We envision a more informed approach to decision-making in drug development, one driven by data and tailored insights into patient selection.

Zephyr is pioneering an innovative AI platform aimed at revolutionizing cancer and cardiometabolic disease treatment paradigms. Through the aggregation of extensive real-world data (RWD) and the application of advanced machine learning techniques, we seek to deepen our understanding of biology, uncovering transformative insights that will reshape the development of new therapies and patient care practices.

For example our oncology models forecast how a patient's tumor will react to specific therapies, even with minimal clinical data and only next-generation sequencing (NGS) information about their tumor. 

ZephyrAI is dedicated to revolutionizing drug development processes, reforming clinical trial methodologies, and making precision medicine accessible to all.



Zephyr AI is seeking a Machine Learning Research Scientist to join our growing multidisciplinary team and lead projects to develop foundation models for Electronic Health Records and implement state-of-the-art representation learning algorithms. You will join a small group of world-class experts to work on state-of-the-art neural networks and push the boundaries of applications of AI to life sciences. Working collaboratively with the research and engineering teams, the ideal candidate will apply their deep technical knowledge in machine learning to design, develop, invent, and implement novel models and analyses to improve patient outcomes and address critical issues in cardiometabolic disease and cancer patient care. This role requires communicating computational results and outcomes to scientists in both quantitative and non-quantitative disciplines and external collaborators. Join us!


We are a team of scientists and engineers dedicated to creating transformative computational tools for healthcare and life sciences and focused on delivering innovative precision medicine solutions to patients with chronic diseases. Our research team builds predictive models to understand cardiometabolic disease and cancer better and to drive product development based on such insights. Our team is flat and self-organizing. We move quickly, but we do good work. We are excited to share our passion for applying innovative AI techniques to save patients' lives with you and for your perspective to help shape our team's goals.
