Senior Site Reliability 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 topower 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.

You'll enjoy this role if you are...

• Passionate about observability and believe that teams can't reliably operate what they can't see
• Experienced in integration-rich environments where APIs, third-party dependencies, asynchronous workflows, and distributed services create complex failure modes
• Excited by the challenge of helping a fast-moving engineering organization ship quickly while keeping systems safe, diagnosable, and resilient
• Motivated to turn operational knowledge into reusable platforms, automation, telemetry standards, and paved paths for engineering teams
• Comfortable leading or supporting incident response, communicating clearly under pressure, and using blameless post-mortems to drive meaningful improvements
• Curious about how systems behave in production and willing to investigate across application code, infrastructure, networking, and external dependencies
• Collaborative, pragmatic, and able to build trust with engineers across numerous product development teams
• Autonomous, individually accountable, and always looking for ways to reduce toil and improve the developer and operator experience

Your day to day is...

• Designing, building, and operating observability for distributed services and integrations, including metrics, logs, traces, dashboards, alerts, service-level indicators, and service-level objectives
• Improving end-to-end visibility across critical patient and provider workflows, including identifying gaps in instrumentation and making dependency health and integration failures easier to understand
• Creating reliable, repeatable tooling and infrastructure through infrastructure as code, automation, CI/CD, and self-service patterns
• Partnering with product engineering teams on reliability, scaling, performance, capacity, and failure-mode analysis for services and integrations
• Helping teams establish actionable alerts and operational ownership so that on-call signals are timely, meaningful, and connected to a clear response path
• Participating in the on-call rotation and incident response process, including serving as an incident commander when appropriate and driving follow-up work through completion
• Analyzing and tuning systems, code, cloud resources, and networking for resilience, performance, and efficient operation
• Strengthening deployment and change-management practices so teams can release frequently with appropriate safeguards, rollback paths, and feedback loops
• Contributing to platform standards and reusable patterns for containerized workloads, service communication, secrets, routing, and production readiness

You'll be successful in this role if you have...

• 5+ years of experience supporting consumer-facing web applications, APIs, or distributed production environments in a Site Reliability Engineering, Production Engineering, Platform Engineering, or closely related role
• 2+ years of on-call experience in a 24/7 cloud-based production environment, with a track record of participating in incident response and delivering durable remediation
• Deep experience operating systems with many integrations, services, dependencies, or external APIs, and a practical understanding of how those relationships affect reliability
• Demonstrated experience building or improving observability practices, including metrics, structured logging, distributed tracing, dashboards, alerting, SLIs, SLOs, and error budgets
• 2+ years of experience managing and supporting modern cloud infrastructure, preferably AWS, along with technologies such as Docker, Kubernetes, or similar container platforms
• Proficiency in Python, Go, Ruby, Java, or a comparable language, and the ability to read and troubleshoot application code
• Experience with infrastructure as code and automated delivery practices, such as Terraform, OpenTofu, CloudFormation, GitHub Actions, GitOps, or equivalent tools
• Experience with edge and service networking technologies such as load balancers, reverse proxies, ingress controllers, web application firewalls, routing, rate limiting, or circuit breaking
• A deep understanding of protocols and foundational networking concepts such as TCP/IP, TLS, DNS, and NTP
• Strong written and verbal communication skills, with the ability to explain operational risk, incident findings, and technical tradeoffs to both engineers and partners
• Experience working with sensitive data, privacy or compliance requirements, or regulated production environments is a plus, but not required.

Benefits:

• Flexible work environment based in NYC
• Unlimited Vacation
• 100% paid employee health benefit options (including medical, dental, and vision)
• 401(k) with employer funded match
• Corporate wellness program with Wellhub
• Sabbatical leave (for employees with 5+ years of service)
• Competitive paid parental leave and fertility/family planning reimbursement
• Cell phone reimbursement
• Employee Resource Groups and ZocClubs to promote shared community and belonging
