Software Development Louisville, Kentucky 1,001–5,000 employees Public Company

Waystar operates a mission-critical healthcare payments platform spanning 60% of U.S. patients and processing over $2.4 trillion in annual claims volume across 30,000 provider clients. The tech stack—anchored in Epic/Cerner integrations (HL7, FHIR, ANSI X12), Snowflake data warehousing, and polyglot backend (Python, Java, .NET, Go)—reflects a systems integrator's complexity: managing clinical data translation at scale while building AI features atop legacy healthcare standards. Hiring is accelerating with engineering-heavy emphasis (25 roles), suggesting active work on ML platform development and data engineering for model training to address the core pain point: extracting signal from unstructured clinical documentation in revenue-cycle workflows.
