Senior Interoperability Engineer

We are looking for a Senior Interoperability Engineer to build and scale healthcare integrations for a Digital Health platform connecting providers, payers, clinical systems, and external healthcare networks. This is a hands-on engineering role focused on Python, Kafka, high-scale APIs, healthcare interoperability, and secure data exchange. The platform connects healthcare data from multiple clinical and administrative systems and makes it available through secure, standards-based APIs. The Interoperability domain is responsible for building and operating integrations with external healthcare systems, processing high-volume data exchange, and providing reliable APIs consumed by internal products and partners. The engineering environment is based on Python, event-driven architecture, Kafka, REST/FHIR APIs, OAuth-based security, and cloud-native services. Requirements: * 5+ years of professional backend or integration engineering experience. * Strong hands-on experience with Python in production environments. * Experience designing and operating high-scale REST APIs and backend services . * Strong experience with Kafka or comparable event-streaming technologies. * Solid understanding of distributed and event-driven architectures . * Strong experience with API authentication and authorization, including OAuth 2.0, OIDC, and JWT . * Experience integrating external systems and APIs in complex enterprise environments. * Hands-on experience with FHIR or healthcare interoperability APIs . * Strong understanding of API reliability, error handling, retries, idempotency, and observability. * Experience with SQL and/or NoSQL databases. * Experience with Docker, cloud-native environments, and CI/CD. * Strong troubleshooting and production problem-solving skills. Nice to Have: * Experience with FHIR R4, SMART on FHIR, US Core, or USCDI . * Knowledge of HL7 v2 or CDA/C-CDA . * Experience integrating EHR/EMR, payer, HIE/HIN, pharmacy, or laboratory systems. * Experience with Patient Access APIs, Bulk FHIR, or CMS interoperability requirements. * Experience with Kubernetes and AWS. * Healthcare or Digital Health domain experience. * Experience using AI-assisted engineering tools in day-to-day software development. Responsibilities: * Design and develop scalable healthcare interoperability services and APIs . * Build event-driven integrations using Python and Kafka . * Implement and support FHIR-based healthcare data exchange. * Develop secure APIs using OAuth 2.0/OIDC and JWT . * Integrate external healthcare systems, data providers, and partner APIs. * Implement data validation, transformation, mapping, and error-handling logic required for interoperability workflows. * Troubleshoot complex integration, authentication, and distributed-system issues. * Improve API performance, scalability, reliability, and observability. * Build automated tests covering API behavior and integration scenarios. * Participate in architecture discussions, code reviews, and engineering standards. Build core interoperability capabilities for a large-scale Digital Health platform. You’ll work on high-volume healthcare integrations, secure APIs, Kafka-based event processing, and FHIR interoperability rather than traditional ETL or analytics pipelines.
