JD :

• Design and build backend microservices in Java and Spring Boot, exposing REST APIs (no SOAP).
• Develop healthcare data-exchange functionality supporting HL7-based integrations with pharmacies, referral providers, and external vendors.
• Write efficient SQL against PostgreSQL and SQL Server directly in the data access layer using JDBC (we intentionally avoid ORM frameworks and are moving away from stored procedures).
• Own quality end to end: write unit tests for all code you produce and integration/black-box tests for your APIs, using team frameworks (standardized QTF framework or lightweight HTTP REST client tooling).
• Peer-test teammates changes as part of the JIRA workflow our teams have no dedicated test engineers; developers test each other s code.
• Deploy services through fully templatized pipelines: start from a service template, supply configuration and Helm chart values, and ship to Azure Kubernetes Service (AKS).
• Work in a spec-driven development (SDD) model using AI coding tools primarily Claude Code CLI with reusable skills and specs to generate, extend, and review code.

Required Qualifications

• Strong professional experience with Java, Spring Boot, and REST-based microservice architectures.
• Proficiency writing and tuning SQL (PostgreSQL and/or SQL Server); comfortable working directly with JDBC rather than through an ORM.
• Solid grasp of microservice design principles you should be able to whiteboard and defend a service design in a technical deep-dive interview.
• Hands-on habit of writing unit and integration tests as part of every change (pull requests without unit tests are automatically flagged).
• Experience with AI-assisted, spec-driven development Claude Code preferred; strong Copilot experience is acceptable.
