You will own the customer relationship end-to-end, partnering closely with both senior client stakeholders and users to drive adoption, value realization, retention, and growth across either H1’s Clinical or Medical & Commercial product lines. This role is designed for a highly autonomous, principal-level Customer Success leader who thrives in ambiguity, independently owns complex customer programs, strong personal accountability, and influences outcomes across customers, partners, and internal teams.
