Senior Full Stack Engineer

Adonis is the leading AI Orchestration platform for healthcare payments, purpose-built for healthcare organizations seeking to transform their revenue operations. Adonis is headquartered in New York City, and raised $31 million in Series B financing in 2024. Our mission is to maximize revenue outcomes that enable healthcare providers to deliver the highest form of clinical care.

Traditional Revenue Cycle Management processes often struggle with inefficiencies, costing providers up to 15% or more of their potential revenue. Adonis addresses these challenges by leveraging advanced automation, data science, and AI to create the infrastructure that RCM teams need to detect vulnerabilities, optimize workflows, and deploy precise solutions that drive reliable and scalable financial outcomes. Whether identifying issues before they escalate, recommending tailored resolutions, or automating the deployment of those resolutions, Adonis creates a seamless, future-proofed approach to RCM.
