  • 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.

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