Senior Site Reliability Engineer, Citizen Health

• If you're passionate about building systems that stay up, scale well, and recover fast—and you thrive on solving reliability challenges in modern cloud-native environments—we’d love to talk to you
• You are a hands-on Senior Site Reliability Engineer who thrives in fast-paced, high-stakes environments where reliability is mission-critical. You bring deep experience operating distributed systems at scale, with a strong foundation in cloud-native infrastructure, Kubernetes, and observability
• You think like a software engineer but focus like an operator—using code to solve operational challenges. You’re driven by making systems more resilient, reducing downtime, and building fault-tolerant architectures that scale with user demand
• You value data-driven decision making, and see SLIs/SLOs, incident postmortems, and continuous improvement as essential tools—not checkboxes
• You have a strong sense of ownership, thrive under pressure, and believe the best systems are the ones that heal themselves. You collaborate closely across teams, care deeply about the end-user experience, and are always looking for better ways to keep complex systems running smoothly
• 5+ years in Site Reliability, DevOps, or Infrastructure Engineering roles
• Strong software engineering skills in languages such as Python, Go, or Bash
• Deep expertise operating production systems in AWS, with additional experience in GCP or Azure
• Proven experience operating and scaling Kubernetes (EKS) in production
• Experience implementing GitOps with FluxCD (or similar)
• Hands-on experience implementing observability, auto-scaling, and self-healing systems
• Strong foundation in networking, load balancing, CDN, and container orchestration
• Solid knowledge of performance optimization techniques (e.g. profiling, caching, tuning)
• Strong incident response background, including postmortems and SLO/SLI development, driving improvements through data and analysis
• Passion for reliability, automation, operational excellence, and building systems patients and clinicians can trust
• Excellent communication and collaboration skills
• A methodical approach to problem-solving and system design

Desirable

• Citizen Health is seeking a Senior Site Reliability Engineer (SRE) to ensure the resilience, performance, and availability of our AI-powered, patient-centric healthcare platform
• In this hands-on, high-impact role, you will apply software engineering principles to operational challenges—designing and maintaining reliable systems that scale, fail gracefully, and recover quickly. You'll work cross-functionally to establish SLOs/SLIs, implement robust observability, establish a metrics-driven approach to service performance, and drive improvements in incident response, fault tolerance, and service reliability
• Define and measure service reliability through SLIs, SLOs, and error budgets
• Implement and operate observability tooling (e.g., NewRelic, Prometheus …) across cloud and Kubernetes environments
• Analyze logs, traces, and metrics to surface actionable insights and improve system health
• Perform capacity planning, load testing, and performance profiling and tuning to support scale and reliability, and to optimize system performance
• Design and maintain resilient, self-healing infrastructure in AWS and Kubernetes (EKS)
• Conduct chaos engineering experiments, failure mode analysis, and disaster recovery drills to proactively identify and fix weaknesses
• Build automation to reduce toil, improve reliability metrics (latency, uptime, error rates, MTTD, and MTTR), and prevent recurrence of incidents
• Engineer infrastructure for fault tolerance, auto-scaling, and graceful degradation
• Drive incident response efforts, manage on-call rotations, and coordinate resolution of production outages
• Conduct root cause analyses and blameless postmortems to drive learning and resilience
• Continuously improve key reliability metrics such as latency, uptime, error rates, and availability
• Collaborate with security, platform, and DevOps teams to ensure high-availability and production-readiness of services
• Collaborate with engineering teams during design and architecture phases to assess and mitigate reliability risks
• Support progressive delivery strategies including feature flags and canary deployments
• Champion SRE principles and practices, helping build a culture of resilience and shared ownership
• Stay current with emerging practices in cloud reliability, observability, and SRE tooling
