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: Zocdoc is looking for a Senior Site Reliability Engineer to make our distributed production systems more observable, reliable, and safe to change. Our platform connects patients, providers, and many interconnected services and integrations, so reliability depends on understanding the full path of a request—not just whether an individual service is running. You’ll help build the observability foundations, automation, and engineering practices that allow Zocdoc to move quickly without sacrificing safety. You’ll work across cloud infrastructure, microservices, APIs, and integration points in AWS, partnering closely with product engineering teams to identify risks, improve operational visibility, and make the right behavior easier to build and operate.
