Data Annotation, Lead

Prenuvo

4h • $83,000 - $93,000 • Hybrid

About The Position

At Prenuvo, we are on a mission to flip the paradigm from reactive “sick-care” to proactive health care. Our award-winning whole body scan is fast (under 1 hour), safe (MRI has no ionizing radiation), and non-invasive (no contrast). Our unique integrated stack of optimized hardware, software, and increasingly AI, coupled with the patient-centric experience across our domestic and global clinics, have allowed us to lead the change against “we caught it too late again".
We are looking for a Data Annotation Lead to join our dynamic Annotation Team. In this critical role, you will own medical image annotation workflows and quality, ensuring accurate ground truth data to support AI-driven medical imaging research and clinical validation.
This role is preferably based either remotely within the U.S. or in a hybrid capacity in Vancouver to support seamless collaboration with our on-site teams.
