# Senior Full Stack Engineer

Ellipsis Health builds AI products that take on healthcare's staffing shortages and administrative burden, pairing conversational AI with our patented voice biomarker technology to help deliver better healthcare for everyone. Our voice agents talk with patients every day: booking and rescheduling appointments, answering billing questions, handling medication refills, and checking in after a hospital visit. This role sits on our provider engineering team, building the platform that connects our agents to the EHRs, scheduling systems, and phone systems inside health systems, provider groups, and FQHCs. You'll work across the provider teams within Ellipsis, partnering with AI engineering, product, deployment, and customer teams to make every new health system go-live faster and more reliable than the last. We're seeking a Senior Full Stack Engineer to build the backbone our AI agents rely on. An agent is only as good as the systems it can act on, and in this role you'll design the APIs, integrations, data model, and durable workflows that connect our agents to EHRs, scheduling systems, and phone systems inside some of the largest health systems in the country.
