Results: We analyzed the data from 1007 global health job vacancies from 127 employers. Among private and non-profit sector vacancies, 40% (n= 354) were for technical or subject matter experts, 20% (n= 177) for program directors, and 16% (n= 139) for managers, compared to 9.8% (n= 87) for entry-level and 13.6% (n= 120) for mid-level positions. The most common technical focus area was program or project management, followed by HIV/aids and quantitative analysis. The thematic analysis demonstrated a common emphasis on program operations, relations, design and planning, communication, and management.
Conclusions: Our analysis shows a demand for candidates with several years of experience with global health programs, particularly program managers/directors and technical experts, with very few entry-level positions accessible to recent graduates of global health training programs. It is unlikely that global health training programs equip graduates to be competitive for the majority of positions that are currently available in this field.
