Artificial Intelligence
Arbital Health is a rapidly growing healthcare technology and actuarial leader that centralizes, measures, and adjudicates value-based care contracts at scale. We enable payers and providers to design, measure, and execute value-based agreements with greater transparency, efficiency, and financial predictability.
We invest in hiring high potential and humble individuals who thrive in fast-paced environments and can rapidly grow their responsibilities as we continue to accelerate our growth.
We were co-founded by Brian Overstreet and Travis May (founder & former CEO of LiveRamp and Datavant, the two biggest data companies of the last 20 years), and are backed by Transformation Capital, Valtruis and other leading investors. In our first 2 years, Arbital Health has established itself as a trusted partner for over 40 payers, providers, and other stakeholders looking to navigate the complexities of risk-based contracting.
At Arbital Health, we aim to transform the US healthcare system by accelerating the shift to value-based care (VBC) contracts by building the first AI-powered platform that enables our customers to construct, measure, and adjudicate VBC agreements. We recently launched Merlin AI, the first VBC AI assistant which makes complex contract performance data conversational, transparent, and instantly actionable.
We are looking for a visionary, hands-on Senior AI Engineer to drive product innovation by architecting, building, and scaling Merlin's next-generation conversational AI experiences. This role requires a technologist who excels at the intersection of advanced AI models, large-scale systems, and a customer-focused approach.
Is this role right for you?
