Key Responsibilities

  • Design, develop, and maintain system integrations across BPaaS platforms (claims, billing, clinical, member/provider, etc.).
  • Develop robust, reusable applications to support data transformation, workflow automation, and integration pipelines.
  • Configure and manage integrations leveraging OnBase middleware (or comparable tools such as MuleSoft, Boomi, Informatica, Talend, SnapLogic).
  • Collaborate with business analysts, architects, and QA to deliver high-quality, scalable solutions that meet business and compliance requirements.
  • Support ETL processes, ensuring accurate data extraction, transformation, and load into target systems.
  • Participate in solution design sessions, code reviews, and technical documentation.
  • Troubleshoot, optimize, and enhance existing integrations to improve performance, resilience, and maintainability.
  • Ensure all integrations comply with security standards, HIPAA/SOC2 requirements, and corporate governance policies.
  • Mentor junior developers and contribute to best practices for coding, version control, and integration management.

  • 7+ years of experience in software development and system integration.
  • Strong expertise in Python (automation, APIs, data transformation, scripting, packages).
  • Hands-on experience with Edifecs middleware or equivalent ETL/integration tools.
  • Proficiency in designing and consuming REST/SOAP APIs, message queues (Kafka, RabbitMQ), and file-based integrations (SFTP, flat files, JSON, XML).
  • Solid understanding of databases (SQL Server, Oracle, PostgreSQL, or similar).
  • Experience in cloud platforms (Azure, AWS, GCP) and hybrid integration patterns.
  • Strong debugging, problem-solving, and performance optimization skills.

Preferred:

  • Experience in healthcare payer systems (claims, enrollment, clinical, billing, provider/member).
  • Familiarity with HealthEdge HRP, GuidingCare, Edifecs, or similar platforms.
  • Knowledge of DevOps pipelines (CI/CD, Git, Jenkins, Azure DevOps).
  • Prior work in a BPaaS or SaaS multi-tenant architecture environment.
  • Experience mentoring or leading small technical teams.

Soft Skills

  • Strong collaboration skills with cross-functional teams (business, QA, operations).
