Medical Affairs Lead

About Nucs AI

Nucs AI is revolutionizing cancer care through cutting-edge AI and medical imaging technology. Founded in 2024 by a multidisciplinary team of oncologists, AI researchers, and healthcare innovators, we’re tackling one of medicine’s most pressing challenges: the growing demand for accurate, timely cancer diagnostics in the face of rising scan volumes and limited radiologist capacity.

We sit at the intersection of diagnostics and treatment planning—building AI-powered tools at the convergence of medical imaging, radioligand therapy, and artificial intelligence. Starting with prostate cancer and expanding across oncology, we partner with world-leading medical institutions and pharmaceutical companies across the US, Europe, and Australia to bring precision oncology into everyday clinical practice.

Our mission is to enhance diagnostic precision and expand access to expert-level cancer care, improving patient outcomes worldwide. We’re venture-backed, early-stage, and building a team that blends deep clinical expertise with engineering intensity—moving with the rigor the medical field demands and the speed the problem deserves.

The Opportunity

As Nucs AI’s clinical partnerships expand and our products move toward commercial deployment, this role drives the medical affairs engine—scientific communications, KOL engagement, clinical education, and product-market fit from a clinical perspective.

You’ll be the connective tissue between our clinical partners, product team, and the broader medical community. Working alongside the Medical Director and Associate Director of Medical Programs, you’ll translate clinical insights and study results into compelling scientific narratives, educational programs, and market-facing materials that build trust and drive adoption. You’ll also manage the medical annotation team—overseeing the clinicians and specialists who provide the ground-truth labels and expert annotations that underpin our AI models.

If you’re energized by translating clinical science into impact—through publications, presentations, training programs, and physician engagement—this is the role.
