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.

Requirements

• Has taken FHIR (R4 and/or R5) through a real dev-to-prod journey on a production project
• Has built a custom Implementation Guide or contributed to an existing one — ideally on top of HL7 Europe Base/Core (R5) as the clinical foundation, with awareness of national IG integration
• Has hands-on experience profiling in FHIR Shorthand (FSH) and compiling profiles via SUSHI
• Can translate business/clinical requirements into a FHIR data model
• Has participated in mapping ICHOM terminology to LOINC/SNOMED CT, working alongside a clinician
• Can independently validate FHIR resources against profiles (StructureDefinitions) on a prepared environment
  

Nice to have

• Experience in an EHDS (European Health Data Space) context
• Familiarity with SMART on FHIR at the requirements-specification level (not necessarily implementation)

Benefits

• Remote work: Work remotely from within the EU — due to the sensitive nature of medical data, work outside the EU is not possible for this role.
• 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)
