On Call Citizen Developer Jobs (NOW HIRING)

Job Summary:
Citizen Health is a company focused on building a personalized AI advocate for rare disease patients. They are seeking a Staff Platform Engineer to own the infrastructure that powers their AI-driven features, ensuring performance, security, and compliance with healthcare standards.
Responsibilities:
• 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.
• 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.
• 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.
• 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.
• 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.
• Work closely with Product, AI/ML, Data, and Security to translate platform needs into roadmap.
• Unblock teams and mentor engineers across the org.
Qualifications:
Required:
• 8+ years of software / infrastructure engineering experience; 4+ years in a senior IC or technical leadership role on a Platform, SRE, or DevOps team.
• 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.).
• Strong programming skills in at least one of Go, Python, or TypeScript — you build tooling, not just configure it.
• Demonstrated experience scaling infrastructure through a significant growth inflection (10x users, new product surface, architectural migration) in a production environment.
• 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.
• Experience at an early-stage or high-growth startup where you owned infrastructure broadly, not just a narrow slice.
• Excellent written and verbal communication — you're equally effective in a post-mortem, a roadmap discussion, and a Slack thread.
Preferred:
• 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 agentic AI systems, multi-agent orchestration, or long-running autonomous workflows.
• Experience with messaging infrastructure at scale — message queues, webhook reliability, delivery guarantees, rate limiting (WhatsApp, SMS, or similar).
• Background in healthtech, life sciences, fintech, or other regulated domains (HIPAA, SOC 2, HITRUST, FedRAMP).
• 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.
