About the role

Responsibilities

  • Lead the architecture and implementation of data integrations with major healthcare payers, including claims feeds, utilization management authorization data, eligibility files, and provider rosters.
  • Build an integration framework that makes onboarding each new payer faster and more reliable over time.
  • Work across healthcare data formats and exchange methods: EDI X12 (837/835/270/271/278), SFTP, flat files, proprietary APIs, and HL7/FHIR.
  • Build monitoring, reconciliation, and data quality systems, including defining requirements, test scenarios, and acceptance criteria for each integration.
  • Build and scale data pipelines for AI/ML systems and analytics dashboards for behavioral and mental health quality and cost.
  • Establish engineering best practices and technical foundations for future team growth.

Requirements

  • 5+ years experience in data engineering, with significant time spent working with healthcare payer data (claims, UM, eligibility).
  • Prior experience leading engineering teams as a tech lead or engineering manager.
  • Hands-on experience integrating with health plan systems and navigating payer data formats including EDI X12, HL7, FHIR, and custom flat files.
  • Strong system design skills with a track record of defining clear requirements, test scenarios, and acceptance criteria for complex data systems.
