This study reconstructs a typology of coordination modes in the university third space, drawing on externally funded HE development projects at German universities. It asks how project coordinators enact steering and which ideal-typical coordination modes can be identified. Previous research on third-space roles and projectification describes the growing relevance of hybrid management positions in HEIs yet lacks an empirically grounded typology specifying steering orientations and forms of embeddedness. Conceptualising project coordination as a governance resource, the study proposes two analytical dimensions structuring a four-mode typology. Drawing on 20 qualitative guideline interviews and reconstructive ideal-type comparison, it derives four modes with distinct role self-understandings, instrument repertoires and decision pathways. The typology refines understanding of managerial roles in the third space and offers guidance for integrating such positions into HE governance, with implications for systems where projectification is salient.
