Upon her return to Bulgaria, she taught history, geography, Bulgarian and Russian in Shumen 1905–07 and then at her old school in Sofia from 1908 to 1918. After the war, Zlatoustova became one of the few women to work for the government, initially in the Ministry of Education and Science and then as the head of department for cultural institutions and funds from 1918 to 1931.
