Staff Platform Engineer

Citizen Health is dedicated to improving care for rare disease patients through an innovative AI platform. They are seeking a Staff Platform Engineer to lead the infrastructure development, ensuring the platform is performant, secure, and compliant with healthcare standards while collaborating with various teams to deliver AI-driven features.

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
