Senior Software Engineer

Our Mission Healthcare should work for patients, but it doesn’t. In their time of need, they call down outdated insurance directories.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 We are looking for a Senior Software Engineer to join the teams that build Zocdoc's provider platform — Provider Infrastructure and Provider Roster Management. These teams create and scale the core systems that: Store and serve provider, location, and roster data as a reliable source of truth. Power onboarding and ongoing management experiences for practices of all sizes, from solo providers to large health systems. Ensure provider changes propagate quickly and safely to downstream systems like Search, Availability, Analytics, and Integrations — so patients always see accurate information. We're building towards a future where Zocdoc can onboard and manage tens of thousands of providers under a single organization in days, not months, with predictable performance and reliability across the stack. Your work will directly improve how quickly providers get live on Zocdoc, how confidently clients manage their rosters, and how reliably downstream experiences behave as we scale. As a Senior Engineer here, you'll balance meaningful individual contribution with mentorship. You'll work across the stack — front to back and everything in between — with an emphasis on robust, observable services and high-scale data flows. You'll take ideas from inception to reality by rapidly iterating, validating with real usage, and hardening systems for long-term scale. You'll Enjoy This Role If You Are… Excited by the challenge of scaling — passionate about building reliable systems with cloud-native infrastructure and event-driven patterns. A product-driven engineer who enjoys partnering closely with PM, design, Ops, and analytics to solve real customer problems. Motivated by building products that make healthcare easier for providers, operations teams, and patients. Excited to use technology to simplify complex workflows — turning messy, high-volume data into clear, predictable experiences. Passionate about building diverse and inclusive teams and culture. Curious about how AI and GenAI can responsibly improve developer productivity and provider experiences (e.g., smarter prefill, better insights), while staying grounded in real value. Your Day to Day Is… Building and evolving services and tools that power our scaling initiatives across Provider Infrastructure and Roster Management. Writing clean, well-tested code across C#, React, and AWS-based services. Collaborating closely with engineers, PMs, designers, and Ops to shape solutions from idea to launch. Contributing to service migrations away from legacy systems toward modern, event-driven architectures. Using metrics, dashboards, and load tests to keep services healthy and observable as usage grows. Sharing knowledge and feedback to help
