Senior Data Scientist

HealthTap is hiring a Senior Data Scientist!

Are you excited by an opportunity to leverage huge amounts of data and your skills to solve a fundamental need of all human beings? If so, we have a once in a lifetime opportunity for you to use invaluable health-related data, connect the dots, and help us save lives every day. HealthTap is bringing together the best talent to build a best in class data team in digital health.

Right now, we're looking for a world leading Senior Data Scientist to bring virtual care to billions of people globally safely and securely.  

HealthTap, a World Economic Forum Technology Pioneer, is the world’s first Global Health Practice delivering immediate, world-class healthcare 24/7 from query-to-cure. Through video, voice, and text chat on any mobile device or personal computer, we connect hundreds of millions of people in 174 countries with the most trusted and compassionate health advice from a network of more than 107,000 top doctors.


How does that work?

  • You can search the world's largest library (more than 5.7 billion answers served) of peer-reviewed doctor knowledge for any health topic
  • Or ask help from Dr. A.I, our virtual “physician” who translates your symptoms into personalized, doctor-recommended insights and best course of action—trained by HealthTap’s doctor network
  • And if needed, connect with a doctor for a live virtual consult through voice, video, or text—and get prescriptions, labs tests, and referrals as needed. HealthTap’s proprietary, robust, and secure Health Operating System (HOPES™) and proprietary triaging technology, powered by Artificial Intelligence, enable hospital systems, insurance companies, employers, and governments worldwide to deliver the right care at the right time at the right cost. We generate significant revenue and are funded by some of the world's most reputable investors. Just like the quality of the services we provide, security matters to us most! HealthTap is, therefore, HIPAA-compliant and SOC 2 Type II-certified.

What’s the opportunity?

As a senior member of the data team, you'll have resources, autonomy, and the support of other A-players to drive detection, prevention, and analysis of security threats of the HOPES™ platform and the millions of active patients and doctors on it.


Examples of data projects you could work on:


  • Realize the dreams of Dr A.I., our artificial intelligence powered virtual physician, by enhancing the machine learning model
  • Mine our knowledge base of more than 5.5 billion doctor answers served and improve the lives of millions of people
  • Implement and own deep analysis of very large datasets
  • Real-time trending of health-related issues
