This paper discusses how occupational closure of the engineering profession in South Africa left Zimbabwean migrant engineers amongst the precariat ranks. It aims to answer the following research question: what is the nature of precariousness experienced by immigrant engineers in South Africa. An exploratory study of the experiences of Zimbabwean engineers is used to test out Standing’s (2011) notion of the precariat as an emerging social class. Semi-structured and group interviews were used as data collection tools. The findings reveal that bureaucratic challenges in obtaining relevant work permits from the Department of Home Affairs, South African universities’ reluctance to acknowledge Zimbabwean qualifications at par with local qualifications as well as a host of insecurities in the workplace left migrant engineers in precariat ranks.
