    How do you hire FHIR developers through Agnotic?

    To hire FHIR developers through Agnotic Technologies, you tell us the integration you need and we add engineers who build FHIR R4 APIs, US Core profiles, SMART on FHIR apps and HL7 v2 to FHIR mappings. They join your team or work as a dedicated team, with HIPAA-ready engineering from the first sprint.

    Which engagement model fits your FHIR work?

    The right model depends on who owns the roadmap and how defined the scope is.

    EngagementFits whenWho owns delivery
    Staff augmentationYour team owns the roadmap and needs FHIR depth for an integration or a FHIR server.Your tech lead. Our engineers work in your sprints and your code review.
    Dedicated teamYou want one team to deliver an integration end to end, with QA and a tech lead.Agnotic, with weekly demos to your product owner.
    FHIR projectThe scope is defined: an EHR app, a FHIR API or an HL7 v2 to FHIR migration.Agnotic, against a fixed first release agreed on the scoping call.
    Fractional technical leadYou need FHIR architecture decisions made before you staff the build.You, with a fractional CTO guiding the decisions.
    What They Bring

    Capabilities of Our FHIR Developers

    A FHIR developer turns health data into APIs other systems can trust. These are the skills we check before an engineer joins your project.

    FHIR R4 resources and REST APIs

    They model data as Patient, Encounter, Observation, MedicationRequest and other R4 resources, and build the read, search, create and update interactions, paging and error handling a FHIR server or client needs.

    US Core profiles

    They build and validate resources against the US Core implementation guide, which profiles FHIR for the USCDI data classes used in the United States, and handle must-support elements and missing data correctly.

    SMART on FHIR authorization

    They implement SMART App Launch with OAuth 2.0 and OpenID Connect: EHR and standalone launch, scopes, PKCE and backend services, so apps get only the access they were granted.

    HL7 v2 to FHIR mapping

    They map ADT, ORU and other HL7 v2 messages to FHIR resources in an interface engine or service, keeping identifiers, timestamps and message order intact.

    Terminology

    They bind codes from LOINC, SNOMED CT, RxNorm and ICD-10-CM to the right elements, use value sets, and translate local codes so data lands correctly coded.

    Testing and validation

    They validate resources against profiles, write contract tests for every search the product relies on, and test against vendor sandboxes with synthetic patients only.

    Vetting checklist

    What should a FHIR developer be able to show you?

    Ask for evidence, not a list of acronyms. These are the checks we run before an engineer joins your project.

    1. A FHIR R4 resource model they designed, and why they chose each resource and extension.
    2. The search requests their code relies on, with paging handled and a contract test for each one.
    3. Validation against a US Core profile, including how they treat must-support elements and missing data.
    4. A SMART App Launch flow: the launch context, the scopes requested and how tokens are stored and refreshed.
    5. An HL7 v2 to FHIR mapping that keeps identifiers, timestamps and message order intact.
    6. Code bindings to LOINC, SNOMED CT or RxNorm, and how local codes were translated.
    7. Testing against a vendor sandbox with synthetic patients, never production PHI.
    8. Audit logging that records access to patient data without writing PHI into the logs.

    Engineers join your tools and sprints, follow your access policies and start on the first release.

    Facts and sources

    Which standards do FHIR developers work to?

    Short facts behind the skills we check, each linked to its primary source.

    • HL7 FHIR is a standard published by HL7 International for exchanging health data through RESTful APIs built on defined resources such as Patient, Observation and MedicationRequest.

    • US Core is the HL7 FHIR implementation guide that profiles FHIR resources for the USCDI data classes used in the United States.

    • The SMART App Launch implementation guide uses OAuth 2.0 and OpenID Connect so that apps can launch from an EHR with the user's and patient's context and only the access scopes they were granted.

    • A HIPAA covered entity may share protected health information with a business associate, such as a software vendor, only under a business associate agreement that commits the vendor to safeguard it.
