Senior Software Engineer

Our Mission You call. You wait. You call again. In every other part of your life, you book in seconds. In healthcare, you’re blocked. We’re here to give power to the patient. For nearly 20 years, we’ve built the leading healthcare marketplace - helping tens of millions of people find and book the care they need. Now, we’re going further: building our infrastructure beyond Zocdoc’s marketplace to power access to care wherever patients search, from provider websites and insurance directories to search engines, AI platforms, and more. Healthcare still lacks something every other major consumer industry takes for granted: a seamless way to go from seeking to getting . We don’t want to own the front door to care; there isn't one. We want to make sure all of those doors open when patients are knocking. Fixing healthcare starts with fixing access to it. And we're still just getting started. 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 toward a future where Zocdoc can onboard and manage tens of thousands of providers under a single organisation 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 the team move faster and make better technical decisions.
