Sr. Node Engineer

Ciitizen’s mission is to provide Earth’s 7.3 billion citizens with control of their complete health information and give them the choice of sharing it with whomever they want. Period. With this new ownership, patients can share their health history with caregivers, share for second opinions, and with companies/researchers who may hold the answer to their treatment. 
Current “interoperability” initiatives leave the patient out of the picture and rely on armies of manual labor to extract key health insights from unstructured data—an expensive model that will not scale. And unlike today’s zero-sum “marketplace,” our point of view is that all stakeholders 
share in the value of the data: institutions that participate, app developers through their services, companies that leverage this data for development of potentially life-saving treatments, and patients—who have a strong incentive to share their complete, longitudinal health history with 

 Ciitizen has assembled an all-star team and is backed by strong investment, led by Andreessen Horowitz, Section 32, and Verily Life Sciences.
