process said that the governor's involvement in the decision was highly unusual for the commission. The Office of Public Counsel said that any costs associated with collecting zip code data would involve return on investment, including qualification for federal funds to assist customers against shut offs.
