Senior Staff Software Engineer - Los Angeles - Circadia Health
Description
About CircadiaHealth
CircadiaHealth 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; predictive analytics & agentic AI workflows that detect 85% of preventable rehospitalizations ~11 days in advance; enterprise integrations that embed insights directly into EHR, care‑coordination, billing, and compliance systems.
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 are headquartered in El Segundo, CA.
$200,000 - $260,000 a year
Why This Role Exists
We are scaling from $100M+ and our back‑end systems must scale faster than revenue. Our predictive models, agentic workflows, device telemetry, and enterprise integrations all depend on resilient infrastructure. As deployments multiply across SNFs nationally, performance, reliability, data integrity, and security become existential.
We need a Senior Staff Engineer who architects and hardens the backbone of Circadia's platform—owning back‑end systems, integration frameworks, and infrastructure reliability at scale. This is not a ticket‑closing role. This is a platform‑defining role.
