Senior Java Developer

About the Role

We are looking for a Senior Java Developer to build and support backend services on a cloud-based data platform. The platform assembles and delivers structured data to internal systems and external partners, and runs in a regulated healthcare environment where accuracy, security, and traceability are as important as delivery speed.

This is a hands-on senior role. You will own work end to end design, implementation, testing, and production support — and be expected to make sound technical decisions with limited supervision.

What You'll Do

  • Design, build, and maintain Java backend services and integrations.
  • Build and harden secure data exchange with external destinations, including credential handling, retry behavior, and delivery confirmation.
  • Work with AWS services in production, including compute, storage, messaging, and secrets management.
  • Write clear SQL and work with relational data models to support new features and troubleshooting.
  • Write unit and integration tests; participate actively in code review.
  • Diagnose production issues using logs and monitoring tools, and drive durable fixes rather than one-off patches.
  • Contribute to technical documentation and runbooks.
  • Participate in Agile ceremonies — grooming, estimation, and sprint planning — and help break larger initiatives into deliverable stories.

Required Qualifications

  • 6+ years of professional software development experience with a strong focus on Java (Java 11 or later).
  • Solid experience with Spring / Spring Boot.
  • Production experience building and operating services on AWS.
  • Strong SQL skills with relational databases (Oracle preferred).
  • Experience with file-based and/or message-driven integrations — batch processing, queues, or event-driven services.
  • Proficiency with Git, CI/CD pipelines, and Maven or Gradle.
  • Demonstrated ability to debug production issues independently.
  • Clear written and verbal communication; comfortable working with non-engineering stakeholders and distributed teams.

Preferred Qualifications

  • Experience in healthcare, diagnostics, or another regulated industry, including handling sensitive data (HIPAA).
  • Familiarity with healthcare data standards (HL7 v2, FHIR).
  • Experience with secure file transfer and external data exchange with enterprise clients.
  • Exposure to Docker and infrastructure-as-code (Terraform or CloudFormation).
  • Experience working under formal change control and documented testing practices.
