About the role

  • The ideal candidate will be a collaborative team member who contributes to a multidisciplinary engineering group focused on secure, high-performance interoperability for public health and clinical data exchange initiatives.
  • Troubleshoot and resolve interoperability issues, FHIR validation errors, and integration defects.
  • Participate in peer reviews, knowledge-sharing sessions, and team retrospectives to promote continuous improvement.

Responsibilities

  • Collaborate closely with other developers, architects, QA engineers, and DevOps staff to deliver high- quality, maintainable software.
  • Design, develop, and implement HL7 FHIR compliant REST APIs using Java and Spring Boot.
  • Implement and manage FHIR resources, profiles, value sets, and code systems.
  • Build and maintain data transformations between internal data models and FHIR resource structures.
  • Design and implement data transformation pipelines to process diverse data formats-including TSV, XML, JSON, CSV, and HL7 messages-for ingestion, mapping, and exchange.
  • Optimize API performance, scalability, and reliability through code tuning, caching, and asynchronous processing.
  • Maintain clear documentation for APIs, data models, deployment, and versioning.
  • Solid understanding of RESTful API design, JSON, and XML data exchange.
  • Experience building robust data transformation workflows (e.g., parsing, mapping, and serializing TSV, CSV, JSON, XML, NDJSON).
  • Ability to implement schema-driven transformations and validation logic using tools such as JAXB, Jackson, or custom parsers.

Requirements

  • Required Skills & Qualifications Minimum 5 years of professional software development experience.
  • Strong proficiency in Java (Java 11 or higher).
  • Hands-on experience with Spring Boot, Spring MVC, and JPA/Hibernate.

  • Proficiency in relational databases (Oracle, PostgreSQL, or MySQL) and complex SQL queries.
  • Experience with the HAPI FHIR library and associated tools.

Nice to have

  • Bachelor's or Master's degree in Computer Science, Information Systems, or a related field.
  • Certifications in Java, Spring, or FHIR are advantageous.

Benefits

  • Seeking an experienced Java Developer to design, develop, and maintain scalable healthcare data exchange solutions and HL7 FHIR (Fast Healthcare Interoperability Resources) APIs.
  • Develop reusable data parsing, normalization, and validation components to support scalable ETL/ELT workflows in clinical and public health data exchange contexts.
  • Contribute to CI/CD pipelines and DevOps automation for build, test, and deployment processes. (Bonus) Collaborate on frontend development tasks where integration with FHIR APIs or data visualization is needed.
  • Familiarity with HL7 v2.x and other healthcare interoperability standards.
  • Understanding of medical terminologies (e.g., SNOMED CT, LOINC, ICD-10, RxNorm) and their mapping to FHIR value sets.
  • Bonus: Experience with JavaScript and TypeScript for light frontend development or full-stack integration.
  • Bonus: Familiarity with modern frontend frameworks such as React, Angular, or Vue for building healthcare dashboards or API testing interfaces.
