Senior QA Engineer

About Circadia Health Circadia Health is a growth-stage healthcare AI company on a mission to prevent avoidable hospitalizations and transform senior-care operations. Our Circadia Intelligence Platform combines: Contactless sensing that monitors respiration and motion with medical-grade accuracy Native predictive models that detect 85% of preventable adverse events several days in advance Enterprise integrations that operationalize predictions directly inside EHR, care-coordination, billing, and compliance workflows Today, our technology touches 40,000+ post-acute patients daily across skilled-nursing, home-health, and home-care networks. We are backed by leading healthcare and AI investors and headquartered in El Segundo, CA. Why this role exists Care teams act on what our platform tells them, which is why we hold our software to a medical-grade quality bar. QA at Circadia is an engineering discipline in its own right: our platform carries 70,000 years of continuous vital signs joined to clinical records from more than 400,000 patients, and verifying it demands the same rigor that built it. You will join our QA team as a senior engineer and help scale that discipline as we grow toward hundreds of thousands of monitored patients — designing test strategy, expanding automation, and producing the verification evidence that supports our regulatory work, so that quality keeps pace with everything we ship.
