At Noah Labs , we are pioneering a new era of digital cardiology . Our flagship technology, Noah Labs Vox , applies advanced machine learning to the human voice to detect early signs of heart failure worsening —earlier than any existing method—transforming how clinicians monitor and manage their patients.

Building on a strong foundation of international clinical trials , we are entering the next chapter: bringing this breakthrough technology to market and expanding the clinical evidence base to establish Vox as the new standard of care .

Together with our deployed remote monitoring platform, Noah Labs Ark —already trusted by more than 200 cardiologists and 1,000+ patients across Europe and the United States—Noah Labs Vox will scale our remote monitoring ecosystem and shape the future of cardiovascular care .

Tasks

1. Core Responsibilities
