Senior Machine Learning Engineer

About the Company: 

Caire is building a next-generation, virtual-first care platform that puts the patient at the center. This platform will deliver best-in-class integrated shared services and technology to support the launch of multiple new virtual care companies over time. Caire was born out of a novel joint venture between Aegis Ventures, a venture capital studio creating transformative healthcare companies, and Northwell Health, New York’s largest health system. Through this unique arrangement, Caire operates as an independent health tech start up but enjoys the benefits of existing within this larger healthcare ecosystem.


Caire is building the scalable infrastructure which will serve as the backbone for our initial virtual care use cases. Through the creation of a shared operating system across every core function, this infrastructure will minimize time on operations while maximizing time on what really matters – high quality patient care that delivers improved outcomes.


Caire is supported by a multidisciplinary team of clinical advisors, product experts, experienced engineers, and business strategists who are passionate about improving healthcare for all. Come reimagine the future of healthcare with us!
