Staff Platform Engineer

• We’re hiring a Staff Platform Engineer to build and own the infrastructure that powers Citizen Health — the cloud platform, deployment systems, and reliability practices that let our teams ship AI-driven features safely at speed
• You’ll partner with teams across AI, web, mobile, and data engineering to keep our platform performant, secure, and compliant with healthcare standards (HIPAA, SOC 2, and adjacent frameworks)
• This is a hands-on technical leadership role
• You’ll write code, set the direction for platform engineering, and raise the bar for how the entire org runs in production
• You will likely be the first dedicated infrastructure hire and will build the platform engineering function from the ground up — owning everything from Terraform to on-call until you grow the team
• You’ll report to the Director of Engineering
• Platform & infrastructure strategy — Set the technical direction for our agentic platform. Design architectures that handle long-running AI agent sessions, real-time WhatsApp message delivery, and autonomous tool execution (browser, phone, API calls) — all within HIPAA boundaries. Make the right build-vs-buy calls and keep infrastructure cost-efficient as we scale from hundreds to tens of thousands of active patients
• Reliability & observability — Define SLOs, build the observability stack, drive incident response, and keep uptime boringly high. Make on-call sustainable. When something breaks at 2am, you fix it, write the post-mortem, and spend the next sprint making sure it never happens again — without being asked
• CI/CD & developer experience — Own the deployment pipeline end-to-end. Eliminate friction in the inner and outer loops so teams can ship to production dozens of times a day with confidence. Our AI engineers should be thinking about models and prompts, not fighting deploys
• Inference cost & capacity management — AI inference is our largest variable cost. Partner with AI engineering to optimize model serving, manage GPU and compute capacity, negotiate vendor contracts, and make sure our unit economics work as we scale
• Security & compliance — Partner with security and legal to maintain HIPAA, SOC 2, and related regulatory standards. Implement controls that protect patient data without slowing teams down. Secure the agent tool-use pipeline — when our AI agent opens a browser or makes a phone call on behalf of a patient, the blast radius has to be contained
• Cross-functional partnership — Work closely with Product, AI/ML, Data, and Security to translate platform needs into roadmap. Unblock teams and mentor engineers across the org

Benefits

• Comprehensive health insurance
• Company off-sites
• Work-from-anywhere 30 days of the year
• Unlimited PTO
• Potential for equity
• 12 weeks of paid parental leave

• You’ve been the person who saw a scaling wall six months before it became a crisis, made the case to rearchitect, and then did the work. You’ve led infrastructure through a meaningful inflection — 10x traffic growth, launch into a new channel, migration from monolith to services — and you can talk concretely about what broke, what you learned, and what you’d do differently
• You thrive in early-stage environments where the team is small, the scope is broad, and the best answer hasn’t been written in a runbook yet. You default to data, automate the toil, and document what you learn. You’ve worked at a startup before (ideally sub-50 people) and you liked it
• Experience at an early-stage or high-growth startup where you owned infrastructure broadly, not just a narrow slice
• Demonstrated experience scaling infrastructure through a significant growth inflection (10x users, new product surface, architectural migration) in a production environment
• Excellent written and verbal communication — you’re equally effective in a post-mortem, a roadmap discussion, and a Slack thread
• Proven track record designing for high availability, zero-downtime releases, and graceful degradation in regulated or data-intensive environments
• Strong security fundamentals: IAM, secrets management, network segmentation, vulnerability management, supply-chain security
• Deep expertise running production systems on a major cloud provider (AWS, GCP, or Azure)
• Hands-on with Kubernetes, infrastructure-as-code (Terraform, Pulumi, or similar), and modern CI/CD tooling (GitHub Actions, ArgoCD, Spinnaker, etc.)
• 8+ years of software / infrastructure engineering experience; 4+ years in a senior IC or technical leadership role on a Platform, SRE, or DevOps team
• Strong programming skills in at least one of Go, Python, or TypeScript — you build tooling, not just configure it
• Don’t meet every qualification? We believe that passion, curiosity, and the right mindset matter as much as a checklist of skills. If you’re excited about what we’re building, we encourage you to apply
• Background in healthtech, life sciences, fintech, or other regulated domains (HIPAA, SOC 2, HITRUST, FedRAMP)
• Experience with messaging infrastructure at scale — message queues, webhook reliability, delivery guarantees, rate limiting (WhatsApp, SMS, or similar)
• Experience supporting AI/ML workloads in production — model serving, inference optimization, GPU infrastructure, vector databases, or large-scale data pipelines. This is close to a must-have given our architecture
• Familiarity with FHIR / HL7 or other healthcare data standards
• Experience growing a Platform or SRE function from a small group of generalists into a specialized team
• Familiarity with agentic AI systems, multi-agent orchestration, or long-running autonomous workflows
