Java Developerย to design
Seeking an experienced Java Developer to design, develop, and maintain scalable healthcare data exchange solutions and HL7 FHIR (Fast Healthcare Interoperability Resources) APIs. 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.
Key Responsibilities
  • Collaborate closely with other developers, architects, QA engineers, and DevOps staff to deliver high-ย  ย quality, maintainable software.
  • Design, develop, and implement HL7 FHIRโ€“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 formatsโ€”including TSV, XML, JSON, CSV, and HL7 messagesโ€”for ingestion, mapping, and exchange.
  • Develop reusable data parsing, normalization, and validation components to support scalable ETL/ELT workflows in clinical and public health data exchange contexts.
  • Optimize API performance, scalability, and reliability through code tuning, caching, and asynchronous processing.
  • Maintain clear documentation for APIs, data models, deployment, and versioning.
  • 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.
  • 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.
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.
  • 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.
  • Practical experience with API security (OAuth2, JWT, HTTPS, authentication/authorization patterns).
  • Proficiency in relational databases (Oracle, PostgreSQL, or MySQL) and complex SQL queries.
  • Experience working in Agile/Scrum environments using JIRA and GitLab or equivalent tools.
  • Proven ability to work collaboratively within a team, mentor peers, and support collective problem-solving.
  • Strong problem-solving skills and ability to debug complex integration issues.
Desired Skills & Experience
  • Direct exposure to HL7 FHIR standards and interoperability frameworks.
  • Experience with the HAPI FHIR library and associated tools.
  • Familiarity with HL7 v2.x and other healthcare interoperability standards.
  • Experience implementing FHIR terminology services and managing value sets/code systems.
  • Understanding of medical terminologies (e.g., SNOMED CT, LOINC, ICD-10, RxNorm) and their mapping to FHIR value sets.
  • Exposure to continuous testing and API monitoring tools.
  • 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.
  • Bonus: Demonstrated ability to collaborate across cross-functional teams including UX, analytics, and operations.
  • Bonus: Experience working with AWS services (e.g., Lambda, API Gateway, S3, RDS) to build cloud-native applications.
  • Bonus: Hands-on experience with Serverless Framework for deploying and managing serverless applications in AWS.
  • Bonus: Understanding of cloud security best practices, IAM policies, and HIPAA-compliant cloud architectures.
Preferred Qualifications
  • Bachelorโ€™s or Masterโ€™s degree in Computer Science, Information Systems, or a related field.
  • Certifications in Java, Spring, or FHIR are advantageous.
  • Contribution to open-source healthcare projects or participation in FHIR Connectathons is a plus.
Work Environment
  • Collaborative, inclusive, and mission-driven environment focused on public health data modernization.
  • Team-based development approach emphasizing shared ownership, peer learning, and open communication.
  • Opportunities for cross-functional collaboration and continuous learning.
