FHIR SME (HAPI FHIR) - Healthcare Data Modeling (B2B)

About Exerizon At Exerizon, we've redefined the traditional consulting model: we're not just a service provider, but a partner who shares both risk and success with our clients. Why we're looking for you We're building a patient information repository for a large healthcare organization in Poland, using HL7 FHIR (R5) as our data exchange and storage standard, implemented on HAPI FHIR / Smile CDR. Hosting, scaling, and the integration layer (eventing, anti-corruption layer) are handled by our infrastructure team — this role is focused on data modeling, not platform operations. You'll join as a subject matter expert who shapes how clinical data is structured and validated, not just how it's stored.

Impact: A genuine opportunity to shape IT solutions for key market players, without unnecessary corporate bureaucracy. Seniority Culture: Work alongside experts with backgrounds at the world's leading consulting and technology firms. Attractive Compensation: At Exerizon, we value concrete results, so our rates reflect the highest market standard. Private medical insurance (for employees based in Poland)
