The platform processes healthcare data at national scale, supporting
Patient Access APIs, Bulk FHIR APIs, Provider Directory APIs, SMART on FHIR , and real-time healthcare integration services while maintaining compliance with U.S. healthcare interoperability standards and regulations.
The engineering environment combines
Python, Apache Spark, Kafka, Kubernetes, cloud-native infrastructure, FHIR R4, HL7, REST APIs, OAuth2/OIDC, SMART on FHIR, distributed event-driven architectures, and AI-assisted engineering .
This is an
AI-native engineering environment , where coding agents and reusable AI capabilities are used to accelerate implementation, testing, validation, documentation, and interoperability engineering without compromising correctness, security, or PHI safety.
Requirements:
8+ years of professional experience
in healthcare interoperability, Health IT, backend engineering, or distributed integration platforms.
Proven
Staff-level technical ownership
of complex interoperability platforms and production healthcare integration solutions.
4+ years of hands-on experience implementing FHIR-based solutions , including production FHIR R4 implementations.
Extensive experience integrating multiple
EHR/EMR platforms , including systems such as Epic, Oracle Health (Cerner), Allscripts, athenahealth, eClinicalWorks, Meditech, NextGen, or comparable platforms.
Proven experience implementing
Patient Access APIs, Provider Directory APIs, Bulk FHIR APIs , and other FHIR-based interoperability services.




Production experience integrating with
HIE/HIN ecosystems , including Carequality, CommonWell, eHealth Exchange, TEFCA, or comparable national interoperability frameworks.
Expert knowledge of
FHIR R4 , including resources, profiles, extensions, search parameters, Bundles, validation, and implementation patterns.
Deep understanding of
US Core Implementation Guides, USCDI , and U.S. healthcare interoperability requirements.
Strong knowledge of
SMART on FHIR , OAuth 2.0, OpenID Connect, SMART scopes, backend services, and healthcare authorization models.
Strong understanding of
HL7 v2.x , C-CDA, and healthcare data transformation patterns.
Experience with healthcare terminology standards including
SNOMED CT, LOINC, RxNorm, ICD-10, CPT, and CVX .
Strong hands-on programming skills in
Python , plus experience with at least one additional language such as Java, TypeScript/JavaScript, Go, or C#.
Experience designing and building
RESTful APIs, FHIR APIs, event-driven architectures, and distributed backend services .
Strong knowledge of API security, including
OAuth 2.0, JWT, mTLS, rate limiting, audit logging, and consent management .
Experience with messaging technologies such as
Kafka, RabbitMQ , or comparable event-driven systems.
Experience building distributed systems using
Spark, Kubernetes, Docker , and cloud-native infrastructure.
Strong knowledge of ETL/ELT, CDC, streaming, and asynchronous processing patterns.
Proven experience establishing reusable interoperability frameworks, engineering standards, implementation guides, and technical documentation.
Practical experience using
AI coding agents
such as Claude Code or comparable AI-assisted engineering tools.
Strong engineering judgment regarding deterministic processing versus AI-assisted implementation.
Professional English sufficient for direct collaboration with U.S.-based engineering, product, and clinical stakeholders.
Nice to Have:
Experience with
MPI (Master Patient Index), patient matching, identity resolution , or probabilistic matching algorithms.
Experience with advanced clinical data-quality profiling and anomaly detection.
Experience implementing healthcare consent frameworks such as
FHIR Consent, XACML, DS4P .
Experience with payer interoperability standards including
CARIN Blue Button
and
Da Vinci Implementation Guides
(PDex, CDex, HRex, DTR, PAS).
Experience integrating healthcare wearable ecosystems such as
Apple HealthKit, Google Fit, Fitbit , or comparable platforms.
Experience integrating pharmacy standards such as
NCPDP SCRIPT
and Surescripts.
Experience with laboratory interoperability including
ORU/ORM messaging, LOINC mapping,



DiagnosticReport .
Experience building AI/LLM capabilities for clinical data extraction, terminology normalization, entity resolution, or healthcare interoperability.
Contributions to
HL7/FHIR communities , healthcare interoperability working groups, or open-source healthcare projects.
Hands-on experience with HAPI FHIR, Synthea, or comparable interoperability frameworks.
Responsibilities:
Design, build, and scale
large-scale healthcare interoperability solutions
supporting secure, standards-based health data exchange.
Define technical direction for
FHIR implementation, API architecture, interoperability frameworks, and distributed integration services .
Design and implement
Patient Access APIs, Provider Directory APIs, Bulk FHIR APIs , and related interoperability services.
Build integrations with
EHR/EMR platforms, HIE/HIN networks, healthcare providers, payers, laboratories, pharmacies, wearables, and digital health ecosystems .
Develop robust
FHIR resource mappings, validation rules, transformation pipelines, and interoperability tooling .
Design and implement
HL7 v2.x to FHIR
and
C-CDA to FHIR
transformation engines.
Build automated frameworks for
FHIR conformance testing, interoperability validation, data quality, and integration testing .
Design secure healthcare APIs using SMART on FHIR, OAuth2/OIDC, JWT, mTLS, consent management, and modern API security practices.
Solve complex interoperability issues involving API failures, patient matching, terminology normalization, data mapping conflicts, and compliance requirements.
Define engineering standards, implementation frameworks, and reusable interoperability capabilities adopted across engineering teams.
Make
AI-assisted engineering
a practical part of interoperability development, testing, documentation, mapping, and validation workflows.
Mentor engineers through architecture reviews, technical guidance, pairing, and knowledge sharing.
