Our Mission

Healthcare should work for patients, but it doesn’t. In their time of need, they call down outdated insurance directories. Then wait on hold. Then wait weeks for the privilege of a visit. Then wait in a room solely designed for waiting. Then wait for a surprise bill. In any other consumer industry, the companies delivering such a poor customer experience would not survive. But in healthcare, patients lack market power. Which means they are expected to accept the unacceptable.

Zocdoc’s mission is to give power to the patient. To do that, we’ve built the leading healthcare marketplace that makes it easy to find and book in-person or virtual care in all 50 states, across +200 specialties and +12k insurance plans. By giving patients the ability to see and choose, we give them power. In doing so, we can make healthcare work like every other consumer sector, where businesses compete for customers, not the other way around. In time, this will drive quality up and prices down.

We’re 18 years old and the leader in our space, but we are still just getting started. If you like solving important, complex problems alongside deeply thoughtful, driven, and collaborative teammates, read on.

Your Impact on Our Mission

Help shape the future of healthcare communication by building Zocdoc’s AI Phone Assistant Zo, an intelligent voice agent that answers inbound calls for hospitals and doctor’s offices. This is a high-impact, high-growth initiative where you’ll help design, build, and scale AI systems that are redefining how patients and providers connect.

This team builds with emerging tools and approaches, continuously researching, experimenting, and evaluating how AI systems behave in production. Our focus is on designing intelligent flows, orchestration, and decision-making — not just individual model calls.
