Mid-Level Full Stack Developer | Defense Health Agency (DHA)

Stratitia is seeking a Mid-Level Full Stack Developer to serve as a core member of an Agile team supporting the Defense Health Agency’s operational medicine and blood-management software portfolio. You will translate operational needs into secure, tested software spanning user interfaces, services, data stores, and external interfaces. Why This Role Matters: The software supports time-sensitive donor, inventory, distribution, and transfusion workflows. Success requires more than feature delivery: the right candidate will protect traceability, transactional accuracy, system interoperability, and dependable operation when connectivity is disrupted or limited. What You Will Do:

• Design and implement front-end and back-end components for prioritized features, enhancements, and defect corrections.
• Translate user stories, functional rules, interface specifications, and acceptance criteria into production-quality software.
• Develop and support APIs, services, data-access components, and adapters used to exchange information with external systems.
• Implement validation, auditability, error handling, and transactional controls appropriate for regulated healthcare and logistics workflows.
• Diagnose complex defects across application, database, interface, and deployment layers; provide clear root-cause analysis.
• Contribute to offline-first or limited-connectivity capabilities, including synchronization, retry, idempotency, and conflict handling.
• Create unit and integration tests, participate in peer reviews, and improve automated regression coverage.
• Estimate work, identify dependencies and technical risks, and communicate progress within Agile planning and delivery ceremonies.
• Partner with architecture, test, data, DevSecOps, cybersecurity, and functional teams to move changes through release readiness.
• Maintain technical documentation, interface details, configuration records, and evidence supporting secure Government delivery.

• Bachelor’s degree in Computer Science, Software Engineering, Information Systems, Information Technology, or a related technical discipline.
• Three to seven years of relevant software-development experience delivering full-stack applications.
• Demonstrated proficiency in an object-oriented back-end language or runtime and a modern web user-interface framework.
• Hands-on experience with RESTful APIs or other application interfaces, relational databases, SQL, source control, and automated testing.
• Experience implementing business rules, data validation, exception handling, and defect corrections from documented requirements.
• Working knowledge of secure coding, dependency management, logging, configuration management, and code-review practices.
• Ability to troubleshoot across application layers and collaborate effectively with distributed, cross-functional teams.

• Strong written communication skills for design notes, test evidence, operational impacts, and technical decisions. Preferred Qualifications:

• Experience with C#/.NET or Java; JavaScript or TypeScript; and React, Angular, Vue, or a comparable user-interface framework.
• Experience with SQL Server, PostgreSQL, Oracle, or another enterprise relational database, including schema changes and performance tuning.
• Experience designing synchronization, reconciliation, or resilient data-exchange workflows for disconnected or degraded networks.
• Familiarity with healthcare interoperability or enterprise interfaces, including REST, SOAP, messaging, file exchange, HL7 v2, or FHIR.
• Experience with containers, CI/CD pipelines, infrastructure automation, code-quality gates, or cloud-hosted platforms.
• Knowledge of Section 508 accessibility, OWASP guidance, DoD DevSecOps, RMF/ATO, STIGs, or Government vulnerability-management processes.
• Experience with military health, blood operations, medical logistics, regulated inventory, barcode-enabled workflows, or chain-of-custody systems.
