As a founding engineer, you’ll own the systems that make Backbone work: chart ingestion, document processing, claims workflows, browser and computer-use automation, payer portal navigation, orchestration, queues, reliability, auditability, and the infrastructure needed to scale from thousands of charts and claims to hundreds of thousands. Today, U.S. healthcare wastes more than $350B yearly on administrative work that has nothing to do with patient care: prior authorizations, denials, appeals, and the staff hired on both sides of the aisle to adjudicate and determine payment for services rendered.
